Optimize Runtime Performance Chapter 9
Reviewing Background
Updates
Background 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 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.
