I'm trying to communicate with a Modbus slave using RTU over TCP, but it does not work. I don't get any exception. The program seems to wait for a response and no timeout exception is thrown.
When I change the Modbus slave to TCP only, it works fine. I can read the holding registers. Does PLC4X supports Modbus RTU over TCP? If yes, is there any example? If no, are you planning to implement it?
