Just wondering if anyone ever had this setup. I have 3 micrologix 1400 communicating via cradlepoint modems. They in turn each is hooked to a Ethernet tunnel. I am able to hook up to any tunnel and I am able to go on line with any PLC. Can make changes if need too. Right now MSG works from 1 PLC to the main PLC. But not the other. Even thought I have communications to the PLC does that mean the MSG, if setup correctly, will work?
