CJ-series Ethernet Unit CJ1W-ETN21 CSM_CJ1W-ETN21_DS_E_6_5 Organically Connect the Production Site and Management * Select the required communications services according to application needs to flexibly integrate PLCs with an Ethernet information network. CJ1W-ETN21 Features * Use Ethernet to implement various communications protocols. * Implement FINS message communications using UDP/IP or TCP/IP with a user application on a host computer or with Support Software, such as the CX-Programmer. * Use the clock on an SNTP server to automatically adjust the clocks in the PLCs connected to the Ethernet network. (An SNTP server is required separately.) * An FTP server is built in, so files can be used to transfer PLC data between network PLCs and workstations or personal computers with an FTP client. * Email can be used to send commands to the PLCs, or triggers can be set so that the PLCs will send PLC data or Ethernet Unit status to a host computer. * The standard UDP/IP and TCP/IP protocols are supported to enable communications with a wide range of devices, workstations, personal computers, and Ethernet modules from other manufacturers. * The SMTP/POP3/SNTP servers enable the use of host names instead of IP addresses. (A DNS server is required separately.) System Configuration CX-Programmer CX-Integrator SYSMAC Gateway FinsGateway Hub Twisted-pair cable 100 m max.

Function prohibiting access using FINS/ UDP from nodes with dynamically changed IP addresses Access to change the remote IP address from a node using FINS/UDP can be prohibited (IP address protection). Unit Version 1.4 Upgrade ETN11-compatible mode added to the ETN21 settings for FINS/UDP. Details A mode compatible with the CS1W-ETN11/CJ1W-ETN11 was added in the operating specifications for FINS/UDP messages sent from a different UDP port number than the FINS/UDP port number set in the Ethernet Unit. Unit Version 1.5 Upgrade Details CIDR function added to subnet mask settings An option setting was added to the subnet mask settings to enable CIDR. Enabling CIDR allows you to use classless IP addresses in the subnet mask setting. High-speed option added for socket service This option can be set to improve communications performance for the socket service that is implemented by manipulating dedicated control bits. The performance is the same as the previous version if this option is not set. Linger option added to socket options for TCP open requests. A linger option can now be set in the options for passive or active TCP open requests. Location of node address switches changed on CJ1W-ETN21 The location of the node address switches was changed. The setting method and setting range remain the same. Note: CX-Programmer version 8.2 or higher is required for unit version 1.5 functions.
