0 = activate protected mode
1 = activate configuration mode
When changing to the protected mode the master normally passes the "offline phase" where all
connected slaves (and so all outputs) are reset for some seconds.
If the master flag "no offline phase" is set, the "offline phase" and the reset are not executed.
The status of this flag can be changed by the command 1C
h
(
) or via the menu items
[Master Setup] > [AS-i Master x] > [Slave Reset] of the controllere.
