Issues connecting to Omron CJ1W-ETN21 Expansion Module

General Discussion

Hi all,

I am trying to connect an Omron PLC to ignition through the CJ1W-ETN21 expansion module using Omron FINS/TCP protocol but cannot establish communication.

I have had no issues connecting to Omron PLCs with the ethernet port directly on the CPU but can't seem to figure it out for the expansion module.

I have set the IP address, subnet mask, gateway address, conversion type to combined, and I adjusted the switches on the module to match the last octet of the IP address.

Through ignition, I tried to make the connection as I did for the other Omron PLCs. I created the device connection, selected Omron FINS/TCP driver, input a name and the hostname, and left the other settings as they were defaulted.

Is there a step that I am missing? What needs to be done differently to be able to connect through the expansion module?

Thanks!

I didn't have to do anything special.

Hi Jordan, Thank you for the response.

This is how we set it up.

What should we change?

Update:

Was able to get connected to one by adding the IP address table.

We have two more that we are trying to connect. Have configured them the same way with the only difference being the unique IP addresses, and they will not connect.
