ModbusTCP, NI vs Wago PLC

​ This module provides a simple Modbus TCP slave.

All communication therefor is initiated from the PLC.
The following function codes are supported :
FC1, FC2 , FC3 , FC4 , FC5 , FC6 , FC15 and FC16.
However, the entire memory is readable and writable.
Bit and register commands access to the same memory area.
If higher speed is required, the shared memory can be accessed directly.
Examples for addressing can be found in the program code. The Modbus
address 0 corresponds thereby the index 1 in the shared memory.

It's in beta state an still under development.
