CJ2M PLC with CJ1W-ETN21 card

4 posts in this topic

Hello everyone,

I would like advice on the setup below:

  • CJ2M PLC: 192.168.10.01 (Subnet: 255.255.255.0)
  • ETN21 - 192.168.20.1 (Subnet: 255.255.255.0)

PLC is collecting tag data from 192.168.10.XXX network and needs to send/receive to 192.168.20.XXX network. How should I configure the send and receive instructions?

Thank you

Well, first of all you will need a router.  They are not on the same network, so they cannot talk to each other as you have them configured without a router.

Hello Mike,

Thanks for the response. I used the Recv function to get tag information from PLCs on Network 1 (192.168.10.XXX). The ETN21 module connected to this CJ2M PLC is set to 192.168.20.XXX (Network 2 in routing table) and needs to send information over MODBUS TCP/IP. I used Omron FB MTCP_ETN_Server but it is not working. I will create a new post on this.

Hopefully, you set the appropriate Default Gateway addressing for each device.
