I am currently converting a citect project to ignition and I am trying to connect to an OMRON CJ1M-CPU11 PLC via the ignition Modbus TCP driver. The PLC has an Ethernet CJ1W-ETN21 module. Through ignition I can connect to the PLC but when I try to address tags (according to the Modbus Ethernet addressing in the ignition user manual) I get errors stating that they are not connected. I am a bit of a newbie when it comes to OMRON PLC’s and Modbus and would appreciate a little advice for the address of the tags in ignition. I have attached a list of the tags I pulled from Citect which are the same addresses in the PLC.
Any help is appreciated.
