You can write to holding registers, using Modbus functions Write Single Register or Write Multiple Registers (ModbusTcpClient. Quick Start Connect to a Modbus device with PyModbus in under 5 minutes. The “pymodbus” library provides a wide range of features and supports various Modbus variants, while “minimalmodbus” is a lighter and simpler Install PyModbus with pip or conda on Windows, Linux, and macOS. It covers both synchronous and asynchronous client implementations across various communication protocols Pymodbus is a full Modbus protocol implementation offering a client, server and simulator with synchronous/asynchronous API. I am using pymodbus, and I wrote the code segment below. Server Pymodbus offers servers with transport protocols for Serial (RS-485) typically using a dongle TCP TLS UDP possibility to add a custom transport protocol communication in 2 versions: The example uses “comm”: “tcp”, so the entries are arguments to pymodbus. Simple The author suggests that Python, with its supporting libraries, is a suitable tool for implementing Modbus communication due to its simplicity and flexibility.
