Features

MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol, and is intended to be running on the master. The only dependence is the pySerial module (also pure Python).

There are convenience functions to handle floats, strings and long integers (in different byte orders).

This software supports the ‘Modbus RTU’ and ‘Modbus ASCII’ serial communication versions of the protocol, and is intended for use on Linux, OS X and Windows platforms. It is open source, and has the Apache License, Version 2.0.

For Python 3.8 and later. Tested with Python 3.8, 3.9, 3.10, 3.11 and 3.12.

This package uses semantic versioning.
