This is the file I have used for my video about creating a Modbus TCP server in Python. Here is the link to my video.
The file Simple_ModbusServer.py contains the code for a simple Modbus Server with the following register description:
| Holding Register Addr. | Description |
|---|---|
| 0 | Server writes a random value to it every 500 ms |
| 1 | Server monitors this register for changes. If the value is changed by the client, the server will print out the new value |
To run the script, you need to have pyModbusTCP installed on your machine. To install it, you can use:
sudo pip install pyModbusTCP
