Thanks for your reply. The Omron PLC we're using is the CJ2M with the CPU31 module. I had originally put FINS as a plan B for a couple reasons. This is just the first PLC we'll be integrating, and I want to open the door to other products in the future. Also, from what I can see there is only a Windows driver for FINS, and I'm hoping to use a Linux platform for my solution. However, schedule may dictate that we start with FINS rather than biting off a CIP implementation. I did a lot of reading through this forum (full of excellent content) and elsewhere, but I couldn't find anyone writing about OpENer use with any Omron PLCs, which led to my question. Either it's simple and nobody had a problems or it hasn't been done. :)

I'm an experienced software developer but new to interfacing to PLCs. I'm looking for a way to get data from an Omron PLC that implements CIP - I've found OpENer and that seems promising, but I see it is a Rockwell project and I'm wondering if anyone has successfully connected Omron PLCs. Without trying to join and digest the entire ODVA spec, what's the best way to get started?
