Collecting Performance Data Chapter 3
Select this option if you do not want to collect this type of
part count.
For manual activity areas, you can select this option for all
three tabs.
• The Plant Model Activity Area monitors a Scheduled or
Unscheduled Data Point to determine Part Count.
Select this option if you want a data point in the control
system to report the number of parts produced by the
activity area.
You can configure the way the activity determines part
counts by monitoring data points in the following ways:
• By selecting an unscheduled data point. (page 58)
• By selecting first an unscheduled data point as the part
count event trigger, and then setting the actual part
count using a FactoryTalk Transaction Manager
expression. (page 58)
• By setting the activity area to determine the value of a
FactoryTalk Transaction Manager expression on a
scheduled basis. (page 59)
• The Plant Model Activity Area evaluates a Formula to
determine Part Count.
Select this option if the number of parts produced is not
contained in a single register in the control system. For
