AS-i 3.0 Command Interface
Commands of the Command Interface
4.6.2 Set operation mode (SET_OP_MODE: Set_Operation_Mode)
This call switches between configuration mode and protected mode. In protected
mode, only AS-i slaves entered in the LPS and whose expected and actual con-
figurations match, are being activated.
In other words: The slaves are being activated if the I/O configuration and the ID
codes of the detected AS-i slaves are identical to the configured values.
In configuration mode, all detected AS-i slaves (except for AS-i slave "0") are ac-
tivated. This also applies to AS-i slaves for which there are differences between
the expected and actual configuration.
The “OPERATION MODE” bit is stored permanently; in other words, it is retained
after a cold/warm restart.
When you change from configuration mode to protected mode, the AS-i master
will do a warm restart (change to the offline phase followed by a change to the on-
line mode).
Information!
If an AS-i Slave with address "0" is entered in the LDS, the AS-i Master cannot change
from configuration mode to protected mode.
