Chapter 3 Collecting Performance Data

You can set the collection rate in the range of 1 to 60 seconds. This

setting does not affect unscheduled part counters, which are

collected as often as they change.

When configuring the setting, take into account the following:

• The lower the number, the more often the data will be

collected from the control system. Using a lower number

enables a greater resolution in data collected from rapid

processes. The part counts will be stored in a record that spans

10 minutes (by default), so a higher resolution in collecting the

part count data does not translate into a higher resolution for

reporting.

• The greater the number, the less often the data will be

collected. Using a higher number can help with server loading

in slower processes. The downside is that collecting part

counts infrequently can lead to count inaccuracies when, for

example, part count registers are reset.

Under System Generated Event Data Summarization, select the

data summarization type that will be used by system-generated

events. The summarization behavior of custom events is defined for

each event.

The following data summarization types are available:

• Scheduled Shift Start

• Scheduled Shift Start and End

System-generated Event
