DP/AS-Interface Link 20E
Release 11/2002
C79000-G8976-C138–04
3.3.18 Store_Extended_Total_Configuration
Purpose
With this call, the required total configuration of the AS interface is transferred to
the AS-i master and stored permanently in the EEPROM as the expected
configuration. This configures the DP/AS-i Link 20E.
The following data are transferred:
S The list of configured AS-i slaves specifying the AS-i slaves that can be
activated by the AS-i master in the protected mode.
S The list of configuration data specifying the ID codes and I/O configurations the
AS-i slaves must have.
S The list of AS-i slave parameters configured on the AS-i master and stored in
non-volatile memory. These parameters are transferred to the AS-i slaves when
the AS-i master starts up.
S The flags that determine the operating status of the AS-i master following start
up.
This call is not made in the protected mode.
For AS-i slaves that comply with the standard profile 7.4, the AS-i master manages
the parameter assignment itself. The parameter values for slaves complying with
standard profile 7.4 specified in the call are ignored by the AS-i master.
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.
