way the security of the application can be ensured. The reaction to a configuration er-
ror is very fast and the host can be relieved from this task. If there are any problems
on the AS-i network, the AS-interface can be switched to a secure state.
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 situations,
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.
The parameterization of Off-line Phase on Configuration Error is also supported by
the AS-i Control Tools version 3.0.
