Loading the configuration
Note
You are recommended to check consistency of the configuration before loading
it.
Supplementary
condition
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 additionally loaded.
First loading
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 conditions 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.
