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).
SET_OFFLINE:
This call switches between the online and offline mode.
The online mode is the normal operating situation for the AS-i master. Here, the
following jobs are processed cyclically:
• During the data exchange phase, the fields of the output data are transferred to the
slave outputs for all AS-i slaves in the LAS. The addressed AS-i slaves transfer the
values of the slave inputs to the master when the transfer was free of errors.
• This is followed by the inclusion phase in which there is a search for the existing
AS-i slaves and newly added AS-i slaves are entered in the LDS or LAS.
• In the management phase, jobs from the user such as writing parameters are exe-
cuted.
In the offline mode, the AS-i/PROFIBUS Gateway only processes jobs from the user.
(Jobs that involve the immediate addressing of an AS-i slave are rejected with an er-
ror.) There is no cyclic data exchange with the AS-i slaves.
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.
If an AS-i slave with address "0" is entered in the LDS, the
AS-i/PROFIBUS Gateway cannot change from the configuration mode
to the protected mode.
