General

Brief description
This chapter describes the functionality of various interface signals which are of general
relevance, but are not described in the function-specific chapters.
Interfaces
The exchange of signals and data between the PLC user program and the NCK (kernel of
the numerical control) or HMI (display unit) is performed via various data areas. The PLC
user program does not have to handle the exchange of data and signals. From the users
point of view, this takes place automatically.
