SINUMERIK 840Di Manual (HBI) – 06.03 Edition
7.3.9 Loading a configuration into the PLC
For loading the configuration into the PLC, the following prerequisites must be
fulfilled:
S
“HW Config” is active
S
Current system data blocks are available
S
An MPI connection is established between “HW Config” and the PLC
S
SINUMERIK 840Di is active, i.e. the NC is in cyclic operation and the PLC in
either of the states RUN or STOP.
The system data blocks (SDB) are generated by compiling the current configu-
ration using “HW Config”. They contain the relevant information required for
communication of the module with the entire system.
Before saving and compiling the current configuration, it is recommended to
check the consistency of the configuration using the menu command Station >
Check Consistency.
If “HW Config” finds any inconsistencies within the configuration, an error dialog
box appears, which displays the appropriate error messages and possible rem-
edies.
The menu command Station > Save and Compile saves the current configura-
tion in S7 as an object: Station and is then compiled. The compilation includes
a consistency check of the parameterized settings.
If no inconsistencies are contained within the current configuration, the system
data blocks are generated and stored in the folder Blocks of the corresponding
module.
The system data blocks for the created configuration are to be found at:
