DP/AS-Interface Link 20E
Release 11/2002
C79000-G8976-C138–04
3.3.10 Set_LPS
Purpose of the Command
With this call, the list of configured AS-i slaves is transferred for permanent storage
in the EEPROM of the master.
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.
