Table 4-1 Use and content of the master copies of the PLC basic program
Folder Purpose Contents
840D sl PLC Ba‐
sic Program
This master copy is intended
to create a completely new
project.
The master copy contains all the blocks that you require for the maximum
configuration (31 axes, 10 channels).
Use of axis/channel DB
If your machine is using fewer axes or channels, you can either copy only
the required blocks or you can delete the blocks that are not required in the
project tree after copying.
If you have blocks in your project that are not required, this increases,
for example, the time required for the loading or export of the PLC symbols.
Use of ALMSG_DB [DB2]
This master copy contains ALMSG_DB [DB2] in the variant Exten‐
dAlMsg=False.
The used DB2 variant must match in the startup for parameterization of the
RUN_UP [FB1] in OB100 [OB100] (parameter ExtendAlMsg).

sic Program
(upgrade)
This master copy is used to
upgrade blocks after the firm‐
ware version of an NCU is up‐
dated, i.e. if you have carried
out a device replacement
(Page 33) or a migration.
This master copy contains all the know-how-protected blocks that you re‐
quire for the maximum configuration (31 axes, 10 channels).
Blocks to be changed by the user are not included (no organization blocks
and not FC12 [FC12], Diagnose [FB29], DB4 [DB4], DB5 [DB5]).
Use of axis/channel DB
If your machine is using fewer axes or channels, you can either copy only
the required blocks or you can delete the blocks that are not required in the
project tree after copying.
