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.)
