DownloadpyModSlave is a free python-based implementation of a ModBus slave application for simulation purposes. You can install the python module or use the precompiled (for Windows only) stand alone GUI (Qt based) utility (unzip and run). pyModSlave also includes a bus monitor for examining all traffic on the bus. You can also download it from pypi <https://pypi.org/project/pyModSlave/>.
pyModSlave is based on modbus-tk <http://code.google.com/p/modbus-tk/>, pySerial <https://github.com/pyserial/pyserial> and pyQt5 <http://www.riverbankcomputing.co.uk>.
Check out my modbus master project <http://sourceforge.net/projects/qmodmaster/>.
