I have a modbus device and have connected a modbus RTU to ethernet converter ( and not modbus RTU to modbus TCP converter ).
All modules I have come across can read normal Modbus RTU, Modbus TCP, Modbus ASCII. But I haven't seen any module to read modbus through ethernet port.
When I tested using ModScan, I can see the data when I select Remote TELNET Server.
Is there a way I can read this data using python ??
That's a common case, the devices are remote serial/tcp converters. MOXA has tons of then.
You should understand that:
Standard modbus tcp/rtu converting devices change not only physics (ethernet/rs485 eg) but also protocol itself, removing tcp header and adding crc.
Simple serial/tcp converters (like you have) do not modify protocol.
You can use your lovely PyModbus after you manually specify rtu-framer for tcp-client.
client = ModbusClient('localhost', port=5020, framer=ModbusRtuFramer)
