Programming the PLC
4.6 Upgrading the PLC basic program
3. Depending on the block number assignment in your project, select one of the following
options:
The blocks are copied to your project. A check is made for duplicate block names and
the "Conflicts during copying" dialog (Page 74) is displayed.
Note
Copy further required blocks separately (e.g. DB2 variant "ExtendAlMsg=True")
If you are using PLC basic program blocks that are not contained in the master copies folder
"840D sl Basic Program > 840D sl PLC BP", you must copy them separately:
● DB2 variant "ExtendAlMsg=True" from the master copies folder
● Different external STL sources from the master copies folder "External source files"
See: Using copy templates (Page 58)Create blocks from external sources (Page 84)
4. Select the option "Replace existing objects and move to this location" and confirm with "OK".
5. In the project tree, right-click "Program blocks" and select the "Software (compile all blocks)"
command in the "Compile" shortcut menu.
Result
The PLC basic program has been upgraded and is currently compiled.
Now you can check the copied blocks and, if applicable, manually delete the PLC basic
program blocks that you do not require (e.g. unused axis DB, channel DB, FB or FC).
If you have unused blocks in your project, some tasks take unnecessarily long, e.g. the loading
or the creation and import of SINUMERIK archives.

Possible procedure
Overwriting specific PLC basic program blocks
1. Open the lower-level master copies folders and select only those
PLC basic program blocks that you use in your project.
– To select successive objects, click on the first object, press and
hold the Shift key and then click on the last object.
– To select non-successive objects, press and hold the Ctrl key
and click on the objects one-by-one.
2. Drag and drop the selected blocks into your "Program blocks"
folder, e.g. under "CNC_1 > PLC_1 > Program blocks".
Overwriting the PLC basic program including folder structure as a whole
Drag and drop the entire master copies folder "840D sl PLC BP" into
your "Program blocks" folder, e.g. under "CNC_1 > PLC_1 > Program
blocks".
