For loading the configuration into the PLC, the following prerequisites must be
fulfilled:
S
A communications link exists between STEP 7 and the PLC.
S
The configuration to be loaded corresponds to the actual station configura-
tion.
S
SINUMERIK 840Di sl is active:
– NC: Cyclic operation
– PLC: RUN or STOP mode
Note
You are recommended to check consistency of the configuration before
loading it.
HW Config: Station > Check consistency
The following supplementary conditions regarding the system data blocks are
observed when the configuration is loaded:
– SIMATIC Manager
When loading the configuration via the SIMATIC manager all the system
data blocks are loaded into the module.
– HW Config
When loading the configuration via HW Config, only the system data
blocks generated by HW Config during compilation of the configuration
are loaded into the module.
System data block SDB210 of the MPI configuration is therefore not ad-
ditionally loaded.
As part of the MPI configuration, system data block SDB210 has also been
loaded into the block directory of the PLC. Because of the supplementary condi-
tions stated above, system data block SDB210 is only loaded into the PLC if it is
loaded with the SIMATIC Manager.
When the configuration is loaded into the PLC for the first time, it must be
loaded from the SIMATIC Manager.
Notice
When loading the configuration into the PLC, the system data block of MPI
configuration SDB210 is only loaded with the SIMATIC Manager, not with HW
Config.
