Modbus question

Got a PM from a user "shwe", thought it should be a thread instead:

I guess I was one off, whichever. I think DNS showed up in the 1200 somewhere along the way as well. New FW def does add OPC UA to the 1200, which is nice.

The 200 -> 1200 converter isn't great, because there are some concepts in the 200 that don't map over exactly, but it's better than nothing. 1200s convert to 1500s almost 100% with minimal effort.
