SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 13 Installing the RF-MANAGER 3.3 Installation Service Pack 14 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4 The following will familiarize you with the sample project. As well as a description of the project, this also includes a run down of the possible uses. You can try out the individual components of the project in Runtime using the simulator included in the scope of supply. The simulator is used to simulate operation of the readers configured in the Runtime system as well as pre-defined tag events. 4.1 Description of the project The sample project represents a simplified RFID scenario. This scenario consists of an RFMANAGER Workstation to which three readers and a PLC are connected. In addition, there is an ALE connection between the RF-MANAGER Workstation and a higher-level enterprise system. The readers and the functionalities connected with them are the central elements of the scenario. Labelling The reader "Reader_Labeling" is controlled via a light barrier and uses two antennas to monitor a conveyor belt via which goods are transported in crates. These goods are destined for different recipients. Each crate is equipped with a tag. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 15 Using the sample project 4.2 Starting the project with the simulator When a crate breaks through the light barrier, the conveyor belt stops automatically and the reader reads the current tag. The current values are displayed in an appropriate screen. It is now possible to edit the values and write the changed values to the tag. A distinction is made between two types of crates here: After the write, the conveyor runs again. Sorting The goods must be sorted in a second step. There is a separating filter for this purpose downstream of the conveyor that determines the pallet to which the goods should be directed. When the light barrier is broken, the reader "Reader_Sorting" reads the tag with its two antennas. The values are supplied to a PLC. The separating filter is set by the PLC according to the read results. Downstream of the separating filter, the crates are loaded onto pallets. Each crate is equipped with a tag. An additional tag is also applied to each pallet. The additional tags too receive tag data specific to the goods recipient. Outgoing goods The reader "Reader_Gates" uses two antennas to monitor each outgoing goods gate. At each outgoing gate, the tags of the pallet and the crates that are located on it are read. The values are evaluated in a script. This allows you to check whether the correct pallets complete with the correct goods are ready at the recipient-specific outgoing goods gate. Incorrect pallets are stopped and must be acknowledged. Permitted pallets are loaded immediately. The read results of the reader are forwarded by the Runtime software to the higher-level enterprise system via the ALE interface. 4.2 Starting the project with the simulator The RF-MANAGER is supplied with simulator software which you can use to test the components of the sample project. The simulator is a separate application. You can use the simulator to simulate operation of the readers configured in the Runtime system as well as pre-defined tag events and reader inputs. 16 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.2 Starting the project with the simulator Simulation of readers and tags The simulator works with pre-defined and modifiable simulation tables "Getting_Started_2008.Device_1.rfidsim". These are opened automatically. RFID jobs with tag events have already been created in the simulation tables for each of the three readers. These jobs are mutually independent and can execute once only or in cycles. Each job is assigned a tag ID for the simulation. The parameters "OnTime" / "OffTime" define how long the tag of the corresponding job is within the measuring range of the reader antenna (visibility). If the job is cyclical, the ratio of visible/invisible is set using the two parameters. When an input is configured for the trigger condition, the job is triggered in accordance with the parameters set. Special characters (wildcards) can be used in the tag ID to generate random tag IDs (see the online help of the simulator). Similarly one job can be used to generate several tags when the number is greater than 1 and the random pattern is set appropriately. The created jobs can be set to active or inactive. If you want to modify the simulation table, you can also reproduce the jobs, for example, and then delete individual jobs. Note Changes to existing tag jobs If you change the type (leading characters), length of the tag or the trigger conditions, the functionality in the project may no longer be assured. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 17 Using the sample project 4.2 Starting the project with the simulator Starting the project with the simulator Note Engineering System and Runtime System on the same PC The sequence of actions described below refers to the scenario in which the Engineering System and Runtime are installed on the same PC. If you operate the Engineering System and Runtime on different PCs, you will find the information on transferring and starting projects in the SIMATIC RF-MANAGER Configuration and Operating Manual. 1. Unzip the file "Getting_Started.exe" from the CD in the path: Documents\English\GettingStarted into a directory of your choice. 2. Start the RF-MANAGER Engineering System, either by clicking the desktop icon on the programming device or by selecting it from the Windows Start menu. 3. In the Engineering System, select the option "Open existing project". 4. Navigate in the path used above to the project file Getting_Started_2008.rfid". 5. Click "Open". The project opens. 6. If you are asked if the project has been created with an older RF-MANAGER version and if you would like to convert, confirm this message with "Yes". Usually this query is only displayed if there is an installed ServicePack. 7. Click on "Project / Generator / Start Runtime with simulator". The already created simulation table for the sample project is opened by the simulator automatically. All the settings made for simulation of the project are stored in the simulation table "Getting_Started_2008.Device_1.rfidsim". The simulator then starts the Runtime software and starts to simulate the values. 18 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.3 Using the project 4.3 Using the project The Start screen appears after starting the project in Runtime. The sample scenario is visualized on this screen. You can reach other screens using the buttons of the start screen. These can be grouped as follows: Scenario screens: Labelling Sorting Outgoing goods System displays: Configuration Alarms In addition, language switching can take place in the start screen and Runtime can be terminated. You can jump back to the start screen from any other screen. If alarm events occur during operation of the sample project, these are automatically visualized via the alarm window. The alarm window cannot be selected via a button, but appears automatically at each alarm event. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 19 Using the sample project 4.3 Using the project Labelling The "Labeling" button takes you to a screen that shows the functionality of labeling: 1. Select the "Start conveyor" button. When a crate breaks the light barrier, the conveyor belt is stopped and the tag is read. The read data is supplied in the form of variables over an RFID data link and displayed under "Current tag ID". The tag ID is presented in raw hexadecimal format and after conversion in tag format. The serial number is then extracted from the tag format. You can now check the serial number and change it if necessary. 2. This is done by editing the "Serial number" input field and confirming it with the <Return> key. The changed tag ID overwrites the current values in the display fields under "New tag ID". 3. Select the button "Write tag ID" to write the changed serial number to the tag. After the ID has been written again, the conveyor will run. The crate will be displayed in different colors in accordance with the assigned serial number: - Odd serial number: Red crate - Even serial number: Green crate 4. Select the "Stop conveyor" button to stop the scenario. Click the "Back" button to display the start screen again: 20 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.3 Using the project Sorting The "Sorting" button takes you to a screen that shows the functionality of sorting: 1. Select the "Start conveyor" button. When a crate breaks the light barrier, the tag ID is read. The read data is supplied to the PLC in the form of variables over an RFID data link. The PLC is switched offline for the simulation. The control program evaluates the tag IDs and decides on the basis of the serial number (even or odd) how the separating filter of the conveyor should be set: - Red crates (uneven serial numbers) upwards - Green crates (even serial numbers) downwards The read-out data is also displayed in the top right-hand area of the screen. The bottom section of the screen has an integral RFID view, via which the currently read tag ID, the workplace used, the reader, the date and the time-of-day of the read operation, as well as the status description of the read tag, can be displayed. 2. Select the "Stop conveyor" button to stop the scenario. Click the "Back" button to display the start screen again: SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 21 Using the sample project 4.3 Using the project Outgoing goods The "Outbound log." button takes you to a screen that shows the functionality of outbound logistics: 22 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.3 Using the project 1. Choose between red and green crates/pallets using the selection fields next to the respective pallets. In this manner you specify whether even (green) tag IDs or odd (red) tag IDs are randomly generated. 2. The pallets can then be conveyed to an outgoing gate. Select the appropriate "Move pallet" button for this. At the top red outgoing gate, the reading procedure is automatically triggered by a light barrier. At the lower green outgoing gate, the reading procedure must be activated manually by clicking the "Read pallet" button. During the reading procedure, all the tags on the pallet are read out. The read data is supplied in the form of variables over the RFID data link. The tag IDs are evaluated in a script. - When a green pallet is located at the red gate of outbound logistics or vice-versa, a red Stop sign flashes after the read and the pallet is stopped. The number of incorrect tag IDs is displayed in the left-hand section of the screen. The pallet must then be manually returned to its initial position using the appropriate "Reset pallet" button. - If the pallet with its tag IDs is correct for the gate of outbound logistics, after reading it is pushed through the gate and loaded. The top section of the screen has an integral RFID view, via which the read tag read events, the data source used, the time of the read operation, as well as the status description of the read tag, can be displayed. The most recent read events are shown above. You can: - Delete events - Change the column sequence - Change the respective column width The buttons have the following functions: button Function Delete all events 1. Click the "Back" button to display the start screen again: The following settings in the simulator are used for simulation: SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 23 Using the sample project 4.3 Using the project The crate/pallet to be simulated is controlled via the selection fields and the associated Inport01 of the reader: Inport01 set to LOW ensures that the two top tag jobs are generated with odd tag IDs. Inport01 set to HIGH ensures that the two bottom tag jobs are generated with even tag IDs. The tag job with the number 4 represents 4 crates on the pallet and the other tag job represents the tag on the pallet. You can change the scenario by editing the number of crates or the tag IDs for the crates. 24 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.3 Using the project Configuration The "Configuration" button takes you to a screen in which changes can be made to the project configuration in Runtime: Individual components of the project can be re-parameterized via this screen. In the left window area, these components are visualized in the form of a tree structure. When individual components are selected, the associated parameters and their values appear in the right-hand window area. If you want to edit a value, click in the appropriate field and make the change. The status symbols in the tree structure have the following meaning: Symbol Description The components and their subcomponents are ready for operation The component and its subcomponents are not ready for operation The status of the components cannot be determined The components and their subcomponents are not in a uniform state You can: Edit the values of parameters Delete parameters SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 25 Using the sample project 4.3 Using the project Add parameters Change the column sequence Change the respective column width The buttons have the following functions: button Function Delete parameters Add parameters Open up the tree structure Activate changes to the project. The changes are not saved and will be lost when the runtime system is rebooted. It is generally recommended that the changes be simply activated and then the new project configuration tested. Activate and save changes to the project. Following a successful test, the changes can be saved. Only saved changes can be synchronized with the Engineering System. To prevent loss of data, note that all changes implemented subsequent to the last archived status will be saved. Undoing changes to the project. If a new project configuration results in errors, you can undo the changes. To prevent loss of data, note that all changes implemented subsequent to the last archived status will be undone. When you make changes to your project on the screen, save them and save them back to the Engineering System.

You will find further information regarding operator input in the documentation for the ALE+ client on the CD "SIMATIC RF-MANAGER 2008" under the path: "SIMATIC > RF-MANAGER 2008 Runtime > ALE+Client Demo\ ALE+ Function Manual.pdf". 5. Click the "X" button under the green start button to log off the ALE+ client from the RFMANAGER runtime system. Then you can close the ALE+ client. Every time the runtime system is restarted, the ALE+ client must be logged on to RFMANAGER runtime by pressing the green start button. 4.5 Connecting the project to the ALE interface In addition to the support for new RFID devices, the Service Pack also contains a further sample application to connect to the ALE interface of the RF-MANAGER. Functions This "ALEDataBridgeClient" can transform RFID data that was collected by the readers, processed by RF-MANAGER, and provided to the client via the ALE interface into a series of standard formats. CSV and XML formats are supported, as well as writing to an SQL database. The contents of the table can be defined via the client. The client is also supplied as binary file and in source code. In this way, it can also serve as a basis for custom applications. 30 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Using the sample project 4.5 Connecting the project to the ALE interface Figure 4-1 ALEDataBridgeClient The ALEDataBridgeClient is already fully installed following installation of the RF-MANAGER Service Pack, and it can be started via "SIMATIC > RFMANAGER 2008 Runtime > AleDataBridgeClient". This demo application is based on the ALE+ Client API Library and uses the ALE interface to make files available in .csv (text), .sql (database) and .xml (structured text) formats. The documentation for the ALEDataBridgeClient can be found in the folder, along with the source files. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 31 Using the sample project 4.5 Connecting the project to the ALE interface 32 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5 The following will familiarize you with the program interface of the Engineering System (ES) and the representation of the example project in the ES. The individual function blocks of the project are outlined and their mutual dependencies are presented. In addition, the fundamentals of configuring the most important screens are explained. 5.1 Programming interface of the engineering system You can access all the functions provided by the RF-MANAGER Engineering System by means of its menus and toolbars. When the mouse pointer is moved over an element, a tooltip appears. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 33 Project representation in the RF-MANAGER 5.1 Programming interface of the engineering system Elements of the program interface The RF-MANAGER Engineering System comprises the following elements: Elements of the RF-MANAGER Engineering System 1 Menus and toolbars The menus and toolbars provide access to all functions you need to configure your runtime system. When the corresponding editor is activated, menu commands and toolbars specific to that editor appear. When the mouse pointer is moved over a command, the corresponding ToolTip appears. 2 Project view All component parts and editors available in a project appear in a tree structure in the Project View. Folders are provided as sub-elements of each editor in which you can save objects in a structured way. With some editors, especially with the editor RFID Device, you have direct access to the configured objects. In the project window you have access to the device settings of the runtime system and the language settings. 3 Workplace Project objects are edited in the workplace. All RF-MANAGER elements are arranged on the borders of the workplace. With the exception of the workplace, you can organize, configure and, for example, move or hide any of the elements to suit your individual requirements. 4 Toolbox The Toolbox contains a selection of objects that you can add to your screens, e. g. image objects or operator control elements. 5 Properties dialog box The property dialog box is used to edit object properties, e. g. the color of screen objects. The properties dialog box is only available in specific editors. 34 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.2 RFID function blocks Elements of the RF-MANAGER Engineering System 6 Output view The output window displays system alarms generated, for example, in a project test run. 7 Object view The "Objects View" shows all elements of the area selected from the "Project View". Note With the exception of the workplace, you can show or hide all windows in the "View" menu. 5.2 RFID function blocks The individual RFID function blocks of the sample project are outlined below and their mutual dependencies are presented. This includes: RFID device Workplaces RFID data link ALE connections 5.2.1 RFID device The RFID device is a function block in RF-MANAGER and represents a reader. There are three RFID devices in the sample project. Reader "Reader_Labeling" (labeling): This reader reads and writes tag IDs. Reader "Reader_Sorting" (sorting): This reader reads tag IDs. The read results of the reader influence the setting of the separating filter. Reader "Reader_Gates" (outgoing goods): This reader reads tag IDs and thus monitors both outgoing goods gates. The configuring of the RFID devices can be traced using the editor "RFID Devices > (reader name)" in the properties dialog box. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 35 Project representation in the RF-MANAGER 5.2 RFID function blocks The following components are active in the relevant RFID device: Antennas The antennas read the data of the tags that are applied to the goods and pallets and transfer the data to the corresponding data source. The readers "Reader_Labeling" and "Reader_Sorting" use two antennas. The reader "Reader_Gates" uses all four antennas. The configuring of the antennas can be traced using the editor "RFID Devices > (reader name) > Antennas" in the properties dialog box. 36 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.2 RFID function blocks Data source Data sources are the basic components for reading RFID data. They enclose the antennas assigned to them and forward the data received via the antennas to the downstream function units. In general, one RFID device can contain several data sources. Different data sources can be defined so that mutually independent tasks can be performed with one reader (see online help Understanding and optimizing the acquisition of tags, chapter Multiple data sources). The readers "Reader_Labeling" and "Reader_Sorting" each comprise one data source with two assigned antennas. Two data sources are created in the reader "Reader_Gates" - one for each outgoing goods gate with two assigned antennas in each case. The configuring of the data sources can be traced using the editor "RFID Devices > (reader name) > Sources" in the properties dialog box; and the connection of data source and assigned antennas can be traced under "RFID Devices > (reader name) > Sources > General". One data source contains the following blocks: SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 37 Project representation in the RF-MANAGER 5.2 RFID function blocks Read trigger Read triggers are activation mechanisms. They cause the data source to read the data from the tags that are located in the antenna fields. For the readers "Reader_Labeling" and "Reader_Sorting", the triggers for the data sources are set to the edge of the I/O signal.. When the light barrier is interrupted, the input Inport00 of the reader is set which triggers a read. For the reader "Reader_Gates", the trigger for the automatic gate is also set to the edge of the I/O signal. The trigger for the manual gate is set to the application request because triggering is performed by the system function "ActivateTrigger". The configuring of the read trigger can be traced using the editor "RFID Devices > (reader name) > Trigger" in the properties dialog box. Triggers are assigned to data sources under "RFID Devices > (reader name) > Sources > Properties > Triggers". Tag selector Tag selectors are mechanisms used to route data on and to filter data. They determine which tag data areas should be read or routed on. They also define which tags should be supplied or filtered out on the basis of the contents of these data areas. In general, a tag selector orientates itself according to the tag ID or the freely parameterizable user data of the tag. Note No tag selector created in the sample project To keep the sample project as simple as possible, no tag selector has been created. Smoothing Smoothing is a technique that is used to optimize the read quality. The RF-MANAGER marks the read event with a status description for the tag (e.g.: detected by the antennas for the first time, detected with certainty, lost) and adds these states to the read results. Time intervals are defined using this technique - for example, how long a tag detected for the first time has to be "seen" for it to be regarded as reliably detected. This allows tags to be excluded that have been unintentionally detected briefly in the boundary areas of the reader. The configuring of the smoothing can be traced using the editor "RFID Devices > (reader name) > Sources > Properties > Smoothing" in the properties dialog box. Notification channel One or more data sources are assigned to one notification channel as data suppliers. In this scenario, three notification channels are used, one per reader. The notification channels route on the data from their data source. The configuring of the notification channels can be traced using the editor "RFID Devices > (reader name) > Notification channels" in the properties dialog box. 38 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.2 RFID function blocks One notification channel contains the following blocks: Notification channel trigger Notification channel triggers are activation mechanisms. They cause the notification channel to transfer the data from the data source assigned to it. In this project, continuous triggers are configured for all readers which ensure the continuous transfer of data. The configuring of the notification channel triggers can be traced using the editor "RFID Devices > (reader name) > Triggers" in the properties dialog box; and the connection of notification channels and assigned triggers can be traced under "RFID Devices > (reader name) > Notification channels > Properties > Triggers". Data selector Data selectors are mechanisms that process tag information and filter it. In this scenario, for example, filtering can be performed using filtering criteria that are defined in the data sources: Information is only transferred from tags that are in the reliably detected state. It can be assumed that these have been detected without errors. In general, the data selectors can supply additional information (reader fields). This includes, for example, the time of the read. The configuring of the data selectors can be traced using the editor "Selectors > Data selectors" in the properties dialog box. 5.2.2 Workplaces Workplaces are function blocks in the RF-MANAGER and are used to abstract the hardware. For this purpose, the relevant data sources and notification channels are grouped into workplaces. In practice, workplaces are combinations of readers. There are two workplaces in this example: One workplace refers to the reader "Reader_Labeling". This means that: This workplace stands for the labeling of tag IDs. The other workplace refers to the readers "Reader_Sorting" and "Reader_Gates". This means that: This workplace stands for sorting the goods and monitoring of the two outgoing goods gates. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 39 Project representation in the RF-MANAGER 5.2 RFID function blocks Is several readers are used per plant area, you can simplify the configuration by assigning several readers to one work area. Instead of selecting many readers in one RFID view, it is sufficient to select the encompassing workplace and you will obtain the data for all the associated readers. Note Additional synchronous data sources for Workplace_Labeling Additional synchronous data sources are configured for Workplace_Labeling, because it is only possible to write via workplaces and the data sources that they contain. The configuring of the workplaces can be traced using the editor of the same name in the properties dialog box. 5.2.3 RFID data link An RFID data link is used to supply read RFID data in variables. In the runtime system, the RFID data link registers with the workplaces, readers or data sources specified on configuring and receives the RFID data read there from this point onwards. 40 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.2 RFID function blocks The read RFID data is supplied in variables. This ensures that the data can be reliably evaluated in a PLC or with VB scripting in RF-MANAGER. The PLC can then trigger appropriate actions, for example, in production in accordance with the evaluation results. Through the use of variables, the data can be displayed in output fields in parallel. In the labeling scenario, the RFID data link "RFID_Data_link_Labeling" supplies the read tag ID in the form of a variable. The tag ID is supplied in raw hexadecimal format without a prefix. Only reliably detected tag IDs are required, so the event filter is set to observed. Coordination is not necessary in this scenario, because only one tag is in the field at a given time. In the sorting scenario, the RFID data link "RFID_Data_link_Sorting" supplies the read tag data and additional data, such as the acquisition time, to the PLC in the form of variables. The separating filters can be set for the conveyor belts via the PLC. The tag ID is supplied in tag format without a prefix. Only reliably detected tag IDs are required, so the event filter is set to observed. Coordination using an acknowledgement variable is appropriate in this scenario to ensure that the separating filter has been set. In the outbound logistics scenario, the RFID data link "RFID_Data_link_Gates" supplies the read tag IDs in the form of a variable. A script is used to check whether the tag data satisfies the previously specified requirements. The tag ID is supplied in raw hexadecimal format without a prefix. Only reliably detected tag IDs are required, so the event filter is set to observed. Coordination using an acknowledgement variable is appropriate in this scenario to ensure that all the read tag IDs are processed and checked in sequence. Data from more than one tag is usually read in one read procedure, so data is buffered in the RFID data link. The data is called in turn via a coordination mechanism, so it can be reliably evaluated. For further details on using the RFID data link, and especially on the coordination possibilities, please refer to the online help (Information System) for RF-MANAGER ES. The configuring of the RFID data link can be traced using the editor of the same name in the properties dialog box. 5.2.4 ALE connections The data of the workplaces can be requested in the form of reports by the enterprise system over the ALE interface (Application Level Events). When data are provided over the ALE interface, it is generally the case that ALE clients only have a logical view of the workplaces, precise knowledge of the hardware of the RFID system is no longer necessary. Note No user-defined ALE connection was created in the sample project To keep the sample project as simple as possible, no user-defined ALE connection has been created. A "Default ALE connection" is, however, always created automatically so that reports can be accessed. The data of a workplace can be requested in the form of reports by the enterprise system over the ALE interface (Application Level Events). The is performed using the following read procedure: SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 41 Project representation in the RF-MANAGER 5.3 Screens Asynchronous read procedure An asynchronous read procedure is when an ALE client of the enterprise system logs onto the report of the ALE interface and receives the data automatically. This continues until the client logs off again. Synchronous read procedure A synchronous read procedure is when an ALE client of the enterprise system logs onto the report of the ALE interface and receives the required data automatically. The data of an ALE report, however, are dependent on the activity of the following blocks: ALE selector ALE selectors are filter mechanisms that further reduce the accumulated data in accordance with the configuration settings. ALE selectors can only filter out EPC tags - to perform, for example, filtering according to article classes. Filtering of the freely parameterizable user data is not possible with ALE selectors - this must be performed via the data source or the notification channel. ALE groups ALE groups determine how the data records that have passed through the filter should be grouped for the report to the ALE client. The data records can be grouped according to serial numbers, for example. Note No ALE selector or no ALE group was created in the sample project To keep the sample project as simple as possible, no ALE selector and no ALE group were created. 5.3 Screens Screens are used to control RFID systems and their components. When you create your screens, the predefined objects support you in simulating your plant, displaying plant processes and defining plant values. You will find information in this chapter on the structure and component parts of the screens. 5.3.1 Scenario screens Below is an explanation of the screens that represent RFID functionalities in the sample project. This includes: Labeling Sorting Gates (outgoing goods) 42 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens 5.3.1.1 Basic settings and procedures When you view the scenario screens in the project tree in the "Screens" editor, you can trace the basic settings and procedures of the scenarios. In this chapter, the basic mechanisms are described first that are used in all scenario screens and which are therefore not described again later. Motion sequences In all scenario screens, the crates or pallets are moved with the help of a cyclically triggered script. You will find the scripts in the project tree in the "Scripts" editor. Scripts that are responsible for the movements have a name that starts with the name of the scenario and contains the component "Move" (e.g. Labelling_Move_...). The motion scripts are triggered by the variable "(scenario)_Cycle_100ms" that is incremented at intervals of 100 ms. This is performed by the system function "SimulateVariable". SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 43 Project representation in the RF-MANAGER 5.3 Screens 1. Click on the gray background in the respective scenario screen. In the properties window under "Events > Loaded", you will see the system function "SimulateVariable". The effect of this configuration at runtime is that the function is started after the screen has loaded and executes until the screen is exited. Note System function "SimulateVariable" can only be used to a limited extent The system function "SimulateVariable" can not be used with any type of trigger, because short update times and frequent use can cause excessive loading on the system. It should also only be used for simulation applications such as those described here. For cyclic triggering, a PLC variable is usually more suitable. As long as the function executes, the variable "(scenario)_Cycle_100ms" is incremented and triggers on every change of the event trigger "Change value" on the variable. 2. Open the "Variables" editor in the project window and select the variable "Labeling_Cycle_100ms". In the properties dialog box under "Events > Change value", you can see that the script "Labeling_Move_Conveyor" was configured on this trigger. 44 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens The result of this is that on every change in value of the variable "Labeling_Cycle_100ms" the system function "SimulateVariable" will call the script "Labeling_Move_Conveyor". In the script, depending on the position of the conveyor, different actions are performed that will be described in detail below. The basic principle of the motion sequences described applies to all scenario screens. Only the name part of the components for the scenario differs. Use of tags In the sample project, many different variables are used. An overview of the variables can be obtained by opening the "Variables" editor in the project view. To enable a variable to be quickly associated with the scenario, the name of the scenario precedes the variable name. All variables of the "Labeling" scenario are therefore called "Labeling_......". Most of the variables are internal variables, because the sample project executes without hardware. By using a simulator, it is, however, possible to use variables whose addresses are in the reader (e.g. inputs/outputs). One example is the "Labeling_Light_barrier" variable that starts the reading procedure when an input changes. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 45 Project representation in the RF-MANAGER 5.3 Screens In the "Sorting" scenario, variables are used whose addresses are located in the PLC "PLC_Sorting". One example is the variable "Sorting_ID" which provides the read tag ID for evaluation in the PLC. Online mode is deactivated for the PLC to enable the sample project to execute without a PLC. As a result, the PLC variables behave as internal variables to the runtime system. Variables are the most important components of the runtime system. They serve on the one hand to represent values from hardware modules, such as readers or PLCs, as well as to display and input values from the user. On the other hand, they also serve as triggers for actions within the runtime system. On a change in value or limit violation, system functions or scripts can be triggered to control and monitor a plant. You will find events and their actions in the properties dialog box under "Events". In the case described above, on a value change in the variable "Labeling_Serial_number", the script "Labeling_Modify_ID" is executed. The basic principle of triggering system functions or scripts on a change in value is used in many places in the sample project. 46 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens Use of screen objects As already described under the use of variables, actions in the form of system functions or scripts can also be triggered by screen objects. 1. Click a button in the screen, e.g. the button "Start conveyor" in the "Labeling" screen. In the properties window under "Events > Click", you can see that on clicking the button, the script "Labeling_Reset" is executed and the value of the variable "LabelingConveyorStatus" is set to 1. In this sample project, screen objects are frequently dynamized. Depending on the value of the variable, colors, operability, motion and visibility can be controlled. These mechanisms are used, for example, to lock buttons. 2. Click a button in the screen, e.g. the button "Start conveyor" in the "Labeling" screen. In the properties dialog box under "Animations > Enable object", you can see that the button will only be active when the variable "Labeling_Conveyor_Status" is set to 0. This means that when the scenario is started, the button is disabled. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 47 Project representation in the RF-MANAGER 5.3 Screens For further details on using animations, please refer to the online help (Information System) for RF-MANAGER ES. 5.3.1.2 Labeling The "Labeling" screen represents the functionality of the reader "Reader_Labeling" in the sample project. The central element here is the writing of tag IDs. This happens when the conveyor belt is automatically stopped - after the goods fitted with tags break the light barrier. The configuring of the "Labeling" screen can be traced using the editor "Screens / Labeling" in the properties dialog box. 48 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens Central sequence control is performed by the script "Labeling_Move_Conveyor", which is triggered cyclically as already explained by a change in the variable "Labeling_Cycle_100ms". Script Labeling_Move_Conveyor The script is used to control the movement sequences of the conveyor belt that can be influenced using the function keys "Start conveyor" and "Stop conveyor". The script is also responsible for stopping the conveyor belt automatically as soon as the goods fitted with a tag breaks the light barrier. Creation of the script can be traced using the editor "Scripts > Labeling_Move_Conveyor" in the properties dialog box. The script is structured as follows: Request: IF loop Description Labeling_Conveyor_Status = 1 You activate the scenario via the "Start conveyor" button. Labeling_Move_Status = 1 The conveyor will transport the crate 10 steps forwards until you stop the conveyor manually by resetting the variable "Labeling_Move_Status". The variable "Labeling_Move_Conveyor" determines the position on the conveyor. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 49 Project representation in the RF-MANAGER 5.3 Screens Request: IF loop Description Labeling_Move_Conveyor = 240 When the barrier is reached, the conveyor is stopped, because the variable "Labeling_Move_Status" is reset. At the same time the barrier is activated, due to the variable "Labeling_Light_barrier" being set that points to the input Inport00 in the reader "Reader_Labeling". The change to the input trips the edge-triggered read trigger of the reader "Reader_Labeling" that causes the data source to read out the tag ID. The "Write tag ID" button is switched to active. For the subsequent procedure, see "Workplace_Labeling" Labeling_Move_Conveyor = 300 When the crate leaves the light barrier again, the light barrier is switched inactive due to the variable "Labeling_Light_barrier" being reset. Labeling_Move_Conveyor = 500 As soon as the crate has reached the end of the conveyor, the scenario is started again. Workplace_Labeling The tag data that was read by the reader "Reader_Labeling" is supplied to the workplace "Workplace_Labeling" over the notification channel. This supplies the data to the enterprise system and also supplies it to "RFID_Data_link_Labeling". The configuring can be traced using the editor "Workplaces" in the properties dialog box. 50 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens The data source for synchronous data access must also be connected so that tag IDs can also be written by the reader "Reader_Labeling". This is performed in the properties dialog box under "Properties > Synchronous data access". RFID_Data_link_Labeling The RFID data link "RFID_Data_link_Labeling" was configured such that all the data of the workplace "Workplace_Labeling" and therefore of the reader "Reader_Labeling" is supplied in the variables "Labeling_Current_ID_Hex_Format". The configuring can be traced using the editor "RFID data link" in the properties dialog box. As only one tag ID can be in the field in this scenario, no coordination is necessary. You can see from the further properties which events and in which format the tag IDs are provided as a string. Labeling_Current_ID_Hex_Format This variable is linked to the script "Labeling_Modify_ID" which is called on a value change in "Split" mode. Script Labeling_Modify_ID At the beginning of the script, the read tag ID is converted from raw hex format to tag format using the system function "TranslateEpc". The subsequent procedure is in accordance with the mode on calling the script: With Split: The tag format is broken up into its components separated by dots. For SGTIN tag format, the serial number is in the final block. The serial number is assigned to the variable "Labeling_Serial_number". This variable is displayed in the screen as an input field and can be changed. If the value is changed by the user, this script is then called in the mode "Join". With Join: The components of the tag format are combined with a different serial number, if applicable, to form the new tag ID and the tag format is then translated back to the original hexadecimal format. This is necessary because the writing of tag IDs is only possible in hexadecimal format. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 51 Project representation in the RF-MANAGER 5.3 Screens Button for writing tag IDs This button is used to write the new tag ID. This is performed by the script "Labeling_Write"". The variable "Labeling_Move_Status" is then set so that the conveyor will start again. Script Labeling_Write The script "Labeling_Write" checks whether the ending of the tag ID is even or odd. For an odd serial number, "Labeling_Product_Type" is set to 1 which results in a red crate. For an even serial number, "Labeling_Product_Type" is set to 2 which results in a green crate. The tag ID is then written with the system function "WriteTagId". Writing can only be performed via a workplace for which a data source has been configured for the synchronous exchange of data. 5.3.1.3 Sorting The "Sorting" screen represents the functionality of the reader "Reader_Sorting" in the sample project. The core element here is the evaluation of tag read results in cooperation with an S7 PLC. The results are generated after the goods fitted with tags have broken the light barrier. The separating filter downstream of the conveyor belt is set according to the tag read results. The configuring of the "Sorting" screen can be traced using the editor "Screens > Sorting" in the properties dialog box. 52 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens Central sequence control is performed by the script "Sorting_Move_Conveyor", which is triggered cyclically as already explained by a change in the variable "Sorting_Cycle_100ms". Script Sorting_Move_Conveyor The script is used to control the movement sequences of the conveyor belt that can be influenced using the function keys "Start conveyor" and "Stop conveyor". The script is also responsible for an automatic read as soon as the goods fitted with a tag breaks the light barrier. Creation of the script can be traced using the editor "Scripts > Sorting_Move_Conveyor" in the properties dialog box. The script is structured as follows: Request: IF loop Description Sorting_Conveyor_Status = 1 You activate the scenario via the "Start conveyor" button. Sorting_Move_Status = 1 The conveyor will transport the crate 10 steps forwards until you stop the conveyor manually by resetting the variable "Sorting_Move_Status". The variable "Sorting_Move_Conveyor" determines the position on the conveyor. Sorting_Move_Conveyor = 100 When the barrier is reached, the light barrier is activated due to the variable "Sorting_Light_barrier" being set that points to the input Inport00 in the reader "Reader_Sorting". The change to the input trips the edge-triggered read trigger of the reader "Reader_Sorting" that causes the data source to read out the tag ID. For the subsequent procedure, see "RFID_Data_link_Sorting" Sorting_Move_Conveyor = 130 When the crate leaves the light barrier again, the light barrier is switched inactive due to the variable "Sorting_Light_barrier" being reset. Sorting_Move_Conveyor = 300 When the crate has reached the end of the fixed conveyor, depending on the product type "Sorting _Product_Type" recognized, a different movement path "Sorting_Direction" is activated. Red crates must move upwards to the red pallet. Green crates must move downwards to the green pallet. Sorting_Move_Conveyor = 600 As soon as the crate has reached the end of the conveyor, the scenario is started again. RFID_Data_link_Sorting The RFID data link "RFID_Data_link_Sorting" was configured such that all the data of the reader "Reader_Sorting" is supplied in several "Sorting_..." variables. The variables have addresses located in the PLC "PLC_Sorting" because in actual use, the data should be evaluated in the PLC. The values are also displayed in the top right-hand screen area in the form of output fields. The configuring can be traced using the editor "RFID data link" in the properties dialog box. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 53 Project representation in the RF-MANAGER 5.3 Screens In this scenario, several variables from one read procedure are supplied, so coordination is necessary. This is performed using the acknowledgement variable "Sorting_Quit_PLC". You can see from the further properties which events and in which format the tag IDs are provided as a string. For further details on using the RFID data link, and especially on the coordination possibilities, please refer to the online help (Information System) for RF-MANAGER ES. Sorting_Quit_PLC This variable is linked using the script "Sorting_PLC_Program" which is called every time that new data is signaled through the RFID data link "RFID_Data_link_Sorting". Script Sorting_PLC_Program The script "Sorting_PLC_Program" checks whether the ending of the currently supplied tag ID is even or odd. For an odd serial number, "Sorting_Product_Type" is set to 1 which results in a red crate. For an even serial number, "Sorting_Product_Type" is set to 2 which results in a green crate. The variable "Sorting_Product_Type" is used to determine the position of the separating filter which is implemented in the form of a graphical display. Finally, the acknowledgement variable "Sorting_Quit_PLC" is reset. When the acknowledgement variable is not reset, no new tags will be provided by the RFID data link. RFID view The tags present in the field are also displayed below the conveyor. The settings can be traced in the properties dialog box after the RFID display has been selected. To ensure that only the tags from the reader "Reader_Sorting" are displayed, an appropriate display selector "Display_selector_Sorting" has been configured. The configuring can be traced using the editor "Selectors" in the properties dialog box. 54 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens 5.3.1.4 Gates (outgoing goods) The "Gates" screen represents the functionality of the reader "Reader_Gates" in the sample project. The core element here is checking the pallets at the outgoing goods gate. To ensure that the right goods are delivered to the right customers, only red pallets are permitted to pass through the red outgoing gate and green pallets through the green outgoing gate. Incorrect pallets must be stopped. The configuring of the "Gates" screen can be traced using the editor "Screens > Gates" in the properties dialog box. Central sequence control is performed by the script "Gates_Move_Pallet", which is triggered cyclically as already explained by a change in the variable "Gates_Cycle_100ms". Symbolic I/O field for product selection In the left-hand area of the screen it is possible to select the products, and therefore the color of the pallets that will be moved through the respective gate, via two symbolic I/O fields (combination boxes). Using the text list "Product_Type_List", the value 1 (odd) is set for red crates and the value 2 (even) is set for green crates. The values of the variables "Gates_Product_Type_Red_Pallet" or "Gates_Product_Type_Green_Pallet" are then evaluated in the script "Gates_Move_Pallet". SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 55 Project representation in the RF-MANAGER 5.3 Screens Script Gates_Move_Pallet The script is used to control the movement sequences of the pallets that can be started using the "Move pallet" buttons. The script is also responsible for an automatic read as soon as the goods fitted with a tag breaks the light barrier on the red outgoing gate. Creation of the script can be traced using the editor "Scripts > Gates_Move_Pallet" in the properties dialog box. The script is structured as follows: For the red outgoing gate ("Gates_Gate_Type"=1) in automatic mode with the light barrier: Request: IF loop Description Gates_Conveyor_Status = 1 You activate the scenario via the appropriate "Move pallet" button. Gates_Move_Status = 1 The pallet will move 10 steps forwards until you stop the motion manually by resetting the variable "Gates_Move_Status". The variable "Gates_Move_Red_Pallet" determines the position in the path. Gates_Move_Red_Pallet = 20 The color set for the pallet above is evaluated. Depending on the value of the variable "Gates_Product_Type_Red_Pallet", a temporary variable "Gates_Product_Type_Simulation" is set, that will set the input Inport01 on the reader "Reader_Gates" for simulation of the tag IDs to LOW (odd tag IDs) or HIGH (even tag IDs). Please refer to the description in the section "Using the project > Outbound logistics screen > Settings in the simulator". Gates_Move_Red_Pallet = 120 When the barrier is reached, the light barrier is activated due to the variable "Gates_Light_barrier_Red_Gate" being set that points to the input Inport00 in the reader "Reader_Gates". The change to the input trips the edge-triggered read trigger of the reader "Reader_Gates" that causes the data source to read out the tag ID. For the subsequent procedure and checking the read tag IDs, see "RFID_Data_link_Gates" Gates_Move_Red_Pallet = 200 When the pallet leaves the light barrier again, the light barrier is switched inactive due to the variable "Gates_Light_barrier_Red_Gate" being reset. The check for detection of invalid tag IDs ("Gates_Wrong_Red_Tags" > 0) is performed simultaneously. If the wrong tag IDs were detected, movement of the pallets will be stopped. In this case, an acknowledgement is required via the relevant "Reset pallet" button. Gates_Move_Red_Pallet = 450 If the pallet was not stopped, at the end of the motion path, the scenario is started again. For the green outgoing gate ("Gates_Gate_Type"=2) in manual read mode: Request: IF loop Description Gates_Conveyor_Status = 1 You activate the scenario via the appropriate "Move pallet" button. Gates_Move_Status = 1 The pallet will move 10 steps forwards until you stop the motion manually by resetting the variable "Gates_Move_Status". The variable "Gates_Move_Green_Pallet" determines the position in the path. 56 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens Request: IF loop Description Gates_Move_Green_Pallet = 20 The color set for the pallet above is evaluated. Depending on the value of the variable "Gates_Product_Type_Green_Pallet", a temporary variable "Gates_Product_Type_Simulation" is set, that will set the input Inport01 on the reader "Reader_Gates" for simulation of the tag IDs to LOW (odd tag IDs) or HIGH (even tag IDs). Please refer to the description in the section "Using the project > Outbound logistics screen > Settings in the simulator". Gates_Move_Green_Pallet = 150 When the position is reached, the movement is stopped by resetting the variable "Gates_Move_Status" and the "Read pallet" button is activated for manual reading. The system function "ActivateTrigger" and setting of the variable "Gates_Move_Status" is configured at the "Read pallet" button for the purpose of resuming the movement. The system function call "ActivateTrigger" with reference to the trigger "SourceTrigger_AppRequest" trips the read trigger of the reader "Reader_Gates" set to the application request, which in turn causes the data source to read out the tag IDs. For the subsequent procedure and checking the read tag IDs, see "RFID_Data_link_Gates" Gates_Move_Green_Pallet = 200 The check for detection of invalid tag IDs ("Gates_Wrong_Green_Tags" > 0) is performed when the pallet leaves the outgoing gate following the manual read. If the wrong tag IDs were detected, movement of the pallets will be stopped. In this case, an acknowledgement is required via the relevant "Reset pallet" button. Gates_Move_Green_Pallet = 450 If the pallet was not stopped, at the end of the motion path, the scenario is started again. RFID-Data_link_Gates The RFID data link "RFID_Data_link_Gates" was configured such that the read tag IDs of the reader "Reader_Gates" is supplied in the variable "Gates_ID". More than one tag ID is detected during the read procedure, so the tag IDs are supplied in sequence for evaluation. They are supplied in sequence by means of coordination using the acknowledgement variable "Gates_Quit_Script". Evaluation with a subsequent acknowledgement is performed in the script "Gates_Script_Program". The configuring can be traced using the editor "RFID data link" in the properties dialog box. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 57 Project representation in the RF-MANAGER 5.3 Screens You can see from the further properties which events and in which format the tag IDs are provided as a string. For further details on using the RFID data link, and especially on the coordination possibilities, please refer to the online help (Information System) for RF-MANAGER ES. The read tag events are also displayed in the top section of the screen in the form of an RFID view. Gates_Quit_Script This variable is linked using the script "Gates_PLC_Program" which is called every time that new data is signaled through the RFID data link "RFID_Data_link_Gates". Script Gates_Script_Program The script "Gates_Script_Program" is executed when the RFID data link signaled through the variable "Gates_Quit_Script" that a valid value was written to the variable "Gates_ID". Depending on the outgoing gate at which the check was made, At the red gate ("Gates_Gate_Type"=1) for an even serial number (green tag IDs) the variable "Gates_Wrong_Red_Tags" will be increased by 1. At the green gate ("Gates_Gate_Type"=2) for an odd serial number (red tag IDs) the variable "Gates_Wrong_Green_Tags" will be increased by 1. Several tag IDs were acquired during one read procedure and the values in the RFID data link were buffered, so the acknowledgement variable "Gates_Quit_Script" is reset following evaluation of the first tag ID. This ensures that the RFID data link supplies the next tag ID and all read tag IDs are read in the manner described above. The movement in the script "Gates_Move_Pallet" continues during the check, so the results are evaluated and subsequent actions are activated as described above in the script from position 200. RFID view The read tag events are also displayed above the outgoing gates. The settings can be traced in the properties dialog box after the RFID display has been selected. To ensure that only the tag events from the reader "Reader_Gates" are displayed, an appropriate display selector "Display_selector_Gates" has been configured. The configuring can be traced using the editor "Selectors" in the properties dialog box. 5.3.2 System screens Below is an explanation of the screens that present system information in the sample project. This includes: Configuration Alarms 58 SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens 5.3.2.1 Configuration The "Configuration" screen visualizes the configuration of the sample project. Configuration changes can be made via this screen in Runtime. The screen is thus used for starting up and optimizing the RFID system. Individual components can be reparameterized here. Individual parameters can also be deleted. The configuring of the "Configuration" screen can be traced using the editor "Screens > Configuration" in the properties dialog box. The screen mainly comprises the screen element "Configuration" in the "Standard" view (RFMANAGER ES). The poll cycle can be parameterized to specify an update interval for the view. 5.3.2.2 Alarms Below is an explanation of the functions that are used for further diagnostics in the sample project. This includes: The "Alarms" screen Alarm window SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 59 Project representation in the RF-MANAGER 5.3 Screens Alarms screen The "Alarms" screen is used to display the alarm events that have been triggered. The configuring of the "Alarms" screen can be traced using the editor "Screens > Alarms" in the properties dialog box. The screen mainly comprises the screen element "Alarm view". It is specified in the properties dialog box under "General" that alarm events and all alarm classes (except for RFID_Debug) should be displayed. The parameters visualized in the alarm view are specified in the properties dialog box under "Properties > Columns". The following parameters are available: 60 Parameters Description Alarm number The alarm number is used to reference an alarm. Time The time-of-day of receipt of the alarm Status Status description of the alarm: "Activated", "Acknowledged" or "Deactivated" Alarm text The alarm text contains a description of the alarm. Alarm class The alarm classes mainly determine how alarms will appear when they are displayed on the Runtime system. Alarm classes are also used to group alarms for various means of display. RF-MANAGER has both predefined alarm classes and the option to configure user-defined alarm classes. SIMATIC RF-MANAGER 2008 Getting Started, 06/2010, A5E01070047-03 Project representation in the RF-MANAGER 5.3 Screens Parameters Description Date The date of receipt of the alarm Device (fault location) Alarm trigger A button is also configured with the system function "ClearAlarmBuffer". To trace the settings, click the button and navigate through the properties dialog. You will find the system function under "Events > Click". Alarm window During operation of the sample project, the "alarm window" visualizes incoming alarms and the associated additional information. The alarm window cannot be selected via a button, but appears automatically at each alarm event regardless of the screen. The layout and operation of the alarm window correspond to that of the alarm view. The configuring of the alarm window can be traced using the editor "Screens > Template" in the properties dialog box. It is specified in the properties dialog box under "General" that active alarms should be displayed. Only the critical alarm classes and system alarms are displayed.
