I'm looking for a Modbus TCP to RTU device server that has a status register in it that can be read from the TCP side. This status register needs to indicate the communication status to all the devices on the RTU side.
Our PLC only talks Modbus TCP but we have six safety valves that only talk Modbus RTU. The safety valves don't have any sort of heartbeat signal and therefore we are relying on the protocol converter (device server) to tell us that one or more devices on the RTU side have stopped communicating.
Any recommendations?
