Ds 131 Read Status Of Option Handling - Siemens SIMATIC ET 200SP Manual

Note
Identical entries in each list
If a "1" is entered for an AS-i slave in both lists, the slave will be deactivated.
Note
Activated/deactivated status of the optional slaves
The activated/deactivated status of the optional slaves is stored in non-volatile memory of
the master and is retained even if a new configuration is downloaded to the master. The
status of an optional slave is set to deactivated if the slave is not set as optional in a
configuration.
If a configuration contains slaves without option handling, the status stored internally in the
master for these slaves is reset (bit = 0).
