8.2.1.7 Set_Operation_Mode
Meaning
This call changes the module between the “configuration mode” and the “protected
mode”.
In the protected mode, only AS-i slaves are activated that are entered in the LPS
and whose expected and actual configurations match, in other words, when the I/O
configuration and ID codes of the detected AS-i slaves are identical to the
configured values.
In the configuration mode, all detected AS-i slaves (except for AS-i slave ”0”) are
activated. AS-i slaves in which there are differences between the expected and
actual configuration are also activated.
The “OPERATION MODE” bit is stored permanently; in other words, it is retained
following a cold/warm restart.
The following bit assignment applies to the operating mode:
S Protected mode: “0”
S Configuration mode: “1”
When you change from the configuration mode to the protected mode, there is a
warm restart on the AS-i master (change to the offline phase followed by a change
to the online mode).
Notice
If an AS-i slave with address 0 is entered in the LDS, the IE/AS-i LINK cannot
change from the configuration mode to the protected mode.
