Table 7-4 Parameters Of The Event Counter - Siemens SITRANS P300 Operating Instructions Manual

You can count the limit violations for each limit monitor by activating an event counter that
provides separate, cumulative totals of upper and lower limit violations. A diagnostic warning
and / or a diagnostic interrupt can be issued once a certain number of violations is reached,
a number which you can also program. You can program the following values for the event
counter:
Table 7-4 Parameters of the event counter
Event counter: upper limit
Event counter: lower limit
Comparison value: upper limit
Comparison value: upper limit
Limit monitoring, warning/interrupt: upper limit
Limit monitoring, warning/interrupt: lower limit
Reset event counter upper limit
Reset event counter lower limit
Warning/interrupt acknowledgement

Select here whether a warning or a warning plus an interrupt should be
triggered when the comparison value is exceeded.
Select here whether a warning or a warning plus an interrupt should be
triggered when the comparison value is not met.
Specify here the number of overflows at which a warning or a warning
plus an interrupt should be triggered.
Specify here the number of underflows at which a warning or a warning
plus an interrupt should be triggered.
Select whether a warning or a warning plus an interrupt should be
triggered when the event counter upper limit is violated.
Select whether a warning or a warning plus an interrupt should be
triggered when the event counter lower limit is violated.
Here you can reset the upper limit counter to zero. A new event is not
possible until the counter has been reset.
Here you can reset the lower limit counter to zero. A new event is not
possible until the counter has been reset.
Here you can acknowledge each warning or interrupt separately.
