Hi, i'm trying to link an OMRON CJ2M PLC to the PC (server) but not sure which of these drivers are to be use. PC is connected to Omron PLC hardware via USB connection, and working fine with CX-Programmer. Help is appreciated !

1) Omron FINS Driver Tags
2) Omron HOST Link Driver Tags

If your model has ethernet, I understand that it uses CIP.

The CJ's use the FINS driver.

The Hostlink driver is the old serial interface.

Sorry, the CIP driver was written specifically for the Rockwell COmpactlogix and Controllogix versions of CIP. It doesn't actually work for any other brands.
