Chapter 3 Collecting Performance Data
example, you can create user-defined events to trap and record
downtime occurrences, e-stops, the upstream/ downstream status,
machine state information, and operator input.
The ability to direct FactoryTalk Metrics to monitor custom events
in the control system is extremely powerful, because it allows you to
customize FactoryTalk Metrics for your unique situation and
objectives.
It is up to you what is captured and how it is interpreted. There is no
enforced limit to the number of custom events that can be associated
with a plant model activity area in FactoryTalk Metrics. However,
the addition of each new event consumes more resources from all the
system's components.
The performance parameters for a user-defined event include:
• Identifying information
The plant model activity area (referred to as “workcell
description” in the FactoryTalk Metrics event history report
data source), event category (a user-defined grouping or folder
of related events), and event description (user-defined).
For more information, see "FactoryTalk Metrics Event
History Report Data Source" in the Configuration Console
online help.
• Summarization rules
Define how FactoryTalk Metrics will handle the creation of
multiple summary records in the database for a single event
occurrence.
For more information, see "Set the Event Data Summarization
Parameters" in the Configuration Console online help.
