3.3.8 Store_Actual_Configuration
Purpose of the Command
With this call, the (actual) configuration data (I/O configuration, ID code, extended
ID1 code and extended ID2 code) of all AS-i slaves are stored permanently in the
EEPROM as the (expected) configuration data. The list of activated AS-i slaves
(LAS) is adopted in the list of permanent AS-i slaves (LPS).
When this command is executed, the AS-i master changes to the offline phase and
then changes back to the normal mode (warm restart on the AS-i master).
The call is not executed in the protected mode.
Note
If you use CPUs from the SIMATIC S7 system as the PROFIBUS DP master, then
dependent on the configuration in STEP 7, these may send a complete AS-i slave
configuration to the DP/AS-i Link 20E during the DP startup. Use of the call
described here is then generally unnecessary.
