8.2.5.7 Write AS-i Slave Extended ID1 (WRITE_XID1)
With this call, the extended ID1 code of an AS-i slave with address "0" can be writ-
ten directly via the AS-i cable. The call is intended for diagnostic purposes and is
not required in the normal master mode.
The AS-i master passes the extended ID1 code on to the AS-i slave without any
plausibility check.
8.2.5.8 Set Offline Mode (SET_OFFLINE)
This call switches between online and offline mode.
The online mode is the normal operating state for the AS-i master. 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 sub-
mit 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 existing AS-i slaves are
searched and newly added AS
-i slaves are entered in the LDS or LAS.
