A very different approach...

The Gateway would do all of the communications so there won't be any messaging at the PLC level (either end). It's primary purpose in life is a protocol bridge but because it does the messaging there is a clear advantage to using it for just that as well (even though the protocol is (almost) the same on both ends). I would imagine that communicating with 35 MicroLogix 1100's involves a significant amount of ladder logic. None of it would be needed with the Gateway. The Gateway also has a Heartbeat tag that each MicroLogix could use to determine if it is communicating with the Gateway so if comms are lost it would know to close the gate. The app engineers at Spectrum can go over details about your application if you're interested.
