Rockwell Automation FactoryTalk Metrics User Guide - Manual (Page 56)

Chapter 3 Collecting Performance Data
It is important to make sure that the total part counter and the
good/bad part counter fire at the same time (e.g., when the part
leaves the activity area). If the total part counter fires when a part
arrives, but the good/bad part counter does not fire until the part
leaves, the two part counters may be incremented in different
summarization periods, resulting in misleading part counts in
reports.
To configure the Part Count parameter:
1. Click the tab for the type of part count you want to collect:
• Total Part Count
• Good Part Count, or
• Scrap/Bad Part Count
NOTE
It is not necessary to collect all three count values;
however, at the minimum, you must collect either of the
following:
• The good part count.
• The total part count and scrap/bad count (from
which the good part count can be calculated).
For activity areas configured as manual activity areas,
you do not have to collect any part counts (i.e., Total,
Good, Scrap/Bad).
TIP
The options listed in all three tabs are identical for all
part count types.
2. Select one of the following options to indicate how
FactoryTalk Metrics should determine the number of parts of
the selected type (total, good, or scrap/bad) that the activity
area has produced:
• This Part Count Type is not in use.
