Upgrading the PLC basic program

If you upgraded the firmware of an NCU or carried out a project migration, you should then also
upgrade the PLC basic program to the current version.
However, it is essential that you check beforehand whether you would inadvertently overwrite
your own blocks (see requirement).
Requirement
● Block number ranges of the SINUMERIK PLC basic program in the project are not occupied
by blocks of other creators or you have checked which blocks of other creators are located
in the SINUMERIK number range (Page 66).
Procedure
To upgrade the PLC basic program, proceed as follows:
1. Switch to the "Libraries" task card and open the PLC basic program that matches the
firmware version of the inserted NCU:
– SINUMERIK 840D sl PLC basic program V4.5.x.x
– SINUMERIK 840D sl PLC basic program V4.7.x.x
– SINUMERIK 840D sl PLC basic program V4.8.x.x
