5.2.1 Set_Permanent_Parameter
Purpose
With this call, a parameter value for the specified AS-i slave is transferred to the
CP 243-2 . The value is saved permanently as a configured value.
The configured parameter is not transferred immediately to the AS-i slave by the
CP 243-2. The configured parameter value is only transferred when the AS-i slave
is activated after turning on the power supply on the CP 243-2.
This call is not permitted for AS-i slaves that comply with the AS-i slave standard
profile 7.4. For these AS-i slaves, the AS-i master handles the AS-i slave
parameter assignment itself. In this case, the configured parameters are always
set to F H.
