Hello,
i have a TRB255 as a modbus RTU master with 2 slaves connected.
I would like the TRB to perform automated readings on the 2 slaves and then send the data to a mqtt broker in json format. The only way i found to do so is via the “data to server” function.
The problem i have is that i also need to send commands to the 2 slaves via mqtt, so i need also the “modbus mqtt gateway” function, which can’t be activated becaus of conflicts on the serial device.
There’s a solution or a workaround? I tried with the modbus TCP over serial function but without success.
In alternative, there’s a way to have the TRB to send data to the mqtt broker in json without using automated readings and data to server?
Thank you
