Omron CJ1W-ETN21

The Omron CJ1W-ETN21 Ethernet Unit is designed to seamlessly integrate CJ-series PLCs with Ethernet networks, offering flexible communication options tailored to your application needs. This unit supports both 100Base-TX and 10Base-T Ethernet standards, ensuring reliable and high-speed data transfer.

With the CJ1W-ETN21, you can implement various communication protocols using Ethernet, including FINS message communications via UDP/IP or TCP/IP. This enables seamless interaction with host computers and support software like CX-Programmer. The built-in FTP server facilitates efficient file transfers between networked PLCs and workstations or personal computers equipped with an FTP client.

Additionally, the unit supports email functionality, allowing commands to be sent to PLCs or triggers to be set for sending PLC data or Ethernet Unit status to a host computer. The standard UDP/IP and TCP/IP protocols ensure compatibility with a wide range of devices, workstations, and Ethernet modules from other manufacturers.

The CJ1W-ETN21 also features automatic clock adjustment using an SNTP server, ensuring synchronized time across all connected PLCs. The SMTP/POP3/SNTP servers allow the use of host names instead of IP addresses, enhancing network management and configuration flexibility.

Designed to meet international standards such as UL, CSA, cULus, NK, Lloyd, and CE, the CJ1W-ETN21 Ethernet Unit is a reliable and versatile solution for industrial automation applications.
