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 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:

6.1.4 Installing the PLC basic program library
To be able to use the blocks of the basic PLC program (OBs, FBs, DBs, etc.) in
a SIMATIC S7 project, the library must first be installed in the SIMATIC man-
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:
S <Installation path>\importantinfo.rtf
Notice
The library of the basic PLC program must be installed on the computer on
which the SIMATIC manager for creating the S7 project is already installed.
