LM5 Modbus TCP

[OysteinEl]

For modbus master you can either use mapper by creating a JSON profile for the slave device or use scripts for the communication.
As for writing not working check the hop count value in the telegram.

{
  "manufacturer": "Test",
  "description": "Test",
  "mapping": [
    { "name": "Output 1", "bus_datatype": "bool", "type": "coil", "address": 0, "writable": 1, "write_only": 0 },
{ "name": "Output 2", "bus_datatype": "bool", "type": "register", "address": 0, "writable": 1, "write_only": 0 }

  ]
 
}
That is what i have been trying, i have a script, it works when Node-Red are the Master and LM5 act as a slave. 



I have tried using the LM5 IP address to point to itself, but it gets a connection refused. As it does not setup a Master device in it self. I can only get the LM5 to act as a slave device.
