I am trying to read from PRO1-Mob and I have no Idea what I am doing wrong.
First question I havn't found for what is the on off switch at the RS485 Port on Neuron S103?
I have set over the EVOK the Serialport to the right 9600bps baud rate. I also found that the Neutron has an TCP Modbus Server and connected the node-red-contrib-modbus Modbus getter to the Local Server.
I set the PRO1 to ID 5 and tried to read but I get always the same error Error: Modbus exception 4: Slave device failure (device reports internal error)"
Can you tell me what I am doing wrong, I have tried to find the right solution over 3 Days but I can't find anything
