We have a few remote sites with multiple CompactLogix PLCs in them that we are finally converting from low-speed radios to cell modems. We are using Sierra Wireless GX450 modems which have routing capability in them, but we can not seem to figure out how to use a MSG instruction to include a port number.
Has anybody had success in talking to two different PLCs with a single modem? Or being able to specify a port number in RSLogix?
