Sample11: Module communication: method call PLC module to C++ module

This article describes the implementation:

A C++ module that provides methods for controlling a state machine.
Follow this step-by-step introduction to the implementation of a C++ module that provides an interface to the state machine.
Of a PLC module for calling the function of the C++ module.
The fact that no hard-coded link exists between the PLC and the C++ module is a great. Instead, the called C++ instance can be configured in the System Manager.
Follow this step-by-step introduction with regard to the implementation of a PLC project that calls methods from a C++ module.
