"Configuration mode" and "protected mode"

Recognizing the operating mode
The DP/AS-Interface Link 20E has two modes:
S Configuration mode
S Protected mode
When you press the SET button, the operating mode changes to the other mode.
Notice
Note that the SET button is only effective when the connection to the DP master is
interrupted or when the DP master is set to STOP.
Configuration mode
The configuration mode is used during AS-i installation and startup.
In the configuration mode, the DP/AS-i Link 20E can exchange data with every
AS-i slave connected to the AS-i cable (except for the AS-i slave with address '0').
Any AS-i slaves that are added later are detected immediately by the master and
activated and included in the cyclic data exchange.
When installation and startup is completed, the DP/AS-i Link 20E can be switched
to the protected mode using the SET button. Any AS-i slaves active at this point
are therefore configured. The AS-i slave information shown below is then stored in
non-volatile memory on the DP/AS-i Link 20E:
S the addresses
S the ID codes
S the I/O configuration
