Collecting Performance Data Chapter 3
Event value type Description This event value type
is available for:
Collect Value at the Start and End of the
Event Collects a value when the event is activated and when it is
terminated. The initial and ending value fields are both
used by this type of event. Use this Event Value type when
you are interested in the data that will be collected when
the Event Trigger is activated and at the termination of the
Event Trigger. This Event Value type is used by the
system-generated events that monitor Part Count
information.
You may select a Value Lookup list to associate descriptive
string values with collected numeric codes.
• System-generated
events
• User-defined events
• Manual events
Accumulate Value for the Duration of the
Event Accumulates the differences between the values it collects
and stores them in the starting and ending value fields. The
starting value field will always be set to zero for this Event
Value type. The ending value will be calculated by
accumulating the differences between values received for
the duration of the event. This Event Value type is most
useful when used with the Monitored Periodic Value Event
Trigger type. This Event Value type is designed to store
counter data in situations when the user does not care
about the starting and ending values but only how much
the value has changed.
You cannot select a Value Lookup list for this Event Value
type.
• System-generated
events
• User-defined events
• Manual events
None Disables the collection of Event Value data. It is used for an
event where no additional data is associated with the
condition that caused the Event Trigger to activate. For
example, an event that is being used to track when a
certain bit value is set to On might not need to collect
additional Event Value data.
This Event Value type does not use an Event Value data
point or Event Value FactoryTalk Transaction Manager
expression, or a Value Lookup list.
• System-generated
events
• User-defined events
• Manual events
Note: Event value types available for user-defined events are also available for manual events. The difference between them is that
event values for manual events are not collected from a data point attached to the event.
For manual events a numeric value or a string value can be configured in the Specify a default Value for this Event box.
You cannot use a comma for a string value of a manual event.
