PyModbus is a full Modbus protocol stack written in Python, providing a client, server, and HTML-based simulator with both synchronous and asynchronous APIs. It targets communication with industrial devices like PLCs and sensors over TCP, RTU, and serial transports.
Use cases
- read registers from a modbus PLC over TCP
- simulate a modbus slave device for testing
- poll sensors with modbus RTU over serial
- build a modbus master client in python
- write a modbus server to emulate industrial equipment
- integrate SCADA systems with python
When to choose
- you need a mature, full-featured Modbus implementation in Python
- you want both client and server plus a simulator
- you need sync and asyncio APIs
- you communicate with standard-compliant Modbus devices
When to avoid
- your devices rely heavily on non-standard Modbus extensions
- you need extremely low-latency or hard real-time communication
- you are not working with the Modbus protocol at all
