Creating a PLC reload archive

You can save the program blocks of the PLC as reload archive in the TIA Portal.
Note
F-blocks are not saved in reload archives
The F-blocks used in the SINUMERIK Safety Integrated plus (F-PLC) mode are not saved in
reload archives.
If you want to save F-blocks in a SINUMERIK archive, you can save them together with the
associated hardware configuration in a PLC commissioning archive.
Note
In the PLC reload archive, existing data blocks overwrite any CPU DBs during reading in
If you import into a PLC reload archive a CPU DBs that already exists on the control system,
the CPU DBs on the control system will always be overwritten. Therefore the option
"Overwrite existing blocks with identical number on the PLC for import" does not affect CPU-
DB.
Therefore, do not store data blocks that already exist on the NCU as CPU DB in the PLC
reload archive.
If you have already overwritten CPU DBs, you can find further information in the information
system, keyword "Inconsistency in data blocks".
Requirement
● If possible, the "Program blocks" folder should not contain any program blocks of not
activated axes/spindles or the tool management.
Although you can save unused program blocks in the archive, this extends the time
required for creating and loading the archive.
● The data carrier to be used or storage location is available and has sufficient storage
space.
Procedure
To create a reload archive, proceed as follows:
1. You have several ways of selecting the program blocks to be archived:
– Select the desired program blocks in the project tree or in the project tree overview.
– Right-click the program blocks folder of the PLC or a higher-level folder.

Then right-click one of the selected program blocks.
You can change the actual program blocks to be exported later in the "Create
SINUMERIK archive" dialog.
You can select the program blocks to be exported later in the "Create SINUMERIK
archive" dialog.
