I can not send modbus RTU  data to my MQTT server.
I have set up "modbus serial master" to collect data from PLC connected to RS485 on TRB255. This part is working fine, I tested it using test button provided by TRB255 UI.
Using "data to server" I am trying to send collected data to MQTT broker. It does not work as expected. I can see TRB255 is connected to the broker, but does not publish any data collected from RS485.What am I doing wrong?
