I successfully got a Micro 820 (Slave) and Red Lion HMI (Master) to work together using Modbus TCP. But now I need to add an Automation Direct Solo Temperature Controller to the PLC, which uses Modbus RTU. I don't mind the learning curve, but part of me wonders if the Micro can be a Master on the RTU, and a slave on the TCP at the same time. Anybody able to offer some experience on this?
