There are two different ways to parameterize the AS-i master for this feature:
• Every configuration error during normal operation in protected mode releases
the off-line phase.
• For each slave address can be chosen whether a configuration error on this ad-
dress will release the off-line phase or not. This information is stored in the List
of Off-line Slaves (
LOS ).
The user himself can decide how the system reacts to a configuration error on
the AS-Interface. The AS-i master can release the off-line phase in critical situ-
ations, i. e. only with certain slave addresses, while in less critical situations (if
one of the other AS-i slaves have a configuration error) only the error message
configuration error is sent to the host, but AS-i is still running.
