9.1.2.2 PROFIBUS DP (750-333, 750-833) Fieldbus Coupler
The aforementioned fieldbus couplers allow module-specific parameterization of
behavior at diagnosis.
Table 77: General Module / Channel Parameters
Parameter
Value
Explanation
Diagnosis
Channel x (x = 0…3)
The fieldbus coupler signals a diagnosis if the
I/O module reports the events:
•
Measuring range overflow
•
Measuring range underflow
•
Short circuit
•
Line break
0 (disabled)
*)
Diagnostics reported by the I/O module do not
lead to the signaling of a diagnosis by the
fieldbus coupler.
1 (enabled)
Diagnostics reported by the I/O module lead to
the signaling of a diagnosis by the fieldbus
coupler.

9.1.2.3 PROFINET IO (750-370, 750-375, 750-377) Fieldbus Coupler
The aforementioned fieldbus couplers allow module-specific parameterization of
behavior at diagnosis.
Table 78: General Module / Channel Parameters
Parameter
Value
Explanation
Channel diagnosis
Channel x (x = 0…3)
0 (false)
*)
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.
1 (true)
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.
Diagnosis: Measuring
range underflow
Channel x (x = 0…3)
0 (false)
An undershot on the respective signal channel
does not lead to transmission of a diagnostic
alarm nor entry in the diagnostics database of
the station proxy.
1 (true)
*)
Provided that the channel diagnostics of the
respective signal channel has been activated,
an
undershoot leads to transmission of a diagnostic
alarm and entry in the diagnostics database of
the station proxy.
