Explanation
The fieldbus coupler/controller signals a diagnosis, if
at least one channel of the I/O module reports the
following events:
- Measurement range overflow
- Measurement range underflow
- Overload
- Wire break
Diagnostics reported by the I/O module do not lead to
the signaling of a diagnosis by the fieldbus
coupler/controller.
Diagnostics reported by the I/O module lead to the
signaling of a diagnosis by the fieldbus
coupler/controller.
Explanation
An error on the respective signal channel does
not lead to transmission of a diagnostic alarm
nor entry in the diagnostics database of the
station proxy.
An error on the respective signal channel leads
to transmission of a diagnostic alarm. The
respective error leads to an entry in the
diagnostics database of the station proxy.
A measurement underrange on the respective
signal channel does not lead to transmission of
a diagnostic alarm nor entry in the diagnostics
database of the station proxy.
Provided that the channel diagnostics of the
respective signal channel has been activated, a
measurement underrange leads to transmission
of a diagnostic alarm and entry in the
diagnostics database of the station proxy.
