So interesting request and I didn't see any posts that jumped out to me about connection TO ignition via Modbus... We have a request to have our BMS (Carrier I-vu) system connection to one of our ignition projects in order to pull readings from a process cooling water flow meter. Anyone point me in a direction for some documentation or help? I'm not an ignition developer and wouldn't do this myself, but tasked with finding the feasibility.
You might take a look at @pturmel Modbus driver. I think it can act as a Modbus client server. He would be a good resource to ask though.
Edit - My Modbus experience showing through

This would be Modbus server mode, and yes, my driver does this. (Server mode was the original motivation, but it also has a client mode that fills in some features missing from the IA driver.)
Read through to the end of that topic for latest downloads, or go to my own Module Sales page.
