I have a Modicon Compact 984-A141 Modbus comm port connected to a Modicon Micro's comm port. There are no I/O on this Micro. The I/O Exp. Link port on this Micro is connected 100 feet away to the I/O Exp. Link port on another Micro. The distant Micro has I/O connected. I have an undocumented (uploaded) copy of the Compact program in ProWorx. I can't see how the Compact is communicating with the Micro. I need to find out how the Compact is using the I/O to/from the distant Micro, but I don't see anything in the Compact configuration. There are no XMITS in the Compact program. Don't have much Modicon experience, so I might just be missing something simple. Any suggestions appreciated!! Compact program attached. Thanks (and Merry Christmas)!!
