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.
