#Modbus TCP Plugin for Smarthome.py

The Plugin is based on Smarthome.py for Communikate with a Wago/Beckhoff.. PLC. It Read/Writes cyclical all used Registers(Items) to the PLC. It is easy to use, like the Knx Plugin. The Plugin is based on pymodbus, which you can found under: https://github.com/bashwork/pymodbus

##install

sudo apt-get install setuptools
sudo apt-get install python-dev
sudo apt-get install libevent-dev
git clone git://github.com/bashwork/pymodbus/ -b python3
sudo python3 setup.py install

##Registerbereiche(unvollständig)

• [Beckhoff]
  • [Beckhoff BC9100 Controller] IN: 0 OUT: 16384(Merkerbereich) (lt. Beckhoff Support ist es besser nicht direkt auf den Ausgangsbereich zuzugreifen, deshalb sollte man den Umweg über die Merker nehmen)
• [Wago]
  • [Wago 750-342 Controller] IN: 0 OUT: 0
  • [Wago 750-341 Controller] IN: 0 OUT: 0
  • [Wago 750-842 Controller] IN: 0 OUT: 0
  • [Wago 750-841 Controller] IN: 0 OUT: 0
  • [Wago 758-870 Controller] IN: 0 OUT: 0
