I have a simply application. TRB145 is a gateway between Modbus TCP client(Master) and RS485 RTU device(Slave). The problem is that frame received from client is send to the slave device, slave is making correct response, but the response is not send back to the TCP Client. Below is a communication diagram:
Here is the configuration of RS485:
In the attachement backup configuration of teltonika (admin password is: Zapsoft1)
and modbus log from Modbus Poll (TCP Client) and Modbus Slave (RTU).
Is there any way to log communication on RS485 (in Teltonika)?
