Python ModBus test program

A simple test program to test ModBus peripherals connected to a serial port. It is a copy/paste job based on the ModBus client which runs on the Solar Generator (https://www.meezenest.nl/mees-elektronica/solar-generator.html). Therefore, it is a bit rough around the edges. Works fine though...

It reads all known registers of the weather_station and displays its values.

Configuration

Edit config.json. Only the two values given below are needed.


  "RS485_port": "/dev/ttyACM0",
  "RS485_address": 14,

Serial settings are hard coded in the source: 9600bd 8N1

As the program is just a quick hack based on the Solar Generator software you can only run the program with the following command. All other options do not work!


  python3 ./weather_station_rs485_client.py --c config.json
