modbus-tk: Create Modbus app easily with Python ================================================= [](https://semaphoreci.com/ljean/modbus-tk) Download / Install ------------------------------------ Current version is 1.1.2 It is available on PyPI https://pypi.python.org/pypi/modbus_tk License ------------------------------------ This is distributed under GNU LGPL license Description ------------------------------------ Make possible to write modbus TCP and RTU master and slave. It can be used for testing purpose : It is shipped with slave simulator and a master with a web-based hmi (ok the hmi need to be improved :). It can also be used to create any application which need to communicate over modbus. It is a full-stack implementation and is used on "real applications". Thanks to Python and the incredible set of existing libraries, it can fit a lot of different needs : database logging, HMI, report generation ... modbus-tk is different from pymodbus which is another implementation of the modbus stack in python. modbus-tk tries to limit dependencies (even if it requires pyserial for Modbus RTU). modbus-tk has no link with tkInter. tk stands for 'testkit' or 'toolkit' depending of the way you use it. Discussion group ------------------------------------ Please join the modbus-tk discussion group to participate : https://groups.google.com/forum/?hl=fr#!forum/modbus-tk Features ------------------------------------ * Modbus TCP support for writing masters and slaves * Modbus RTU support for writing masters and slaves (requires pyserial) * Modbus RTU over TCP support * Can be customized with hook mechanism (simulate errors, timeouts...) * ready-to use simulator with RPC interface * Defines very easily your own memory blocks * Set/Get values for any place in a memory block * logging capability through python logging module * Web-based HMI (experimental feature which requires bottle) Feedback ------------------------------------ Feedback is welcomed!
