Accumulator Point Alarm Types
For each accumulator point you can define up to four alarms for indicating when
the PV has gone beyond certain limits.
You can choose from three alarm types for an accumulator point when defining
an alarm to indicate when the PV has gone beyond certain limits:
For each alarm, you can also specify the alarm priority, sub-priority, and the
specific limit. Alarm priorities and sub-priorities are described in “Defining
Events, Alarms, and Alarm Priorities” on page 162. Alarm limits are described
below.
Alarm Limit
You use the Limit field for each alarm type to specify the value (in engineering
units) at which the alarm should be generated.
Defining Events, Alarms, and Alarm Priorities
You use the Alarms tab in Quick Builder to specify which changes in a point’s
values are recorded as events, and which point events generate alarms.
Note The priority of alarm for system events, such as communications failures, and
operator-events, Station, and printer alarms are configured using Station.
Property Description
Rate Of Change The rate of change of the PV, in engineering units per second,
exceeds the limit.
PV High The PV rises above the limit.
PV High High The PV rises above the limit which must be greater than the PV
High limit.
