pyNETVARS
Python module for network variables for CoDeSys PLCs
CoDeSys v2.3 supports so called network variables. Blocks of (global) variables, that propagates over networks like TCP, UDP or UDP Multicast aso.
This python module supports parsing, receiving and sending those blocks (with UDP Multicast only).
With this you can add for example a Raspberry Pi Sensor to your automation network without special Network clients on your PLC.
