3.3.6 Set_Extended_Permanent_Configuration
Purpose
This call sets the following configuration data for the addressed AS-i slave.
S
I/O configuration
S
ID code
S
Extended ID1 code
S
Extended ID2 code
The configuration data are stored permanently on the EEPROM of the
DP/AS-i Link 20E and are used as the expected configuration by the AS-i master
in the protected mode. The configuration data are specified by the manufacturer of
the AS-i slave. The meaning of the configuration data is described in /2/.
If the addressed AS-i slave does not support an extended ID code 1/2, the value
F
H
must be specified.
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).
This call is not made 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.
