I am trying to get the Modbus over IP to work. My setup is that I want to access a ModBus RTU enabled device (Slave connected to TRB255) Remotely over Modbus TCP. I know that the slave is connected correctly to the TRB255, as I am able to read and write to the device over ModBus Serial Maser using the test funktion.
RS485 device configuration is enabled with the correct setting for the slave device (19200/8/1/even) and I have set up the Modbus TCP with standard port in server mode with standard port 502. I have tried different kombination of raw mode and no leading zeroes etc. but nothing seems to work. Am I missing something to complete the set up for Modbus over IP?
I am trying to acces the slave through the IP address os the TRB255.
Thanks in advance for any input.
