WAGO-I/O-SYSTEM 750
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 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.
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.
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.
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.
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.
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.
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.
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.
