The M4RTU/M4IO is built to be deployed in any type of network or remote control environment. The M4RTU/M4IO was designed specifically for industrial field applications, such as wastewater treatment, well monitoring, tank farms, substation automation, and gas/petrochemical applications. The M4RTU/M4IO is fully supported with FactoryFloor, Opto 22's legacy suite of WindowsTM software for industrial automation customers. FactoryFloor consists of four integrated components: * OptoControlTM, a graphical, flowchart-based development environment for control solutions * OptoDisplayTM, a graphical, multimedia operator interface package * OptoServerTM, a data server that connects the controller network with the PC-based FactoryFloor network * Plus OptoConnectTM, a drag-and-drop database utility The M4RTU/M4IO is part of Opto 22's Modular line of controllers. These units feature a modular design that incorporates Opto 22's M4 bus technology (M4BUS). This technology lets customers tailor their controller and interface hardware to the scale of the project at hand. The M4BUS allows users to create custom interface configurations by simply plugging in one or more of the modular interface cards. These open options allow customers to share real-time plant floor data with telemetry or network-based control and information systems. All modular interface cards for serial communications or network connectivity are supported as standard selections in the FactoryFloor software. The M4RTU/M4IO consolidates two processors on a single processor board. Program control and host communications are handled by a 32-bit 68020 microprocessor, while a 16-bit 80C196 processor handles I/O interfacing and control. This dual-processor board is combined with a digital/analog I/O board, a 3-slot vertical expansion bus board (M4BUS), and a modular power supply into a compact aluminum extrusion package that can be mounted horizontally or vertically. M4RTU/M4IO User's Guide 33 OVERVIEW--M4RTU/M4IO REMOTE TELEMETRY UNIT The M4RTU/M4IO base unit has two serial ports: RS-232 and RS-485/422. The RS-485/422 port can be used to support I/O expansion using standard Opto 22 digital or analog I/O units. These serial ports can communicate at up to 115 K baud, and the RS-485/422 port logically supports up to 4,096 remote I/O channels as a remote bus. The M4RTU/M4IO comes standard with 1 MB of battery-backed RAM and 256 KB of flash memory. The RAM can be used to store a user's control strategy (program) and data. The flash memory stores firmware (an operating system, sometimes called a kernel) and can be used to store a user's control strategy permanently. The use of flash technology throughout the M4RTU/M4IO allows the user to remotely download new firmwares offered by Opto 22. This avoids the need to visit an M4RTU/M4IO site to download new firmware that offers features required for a given application. The M4RTU/M4IO base unit accommodates a total of eight digital and four analog Generation 4(R) (G4) I/O modules. The G4 digital I/O modules provide optical isolation, come in a variety of DC and AC voltages, feature an integral status LED as well as fused outputs, and offer an optional integral automatic/manual diagnostic switch. The G4 analog I/O modules provide both optical and transformer isolation, eliminating ground loops and channel-to-channel interference. Analog modules come in a variety of field input and output types, including current loop, voltage, thermocouple, RTD, ICTD, and TPOs. Analog current modules include the option to power the current loop, eliminating costly power supplies and wiring. For safety and convenience, the M4RTU/M4IO has system monitors for temperature, AC operation, and low battery, and includes such features as a real-time clock and watchdog timers. Removable connector technology is integrated throughout the unit for easy maintenance and wiring removal. Expansion options are available for adding I/O channels as well as for communicating with SCADA systems, industrial PCs, other controllers or intelligent equipment devices. Available Options The M4RTU/M4IO accommodates eight digital and four analog G4 I/O modules. For applications requiring additional I/O modules, the Modular Controller product line includes a Modular Controller I/O Extender, called the M4RTUX, which connects to the M4RTU/M4IO base unit using an Opto 22 shielded 25-pin M4RTUXCAB cable. The M4RTUX provides an additional eight digital and four analog I/O channels. With the M4RTUX option connected to the M4RTU/M4IO base unit, up to 24 G4 I/O modules can be installed. Additional I/O can be connected via an RS-485 serial link. To accommodate a wide variety of applications, seven power supplies are available for the M4RTU/M4IO: four wide-input-range DC (12V, 24V, 48V, 125V), two wide-input-range AC (120V, 220V), and one line filter base for connecting user-supplied power supplies. These fuse-protected power supplies feature input-to-output isolation protection, a built-in EMI filter, and an on/off switch. They supply enough power to operate the M4RTU/M4IO base unit, three M4BUS expansion options, and I/O modules for both the base unit and the Modular M4 Controller I/O Extender. They can also supply the current loop for analog current modules. The M4BUS technology provides a variety of communication interface cards. M4RTU/M4IO options include an Ethernet interface card (M4SENET-100), an ARCNET(R) interface card (M4SARC), a serial (RS-232 and RS-422/RS-485) interface card (M4SSER), a fiber optic ARCNET(R)card (M4SARCF) and a fiber optic ARCNET(R) repeater card (M4SARCFR). These open options allow customers to share 4 M4RTU/M4IO User's Guide CHAPTER 1: INTRODUCTION real-time data with telemetry-based SCADA systems or network-based control and information systems. The available serial ports communicate at up to 115 K baud. These ports can be used to support additional I/O units, perform host communications, interface to a modem or transmit data to and from third-party devices. The Ethernet and ARCNET options enable you to connect the M4RTU/M4IO to other major system components using plantwide information networks. All modular interface cards for serial communications or network connectivity are supported as standard selections in the FactoryFloor software. Software M4RTU/M4IO configuration and program development are performed on a PC workstation through OptoControl, Opto 22's PC-based graphical flowchart language. OptoControl is easy to learn and easy to use. Six months after you write an OptoControl program, you can come back to it and understand it. Four key features of OptoControl are: * OptoControl's flowchart programming environment, which provides a precise, graphical view of your control process. * OptoControl's "Strategy Tree," which provides a tree-like view of your system configuration. * OptoControl's animated debugger, which makes it easy to step through your process and see what's happening at every point in your control program. * OptoControl flowcharts, which can be packaged as subroutines to provide extensive code reusability. All these tools can be live on your workstation at the same time. OptoControl uses a plain English command set and a long tagname database that is shared by all FactoryFloor components. During development of your application, you can download your control strategy to the M4RTU/M4IO and debug the program using OptoControl debug mode. OptoDisplay, Opto 22's operator interface package, uses the same long-tagname database generated by OptoControl when you develop a graphical display of your process. OptoControl's built-in Software Developers Kit (SDK) allows custom software developers a direct interface to Opto 22 controllers from high level programming languages. OptoControl also provides open access to the database for third-parties and custom developers through the use of OptoServer. Using OptoServer, the data server that connects the controller network with the PC-based FactoryFloor network, you can develop client/server architectures supporting any DDE or OPC aware third-party applications. The FactoryFloor software environment supports modems (direct, lease, and radio), two-way dial-up capability (host to M4RTU/M4IO, M4RTU/M4IO to host), and peer-to-peer communications. It also supports remote firmware (kernel) downloading to flash memory, remote program downloading and debugging, and remote data uploading and downloading. M4RTU/M4IO User's Guide 55 POSSIBLE APPLICATIONS Possible Applications The M4RTU/M4IO can be used in a wide range of applications, including SCADA, remote, distributive, stand alone, process control, tooling, communication, data acquisition, and OEM applications. The following diagrams depict two common applications for the M4RTU/M4IO: a tank farm and a remote plant management system. Both applications typically require process control and data acquisition to be performed remotely. Tank Farm Remote Plant Management 6 M4RTU/M4IO User's Guide CHAPTER 1: INTRODUCTION The M4RTU/M4IO is designed to be easy to configure in a variety of communication configurations, including modems connected to standard telephone lines, leased lines, radio frequency transceivers, and direct serial connections to PC hardware, as illustrated below. M4RTU/M4IO User's Guide 77 POSSIBLE APPLICATIONS The design of the M4RTU/M4IO is also conducive to integration with Opto 22's digital and analog I/O systems as well as with other intelligent equipment devices, such as industrial PCs, additional M4RTUs or other Opto 22 controllers, subsystem automation gear, wastewater equipment, and various gas/petrochemical devices. Integration of M4RTU/M4IO with Expanded I/O Integration of M4RTU/M4IO with Other Devices 8 M4RTU/M4IO User's Guide CHAPTER 1: INTRODUCTION Basic Architecture The M4RTU/M4IO consolidates two processors on a single processor board. Program control and host communications are handled by a 32-bit 68020 microprocessor, while a 16-bit 80C 196 processor handles I/O interfacing and control. This dual-processor board is combined with a digital/analog I/O board, a 3-slot vertical expansion bus board (M4BUS), and a modular power supply into a compact aluminum extrusion package that can be mounted horizontally or vertically. A block diagram of the M4RTU/M4IO is shown below. The two-processor architecture allows the main processor to off-load onto the I/O processor such tasks as counting, frequency and pulse measurement, latching, totalizing, time proportional output control, pulse generation, linearization, ramping, engineering unit conversion, averaging, peak and valley measurement, PID control, and event/reactions, to name a few. I/O control can continue even if the main processor fails or needs to be reset. Sophisticated reset circuitry and watchdog timer capability permit a user to develop intelligent, robust error recovery. Finally, the M4BUS lays the foundation for intelligent coprocessor daughter cards, which have the capability to interface to various industry hardware and software protocols without degrading overall real-time performance.

When the jumper is in (the default), the control program will run from RAM; when the jumper is out, the control program is copied from Flash EEPROM into RAM and run from RAM. Normally, application programs are downloaded from your PC workstation to battery-backed CMOS RAM in the M4RTU/M4IO. The programs are then executed from RAM. Unless application programs are stored in Flash EEPROM, the E/R jumper should be installed to allow the control program in RAM to run. Autoboot Jumper (AUTO) Use this jumper to determine whether autoboot mode will be enabled (jumper in) or disabled (jumper out, the default). When autoboot mode is enabled, at power-up the M4RTU/M4IO automatically executes the resident user program (RAM or Flash). Otherwise, it waits to receive a command to run the resident program. Communication Mode Jumper (X0) Use this jumper to select whether communication between the host computer and the controller will be in binary mode (jumper in, the default) or ASCII mode (jumper out). Generally, ASCII mode is used in applications requiring a modem. For ARCNET or Ethernet this jumper is ignored. For more detailed information, refer to the OptoControl Command Reference Manual -- Communications Overview. Boot Loader Jumper (X1) Use this jumper to set the controller to either boot to the downloaded firmware, or kernel (jumper in, the default) or boot to loader (jumper out). This jumper should always remain in place for normal operations. See Appendix A, "Troubleshooting," for more information. Host Port Jumpers (H0, H1) Use these jumpers to determine the primary host port used by the M4RTU/M4IO upon power-up or reset. Select from COM0 (both jumpers in, the default), COM1 (H0 jumper out, H1 jumper in), ARCNET (H0 jumper in, H1 jumper out), or Ethernet (both jumpers out). COM0 is dedicated for RS-232 communications and COM1 is dedicated for RS-485 communications. Select ARCNET only if an optional M4SARC, M4SARCF, or M4SARCFR ARCNET expansion card is installed. Select Ethernet only if an optional M4SENET-100 expansion card is installed. Baud Rate Jumpers (BAUD 0-3) Use these jumpers to set the baud rate for the host serial port (COM0 or COM1) on power-up or reset. Select the appropriate jumper settings based on the baud rates in Table 3-2. (These baud rates also appear on the sticker on the underside of the M4RTU/M4IO's top cover.) The default baud rate is 38.4 Kbps. Note that if an optional ARCNET or Ethernet expansion card is installed and ARCNET or Ethernet is configured as the host, the baud rate jumper settings are irrelevant. 26 M4RTU/M4IO User's Guide CHAPTER 3: INSTALLATION AND SETUP Use the Configure Controllers - Setup Controller Ports dialog box in OptoControl to set the baud rate for any M4RTU/M4IO serial port that is not being used as the primary host port. Consult the OptoControl User's Guide for more information. Address Jumpers (ADDRESS 0-7) Use these jumpers to select an 8-bit address from one to 255 (one to FF hexadecimal). The factory default is one (jumper zero in, all others out). The most significant bit is seven and the least significant bit is zero; address zero is reserved and should not used. The following diagram shows the jumper configurations for all addresses. Ring Indicator Jumper (JP1 ) NOTE: For newer M4RTU/M4IO base units only, which are identified by a Rev. 2 sticker on the unit. If you have a Rev. 1 base unit, see the next section,"Processor Board Jumpers for Rev. 1 Units" . By default, this jumper is installed, establishing a ground on COM0 Pin 7 of the M4RTU/M4IO base unit. The jumper should remain installed under most circumstances. For the location of JP1, see the illustration below. If you need an extra programmable RS-232 input (such as a ring indicator), remove this jumper. Since this will eliminate the ground on COM0, it will be necessary to wire your RS-232 device ground to COM1 Pin 3 to prevent common mode problems and resulting damage. M4RTU/M4IO User's Guide 27 27 SETTING CONFIGURATION JUMPERS AND SWITCHES Ring indicator selection jumper on Rev. 2 board (JP1) Rev. 2 M4RTU/M4IO Processor Board Jumpers for Rev. 1 Units NOTE: For earlier M4RTU/M4IO base units only. For Rev. 2 units, see the previous section, "Ring Indicator Jumper (JP1 )" . Four additional jumpers are located on the main processor board, as shown below. The following table describes the use and default settings of all jumpers for Rev. 1 M4RTU/M4IO base units. When a jumper is installed, the setting corresponding to the In position is in effect. When a jumper is not installed, the setting corresponding to the Out position is in effect. The factory defaults are indicated in bold.

Flash Jumpers (FL) FL identifies the TYPE of firmware EPROMS (either FLASH or UV EPROMS). FL removed indicates FLASH EPROMS. FL installed indicates UV EPROMS. The default setting is for this jumper to be removed. All M4RTU/M4 I/O controllers have FLASH EPROMS, so this jumper should NEVER be installed. *RAM Jumper (MJ) MJ identifies the AMOUNT of RAM installed (and hence the TYPE of RAM chips). MJ installed indicates 256 KB (Kbytes) which is in the form of 2 chips that are 1 megabit each. MJ removed indicates 1 MB (megabyte) which is in the form of 2 chips that are 4 megabits each. If the M4RTU/M4 I/O has a "1 MB RAM Installed" sticker, the default setting is for this jumper to be removed. If the M4RTU/M4 I/O does not have this sticker, the default setting is for this jumper to be installed. ROM Jumper (RJ) RJ identifies the AMOUNT of EPROM memory installed (and hence the TYPE of EPROM chips) or vice versa. RJ installed indicates 256 KB (Kbytes) which is in the form of 2 chips that are 1 megabit each. RJ removed indicates 1 MB (megabyte) which is in the form of 2 chips that are 4 megabits each. The default setting is for this jumper to be installed. Ring Indicator Jumper (JP2 ) By default, this jumper is installed, establishing a ground on COM0 Pin 7 of the M4RTU/M4 I/O base unit. The jumper should remain installed under most circumstances. If you need an extra programmable RS-232 input (such as a ring indicator), remove this jumper. Since this will eliminate the ground on COM0, it will be necessary to wire your RS-232 device ground to COM1 Pin 3 to prevent common mode problems and resulting damage. M4RTU/M4IO User's Guide 29 29 CONNECTING FIELD WIRING Serial Port Switches (COM1) The M4RTU/M4IO base unit comes standard with one RS-485 serial port COM1. This port includes configuration switches. The following diagram shows the serial port COM1 switches as they appear on the end cap of the M4RTU/M4IO. See below for details on configuring these switches. TERM IN/TERM OUT This switch selects termination for the RS-485 port. In the IN position, the RS-485 lines are terminated and biased. Terminate the port when it is physically the first or last unit in an RS-485 multi-drop serial network application. In the OUT position, the RS-485 lines will be floating. This setting should be used when the port is part of a multi-drop serial network application and is not physically the first or last unit in the network. The default is TERM IN. 2-WIRE/4-WIRE This switch selects the wiring method used to connect to the RS-485 serial port. The choices are 2-wire and 4-wire. The default is 4-wire. If you are using COM1 as an RS-485 serial link (remote), select 2-wire mode. Connecting Field Wiring To access the field wiring terminals, you will first need to remove the top cover of the M4RTU/M4IO by removing the four corner screws at the top of the unit. The pluggable field wiring terminals are located on the top of the M4RTU/M4IO board next to the corresponding digital or analog channels. These terminals allow field wires to be connected to the installed I/O modules. The following diagram shows the location of the terminals on the unit and the layout of the terminal points as they correspond to each I/O module. Specific information on wiring digital and analog modules follows. For more detailed wiring information, refer to Chapter 5, "Field Wiring,"on page 45. 30 M4RTU/M4IO User's Guide CHAPTER 3: INSTALLATION AND SETUP Digital Modules Digital modules have two terminals corresponding to each module. The following diagram shows a G4IDC5 digital input module in channel zero wired with VIN + on terminal #1 and VIN - on terminal #2. M4RTU/M4IO User's Guide 31 31 CONNECTING TO A HOST PC OR MODEM Analog Modules Analog modules can use up to four terminals per I/O point. The following diagram shows a G4AD6 0-5 VDC analog input module in channel zero wired with VIN - on terminal #2 and VIN + on terminal #4. Refer to page 50 for wiring other analog modules. Connecting to a Host PC or Modem The M4RTU/M4IO features two built-in serial ports, COM0 (RS-232) and COM1 (RS-485), with a data transfer rate of 300 Bd to 115.2 Kbps. Two additional serial ports are available by installing an optional M4SSER serial expansion card into one of the M4RTU/M4IO expansion card slots. IMPORTANT: Serial port connectors wired for other Opto 22 controllers may not be compatible with the M4RTU/M4IO. Use the M4RTU/M4IO connectors provided and refer to the diagrams in this manual for wiring information. The following sections describe wiring for the serial ports found on the M4RTU/M4IO base unit. 32 M4RTU/M4IO User's Guide CHAPTER 3: INSTALLATION AND SETUP RS-232 COM0 Pin Connections The M4RTU/M4IO has one built-in RS-232 COM0 serial port.The following table describes COM0 pins. Pin COM0 1 Data Carrier Detect (DCD) 2 Transmit (TX) 3 Receive (RX) 4 Request-to-Send (RTS) 5 Clear-to-Send (CTS) 6 Data Terminal Ready (DTR) 7 Ground (GND) IMPORTANT: If RTS and CTS are not used, RTS must be connected to CTS (COM0 only) on the M4RTU/M4IO. RS-485 COM1 Pin Connections An RS-485 COM1 port is also built into the M4RTU/M4IO base unit. The following table contains descriptions for each COM1 pin for both 2-wire and 4-wire modes. Note that the interrupt lines can be used to add interrupt capability to Opto 22 I/O units connected to an M4RTU/M4IO via an RS-485 serial link (remote).

Examples show connections to a standard PC serial port and an Opto 22 AC37. Be sure to use cable appropriate to your application. See Appendix B, "Cable and Connector Specifications," for a complete list of recommended cables. M4RTU/M4IO User's Guide 33 33 CONNECTING TO A HOST PC OR MODEM RS-232 COM0 Make RS-232 communication connections to a host PC by using the RS-232 COM0 default host connector on the M4RTU/M4IO. The following diagram shows how to connect the M4RTU/M4IO to the serial port of a host PC. Verify that the pin connections at the host PC are the same as those called out in the diagram. Important: If RTS and CTS are not used, RTS must be connected to CTS (COM0 only) on the M4RTU/M4IO, as shown below. RS-485 COM1 4-Wire Mode Using an AC37. If you are using an Opto 22 AC37, connect the end of the cable with a male 9-pin D-shell connector to the converter and the other end with a pluggable terminal block to the M4RTU/M4IO. The following diagram shows how to wire to a host PC in 4-wire mode using an AC37. 34 M4RTU/M4IO User's Guide CHAPTER 3: INSTALLATION AND SETUP 2-Wire Mode Using an AC37. The AC37 also supports a 2-wire mode. See the following diagram for wiring. Wiring to a Modem (a DCE device) Refer to your modem documentation for detailed wiring information, possible jumper configuration, and initialization setup. Most standard external PC modems can be usd with the M4RTU/M4IO. However, a custom (or special) communications cable must be used between the modem and the M4RTU/M4IO. Wiring diagrams for this cable are shown below.

A M4SSER serial expansion card installed in the M4RTU/M4IO can also be used for this purpose. One method for doing this is to use a Mistic 200 I/O Remote Interface board (G4IOR) as illustrated below. This method allows the use of Opto 22 I/O equipment (G4 panels, cables, etc.). This diagram shows a 2-wire RS-485 shielded connection from COM1 on the M4RTU/M4IO to the G4IOR Remote Interface board. Connect Pin 1 (TX/RX+) to G4IOR "TH+," Pin 2 (TX/RX-) to G4IOR "TH-," and Pin 3 to "COM." If you are using the interrupt lines, connect Pin 6 to "IRQ+" and Pin 7 to "IRQ-." M4RTU/M4IO User's Guide 37 37 CONNECTING TO OPTO 22 I/O UNITS Communications to a Remote Interface (G4IOR) Another method for using the RS-485 COM1 port as an RS-485 serial link (remote) is to use Opto 22 I/O units installed with an SBTA, as illustrated in the following diagram. This allows you to accommodate your own installation practices, application requirements, and cables. Simply mount your I/O units throughout your installation and daisy chain communication cable between them. Refer to the Mistic 200 Systems Installation Guide for more SBTA details. 38 M4RTU/M4IO User's Guide CHAPTER 3: INSTALLATION AND SETUP Opto 22 I/O Units Installed with SBTA LED Indicators Five LEDs are located on the top of the M4RTU/M4IO, in line with the configuration jumpers, as shown below.

M4RTU/M4IO User's Guide 4: Chapter 4 Software and Firmware Overview This chapter provides information on using OptoControl, OptoDisplay, and OptoServer with the M4RTU/M4IO. OptoControl is used to program and debug M4RTU/M4IO control strategies. OptoDisplay is used to create M4RTU/M4IO process operator interfaces running on the PC. OptoServer allows the user to construct complex client/server architectures running multiple OptoDisplay sessions, DDE-aware applications (such as Microsoft Excel), or third-party software packages with OptoServer driver capability. The tight integration between OptoControl, OptoDisplay, and OptoServer not only makes all three software packages easy to use, it also prevents multiple database entry errors, allows tag name validation, and takes full advantage of the M4RTU/M4IO's hardware capabilities. The sophisticated firmware of both the main and I/O processors of the M4RTU/M4IO, along with flash technology, enables a user to update the M4RTU/M4IO remotely with a new set of operating systems for the main and I/O processors. The firmware also supports the ability to store a user's strategy permanently into flash memory. Note: It is not the intent of this chapter to teach OptoControl programming and debugging, OptoDisplay configuration and runtime operation, or overall OptoServer usage. Instead, this chapter presents an overview of these topics, with enough details to get you started. For detailed information on these subjects, refer to the appropriate Opto 22 user guides. OptoControl OptoControl is used to configure communications between the PC and the M4RTU/M4IO, configure the I/O units and points, and develop and run your control strategy. Configuring Communications to the M4RTU/M4IO To download OptoControl strategies to the M4RTU/M4IO and debug them, you must first configure the communication link between the host PC and the M4RTU/M4IO. Begin by deciding what type of physical communication link will be used (ARCNET, RS-232, RS-485/422, or Ethernet). Next, install M4RTU/M4IO User's Guide 41 41 OPTOCONTROL and configure communication hardware between the host PC and the M4RTU/M4IO. (Refer to the appropriate PC and M4RTU/M4IO documentation for communication hardware installation details.) Once the hardware has been installed, OptoControl must be configured to communicate over the physical communication link. Refer to the OptoControl User's Guide to configure PC communications to the M4RTU/M4IO. Configuring the M4RTU/M4IO and M4RTUX Before writing OptoControl strategies for the M4RTU/M4IO, you must inform OptoControl about the I/O installed on or connected to the M4RTU/M4IO and, if applicable, the M4RTUX. OptoControl must know how the I/O units are connected to a controller (that is, via the parallel I/O bus [local] or RS-485 serial link [remote]) as well as what type of module will be installed into each I/O channel on each unit. Once OptoControl has this information, you may use the assigned I/O tag names to reference the I/O within an OptoControl strategy. Note that the multifunction digital I/O unit (M4RTU/M4IO digital I/O) is addressed as 0 and the multifunction analog I/O unit (M4RTU/M4IO analog I/O) is addressed as 1 on the parallel I/O bus (local). Since there is no external local bus on the M4RTU/M4IO, these are the only two valid local bus addresses. These addresses are important during I/O configuration within OptoControl. Configuring M4RTU/M4IO and M4RTUX I/O Units The first step in configuring I/O is adding the I/O units. Follow the procedure listed in the OptoControl User's Guide to add an I/O unit. For the digital unit, the Type is G4 Digital Multifunction, the Port is Local, and the Address is 0. For the analog unit, the Type is G4 Analog Multifunction , the Port is Local, and the Address is 1. Remember that the digital I/O on the M4RTUX is on the same unit as the digital I/O on the M4RTU/M4IO, and the analog I/O on the M4RTUX is on the same unit as the analog I/O on the M4RTU/M4IO. Configuring Additional I/O Units Your system may have additional I/O units connected via the RS-485 serial link. Follow the procedure listed in the OptoControl User's Guide to add an I/O unit. For the configuration of these units, the Port is Remote 1, 2, or 3 depending on where the I/O is located. The Type and Address will depend on the hardware used and the jumper settings. 42 M4RTU/M4IO User's Guide CHAPTER 4: SOFTWARE AND FIRMWARE Configuring the I/O Points Follow the procedure listed the OptoControl User's Guide to add an I/O point. Notice that the Configure I/O Points dialog box shows 16 analog channels even though the M4RTU/M4IO and M4RTUX together support a maximum of only eight analog channels. This is because the M4RTU/M4IO electronics does not support the analog extender capability of an analog multifunction I/O unit. Simply ignore analog channels 8 through 15 of the Configure I/O Points dialog box. Storing User Strategies into M4RTU/M4IO Flash EEPROM User OptoControl strategies may be stored into flash memory instead of residing in RAM backed up by a battery. Flash memory has the same robust attributes of EEPROM for remote installations. Strategies may be developed for the M4RTU/M4IO in RAM, remotely downloaded and debugged, and then stored remotely in flash memory. If the M4RTU/M4IO has been set up to boot automatically from flash memory, the OptoControl strategy stored in flash will be executed upon power-up. To store an OptoControl strategy into flash memory, refer to the OptoControl User's Guide. To configure the M4RTU to run the program automatically from flash, see "EEPROM/RAM Jumper (E/R)" on page 26. OptoDisplay and OptoServer Both OptoDisplay and OptoServer share the database generated by OptoControl. This database contains the configuration information for communicating to the M4RTU/M4IO and referencing any strategy data items, such as variables, I/O, PIDs, and event/reactions. This information is used by OptoDisplay to dynamically drive a given graphic's attributes. It is also used by OptoServer to M4RTU/M4IO User's Guide 43 43 UPDATING THE M4RTU/M4IO FIRMWARE communicate to an M4RTU/M4IO or an Opto 22 Controller Network of M4RTU/M4IOs and other Opto 22 controllers. To attach OptoDisplay or OptoServer to an M4RTU/M4IO (or to an Opto 22 Controller Network containing M4RTU/M4IOs), follow the standard procedures outlined in the OptoDisplay and OptoServer online help or user's guides for adding controllers. In short, you will be telling OptoDisplay and OptoServer which OptoControl database to open to access the communication information and strategy data items. For more details regarding OptoDisplay and OptoServer, refer to the OptoDisplay User's Guide and OptoServer User's Guide. Updating the M4RTU/M4IO Firmware Use the OptoTerm utility, included on the CD with this controller, to update the firmware. For details on using OptoTerm, consult online help or the OptoControl User's Guide. IMPORTANT: If your M4RTU/M4IO controller was manufactured in June 2007 or later, it will have a Rev. 2 sticker. For Rev. 2 controllers, make sure you use OptoTerm version 4.1b or higher (included on the CD that came with the controller) to update firmware. Older versions of OptoTerm will not recognize the unit accurately. For more information, see "Notes for Rev. 2 Controllers" on page 11. 44 M4RTU/M4IO User's Guide 5: Chapter 5 Field Wiring Overview This chapter provides detailed information on digital and analog field wiring for the M4RTU/M4IO and M4RTUX. It includes examples of how to wire all currently-available G4 digital and analog I/O modules. (If a particular module is not represented, please contact Opto 22 Product Support (see page 2.) The M4RTU/M4IO and M4RTUX, shown on the following pages, use pluggable screw-style terminal blocks for field wiring. This type of terminal block gives you the advantages of both a terminal block and a connector. Terminal blocks furnish a robust individual wire attachment, while connectors enable quick multi-wire disconnection. Hence, the pluggable screw-style terminal blocks provide easy installation of field wiring and easy removal of the M4RTU/M4IO and M4RTUX, should the need arise. A bused four-position pluggable terminal block is provided on both the M4RTU/M4IO and M4RTUX. This bused terminal block is located between the two field wire terminal blocks and can be used to bus user power or commons. It is not connected to any power source or ground plane on the M4RTU/M4IO or M4RTUX. The terminal blocks for each unit reside under a cover, preventing removal without the use of a tool. When attaching field wiring, make sure that the M4RTU/M4IO is off and that field wiring is not powered, especially in hazardous environments. Field wiring should be properly prepared for terminal block installation, it should be accurately labeled, and it should be neatly dressed. Allow for adequate service loops in all field, power, and communication wiring. If you will be connecting the M4RTU/M4IO to additional I/O units via the RS-485 serial link (remote), refer to the Mistic 200 Systems Installation Guide and the Mistic 200 Family Data Book. M4RTU/M4IO User's Guide 45 45 OVERVIEW Locations of Terminals on M4RTU/M4IO Showing Logical Representation of Modules Locations of Terminals on M4RTUX Showing Logical Representation of Modules 46 M4RTU/M4IO User's Guide CHAPTER 5: FIELD WIRING Field Wiring Terminals The M4RTU/M4IO and M4RTUX field wiring terminals are located at the top of each unit, next to their corresponding digital and analog channel locations. Together, the M4RTU/M4IO and M4RTUX represent a full complement of 16 digital and 8 analog channels, equivalent to the number of channels on a standard set of one digital and one analog brick. (Although the M4RTU/M4IO electronics can support a full complement of digital and analog channels, the unit does not have enough space to support these channels; hence the need for the M4RTUX I/O Extender.) Look at the diagrams on the previous page, and note that although the I/O channels on the M4RTU/M4IO and the M4RTUX are labeled identically, these channels actually represent different modules logically. On the M4RTU/M4IO, the digital channels labeled 0-7 and the analog channels labeled 0-3 correspond correctly to digital modules 0-7 and analog modules 0-3, while on the M4RTUX, the channels with the same labels correspond logically to digital modules 8-15 and analog modules 4-7. Each digital channel has two terminals, and each analog channel has four terminals. As with the I/O channels themselves, the terminals corresponding to these channels are also labeled identically on the M4RTU/M4IO and M4RTUX, even though they represent different terminal connections. Therefore, on the M4RTU/M4IO, the terminals labeled 1-16 correspond correctly to terminal connections 1-16, while on the M4RTUX, these terminals correspond logically to terminal connections 17-32. The diagrams on the previous page show the location of the digital and analog channels, as well as their corresponding terminals for both the M4RTU/M4IO and M4RTUX. Also see Appendix D, "Worksheets," for field wiring worksheets. For additional wiring and module specification information, refer to the Mistic 200 Systems Installation Guide and the Mistic 200 Family Data Book. M4RTU/M4IO User's Guide 47 47 CONNECTING FIELD WIRING Connecting Field Wiring To connect field wiring to the M4RTU/M4IO and M4RTUX terminals, follow the diagram and procedures below. 1. Access the field wiring terminals by removing the four corner screws at the top of the M4RTU/M4IO or M4RTUX and removing the top cover. 2. Refer to the appropriate section in this chapter for the specific model of G4 digital or analog module for which wiring will be connected. Also, refer to Appendix D, "Worksheets," for a field wiring worksheet. 3. Ensure that each terminal is completely open by turning the captive screw counterclockwise until it stops. 4. Insert each wire into the appropriate terminal block location and tighten by turning the power terminal screw clockwise. Make sure the terminal block is clamping the wire and not the insulation. 48 M4RTU/M4IO User's Guide CHAPTER 5: FIELD WIRING Wiring Digital Modules Each digital I/O channel has two terminals corresponding to each installed digital module. Terminals 1 and 2 correspond to a module in channel 0, terminals 3 and 4 correspond to a module in channel 1, and so on. For polarized modules, the positive connection goes to the first terminal of the pair and the negative connection goes to the second. This wiring scheme is identical for the M4RTUX, starting with channel 8. Most Input and Output Modules Use the following diagram to wire the digital DC and AC input and output modules listed below: DC Inpurt Modules G4IDC5 G4IDC5K G4IDC5D G4IDC5B G4IDC5G G4IDC5MA AC Input Modules G4IAC5 G4IAC5A G4IAC5MA DC Output Modules AC Output Modules G4ODC5 G4ODC5A G4ODC5MA G4ODC5R G4ODC5R5 G4OAC5 G4OAC5A G4OAC5A5 G4OAC5MA G4OAC5AMA For the digital input modules listed above, the input device may be wired to either terminal. The polarity of the power does not matter except for the G4IDC5K and G4IDC5D. For the digital output modules listed above, the load may be wired to either line. For DC output modules used with inductive loads, add a commutating diode (typically a 1N4005) to the circuit as shown on the channel 6 connection to the M4RTUX. The diagram shows a DC input module wired to channel 0, an AC input module wired to channel 1, a DC output module wired to channel 6, and an AC output module wired to channel 7 on the M4RTU/M4IO. M4RTU/M4IO User's Guide 49 49 WIRING ANALOG MODULES Quadrature Input Module Use the following diagram to wire the digital quadrature input module (model G4IDC5Q). The example shows the module connected to channels 8 and 9 on the M4RTUX. Note: This module requires two digital channels. Wiring Analog Modules Analog modules use up to four terminals per analog I/O channel. The following wiring diagrams illustrate field wiring schemes for each type of analog I/O module. Voltage Input and Output Modules Use the following diagram to wire the analog voltage input or output modules listed in the table below. The diagram shows a voltage input module wired to channel 0, and a voltage output module wired to channel 3 on the M4RTU/M4IO. 50 M4RTU/M4IO User's Guide CHAPTER 5: FIELD WIRING Analog Voltage Input Modules G4AD6 G4AD6HS G4AD7 G4AD7HS G4AD9 G4AD11 G4AD12 G4AD13 G4AD22 G4AD25 Analog Voltage Output Modules G4DA4 G4DA5 G4DA6 G4DA7 Milliamp Current Input and Output Modules Use the following diagram to wire the analog milliamp current input or output modules listed in the table below. The example shows wiring to the M4RTU/M4IO on channels 0 through 3. The current loop for an input or output current device can be powered either by your own external supply or by the module. Using the module reduces wiring expense. Analog mA Input Modules G4AD3 Analog mA Output Modules G4DA3 G4DA8 M4RTU/M4IO User's Guide 51 51 WIRING ANALOG MODULES 0 to 5 Amp AC/DC Current Input or Velocity Input The 0-5A AC/DC current input module (model G4AD16) can be used to measure current directly or indirectly through a standard current transformer. Applications include measuring or monitoring current through a field device such as a motor, solenoid, or lamp. The velocity input module (model G4AD26) indicates a change in voltage by providing the first derivative of voltage with respect to time (dV/dt). Typically, potentiometer-based transducers are attached. An example of an application would be a transducer measuring piston velocity in an air/hydraulic cylinder. Use the following diagram to wire these modules. The example shows wiring of the G4AD16 to channel 0 and the G4AD26 to channel 3 on the M4RTU/M4IO. 52 M4RTU/M4IO User's Guide CHAPTER 5: FIELD WIRING Thermocouple Input or ICTD Temperature Input Module Use the following diagram to wire the analog thermocouple and ICTD temperature input modules listed in the table below. The example shows a thermocouple input module wired to channel 3 and an Opto 22 ICTD probe wired to channel 0 on the M4RTU/M4IO. When wiring thermocouples, verify that you are using the proper polarity and wire color according to the table below. Also ensure that the wire type from the thermocouple to field terminals is consistent and does not introduce other thermocouples. Note: Do not use a cold junction compensator with a G4AD24.. Polarity/Color Model T/C Type + - G4AD5 J white red G4AD8 K yellow red G4AD17 R black red G4AD18 T blue red G4AD19 E purple red G4AD23 S black red G4AD24 B gray red M4RTU/M4IO User's Guide 53 53 WIRING ANALOG MODULES 100-Ohm RTD Input Module Use the following diagram to wire an analog 100-ohm RTD input module (model G4AD10). Wire colors may vary, but make sure two wires of the same color are connected as shown. The example shows a three-wire RTD probe connected to channel 4 and a two-wire RTD connected to channel 7 on the M4RTUX. For a four-wire RTD probe, do not connect the fourth wire. Connect three wires as shown for the three-wire RTD example. For a two-wire RTD probe, add a second wire of the same type and gauge to one end, connecting it as you would a three-wire RTD. The example shows this type of connection to channel 7 on the M4RTUX. Rate Module The rate module (model G4AD20) measures the frequency of an incoming signal and produces a count based on the number of cycles per second (Hertz). For example, a count value of 1,000 indicates a frequency of 1,000 Hz. This module is ideal for directly reading the frequency of a signal or a rotating disk for RPM calculations, for example. The input amplitude range from a transducer generating a square or sine wave can be changed by adding a jumper to the hookup. Refer to the wiring example connected to channel 4. The square wave input range changes from 0.5 to 24 Vp-p to 0.25 to 24 Vp-p. The sine wave input range changes from 5 to 24 Vp-p to 2.5 to 24 Vp-p. Use the following diagram as a guide to wiring the G4AD20 analog rate module. The example shows the possible wiring options to channels 4 and 7 on the M4RTUX. 54 M4RTU/M4IO User's Guide CHAPTER 5: FIELD WIRING Time Proportional Output Module The time proportional output modules switch either 5-60 VDC (G4DA9) or 12-280 VAC (G4DA10). Together with power SSRs, they are ideal for temperature control applications, such as heating. Use the following diagram to wire either of the analog time proportional output modules. The example shows a G4DA10 wired to channel 3 and a G4DA9 wired to channel 0 on the M4RTU/M4IO.
