750-333(/0xx-000), 750-833(/0xx-000)
The aforementioned fieldbus couplers allow module-specific parameterization of
behavior at diagnosis.

The aforementioned fieldbus couplers allow module-specific parameterization of
behavior at diagnosis.
For the 750-375(/025-000) and 750-377(/025-000) fieldbus couplers, the
associated user limit values can also be parameterized.

Explanation
The fieldbus coupler signals a diagnosis when
at least one channel of the I/O module reports
one of the following events:
• Measurement range overflow
• Measurement range underflow
• Short circuit
• Line break
Diagnostics reported by the I/O module do not
lead to the signaling of a diagnosis by the
fieldbus coupler.
Diagnostics reported by the I/O module lead to
the signaling of a diagnosis by the fieldbus
coupler.
Explanation
Any errors that may occur on the respective
signal channel do not cause transmission of a
diagnostic alarm nor entry in the diagnostics
database of the station proxy.
Any errors that may occur on the respective
signal channel and the error type explicitly
released entail transmission of a diagnostic
alarm. The respective error leads to an entry in
the diagnostics database of the station proxy.
An violation 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,
an
violation leads to transmission of a diagnostic
alarm and entry in the diagnostics database of
the station proxy.
