Pymodbus also provides a lot of ready to use examples as well as a server/client simulator which can be controlled via a REST API and can be easily integrated into test suites. Pymodbus can be used without any third party dependencies (aside from pyserial) and is a very lightweight project. Supported modbus communication modes: tcp, rtu-over-tcp, udp, serial, tls
The modbus protocol documentation can be found here Pymodbus is a full Modbus protocol implementation using a synchronous or asynchronous (using asyncio) core. Version 3.2.0 is the current release (Supports Python >=3.8).Īll API changes after 3.0.0 are documented in API_changes.rst Summary Version 2.5.3 is the last 2.x release (Supports python 2.7.x - 3.7). The move from a company organization to pymodbus-dev was done to allow a 100% openness in the spirit of FOSS. We are happy to announce that we have a new home: pymodbus-dev, which is pure 100% FOSS.
