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.
