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 NC, 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 mod-
ules including their call parameters, please refer to:

ager. Information that you need to install the PLC basic program (storage path
of file: setup.exe and additional installation instructions) are included in file:
