• In the management phase, jobs by the user such as writing parameters are ex-
ecuted.
In the offline mode, the AS-i/PROFIBUS gateway processes jobs by the user only.
(Jobs that involve the immediate addressing of an AS-i slave are rejected with an
error). There is no cyclic data exchange with the AS-i slaves.
When offline, the AS-i circuit is in a safe state.
The OFFLINE = TRUE bit is not permanently stored; in other words, following a
cold/warm restart, the AS-i/PROFIBUS gateway is once again in the online mode.
