Explanation
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.
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.
Falling below the lower or above the upper user
limit on the respective signal channel does not
lead to transmission of a process alarm. The
lower and upper user limits are set in another
attribute.
Provided that the channel diagnostics of the
respective signal channel has been activated,
falling below the lower or above the upper user
limit leads to transmission of a process alarm.
No entry in the diagnostics database of the
station proxy is made. The lower and upper user
limits are set in another attribute.
Based on the value range of the input signal, a
lower limit value of the input signal can be
specified that can lead to the abovementioned
event of a process alarm.
Based on the value range of the input signal, an
upper limit value of the input signal can be
specified that can lead to the abovementioned
event of a process alarm.
