Set operating mode (SET_OP_MODE, 0x0C)
SET_OP_MODE: Set_Operation_Mode
This call can be used to select between set-up mode and protected mode.
The AS-Interface master should only be operated in set-up mode during
commissioning (when setting up). By default, it is operated in protected mode.
In protected mode, only those AS-Interface slaves are activated, which have
been marked in the LPS and the required and actual configurations of which
correspond, i.e. when the I/O configuration and the ID code of the detected
AS-Interface slave are identical with the set-up values.
All detected AS-Interface slaves (apart from AS-Interface slave "0") are
activated in set-up mode. This also applies to AS-Interface slaves where there
are differences in the required and actual configurations.
The "OPERATING MODE" bit is stored in non-volatile memory, i.e. it is
retained even on start-up/restarting.
When changing from set-up mode to protected mode, the AS-Interface master
restarts (transition to offline phase and subsequent switching to online mode).
Note
If an AS-Interface slave with the operating address 0 is entered in the
LDS, it is not possible for the AS-Interface master module to switch from
set-up mode to protected mode.
