No. 0C: Set_Operation_Mode - Siemens SIMATIC ET 200SP Manual

9.4.13

No. 0C: Set_Operation_Mode

Meaning
This command chooses between "configuration mode" and "protected operation".
In "protected operation", only the AS-i slaves that are flagged in the LPS and whose
CONFIGURED and ACTUAL configurations match are activated. This is the case when the
I/O code and the ID codes of the detected AS-i slaves are identical to the configured values.
In "configuration mode", all the detected AS-i slaves are activated - with the exception of
AS-i slave "0". This also applies to AS-i slaves that differ in their CONFIGURED and
ACTUAL configurations.
The "OPERATING MODE" bit is saved in non-volatile memory. As a result, this bit is
retained in the event of startup or restart.
On switching from "configuration mode" to "protected operation", the AS-i master restarts. It
enters the offline phase and then switches to online mode.
Note
AS-i slave with address 0 prevents switchover to "protected operation"
If an AS-i slave with address 0 is present on the AS-i bus, the AS-i master cannot switch
from "configuration mode" to "protected operation".
