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 75: General Module / Channel Parameters
Parameter
Value
Explanation
Channel diagnosis
Channel x (x = 0…7)
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…7)
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.
Diagnosis: Short
circuit
Channel x (x = 0…7)
0 (false)
A short circuit on the respective signal channel
does not lead to transmission of a diagnostic
alarm nor to entry in the diagnostics database of
the station proxy.
1 (true)
*)
Provided that the channel diagnostics of the
respective signal channel has been activated, a
short circuit leads to transmission of a
diagnostic alarm and entry in the diagnostics
database of the station proxy.
Diagnosis: Measuring
range overflow
Channel x (x = 0…7)
0 (false)
An overrange 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
overrange leads to transmission of a diagnostic
alarm and entry in the diagnostics database of
the station proxy.
Diagnosis: Wire break
Channel x (x = 0…7)
0 (false)
A wire break on the respective signal channel
does not lead to transmission of a diagnostic
alarm nor to entry in the diagnostics database of
the station proxy.
1 (true)
*)
Provided that the channel diagnostics of the
respective signal channel has been activated, a
wire break leads to transmission of a diagnostic
alarm and entry in the diagnostics database of
the station proxy.
