Can read but not write to Ethernet/IP device, but no errors

Ignition

Posting this here in case anyone in the future attempts this.

We are trying to set up a proof of concept with the Ethernet/IP module v1, using it in trial mode to communicate with a Panasonic EYFR03B torque tool controller module, sans PLC.

In case anyone is curious, the manual is available to the public on Panasonic's website here. It's not my favorite documentation but it does generally cover the EIP specifications for the device.

We successfully configured the module to connect to the device and can read the input assembly as the process values change, but when we modify any data in the output assembly, the controller doesn't react at all.
Neither the controller not the EIP module are complaining or giving me any errors however.

I want to make sure that I'm not missing something on the Ignition/module end before I go ask Panasonic for support.

Any advice on how to troubleshoot outgoing Ethernet/IP connections from Ignition? I don't have direct access to the gateway machine but I can try to have IT look at something if advised.

A wireshark capture between Ignition and the Panasonic could be useful.

Also, V2 for that module is out.

Considering @pturmel created it, he may have some further input.

I'll definitely consider using Wireshark, although that might be easier said than done. Will consult with the IT department to see what resources are available.

In the end we were able to get it to work by configuring it on a PLC first, then exporting that config into the Ignition module. For all I know there was some tiny configuration mistake I missed that was properly generated by the import process.

We did change the output assembly, so maybe that was part of the issue. Who knows.
