Chapter 9 Measure and Improve Runtime Application Performance

Reviewing Background

Updates

Tags are continuously updated by the runtime application whether or

not the operator is on a specific display. Tags update according to the

maximum tag update rate for the associated feature.

The more familiar you are with these tags and features, the easier it is

to update and fine tune your application.

Global Connections

The Global Connections editor provides a list of connections that you

can assign to tags.

• Date and Time

• Display

• Macro

• Backlight

• Memory

These tags are continuously updated in the background by the

application, regardless of what display is currently active. The tags

update according to the setting of the maximum update rate

parameter.

TIP

Set noncritical tags to a longer maximum update rate. Set

critical tags to a lower rate so that time-sensitive information is

always available to the operator.
