Hello,
I am trying to connect a pair of UNIPI NEURON S103 using MODBUS TCP communication in NODE-RED. So far I have not succeeded.

1. is it necessary to set MODBUS TCP communication in UNIPI?
2. is there a guide on how to perform MODBUS TCP communication in Node-Red?
3. can an example for Node-Red Modbus TCP communication be downloaded somewhere?
   Thank you
