Detailed Description

Base class which implements the Modbus® server engine.

This class realises the server engine. The server engines processes Modbus messages, parses the function codes and upon receipt of a valid master query it calls Data Provider methods to exchange data with the user application. For a more detailed description which Modbus data and control functions have been implemented in the server engine see section Server Functions common to all Protocol Flavours.
