6.1.3 PLC program
The PLC program is constructed modularly. It comprises the two parts:
● PLC basic program
The PLC basic program organizes the exchange of signals and data between the PLC
user program and the NCK, HMI, and machine control panel components.
The PLC basic program is part of the PLC Toolbox supplied with SINUMERIK 840Di sl.
● PLC user program
The PLC user program is the user-specific part of the PLC program by which the basic
PLC program has been added to or extended.
For a complete description of the basic PLC program, its structure and all modules including
their call parameters, please refer to:
