8 Using the Data Record Interface
8.2.2
AS-i Slave Calls
8.2.2.1
Set_Permanent_Parameter
Meaning
With this call, a parameter value for the specified AS-i slave is configured on the
IE/AS-i LINK. The value is stored permanently in the storage of the IE/AS-i LINK or
on the C-PLUG, if this is inserted.
The configured parameter is not transferred immediately by the IE/AS-i LINK to
the AS-i slave. The configured parameter value is only transferred when the AS-i
slave is activated after turning on the power supply on the IE/AS-i LINK.
After the job, the AS-i master changes to the offline mode and then changes to the
normal mode (warm restart on the AS-i master).
For some AS-i slave profiles (combined transaction type), the AS-i master
manages the AS-i slave parameter assignment itself. In this case, the parameters
in the call are ignored.
Note
If you use CPUs from the SIMATIC S7 system as the PROFINET IO controller,
then dependent on the configuration in STEP 7, these may send a complete AS-i
slave configuration to the IE/AS-i LINK during startup. Use of the call described
here is then generally unnecessary.
