2.8.5.1 Operator Window Update Rates
The top portion of the Operator Window Parameters window contains four pairs of sliders used to deter-
mine how fast a window containing a Graphic, Group, Point, or Trend display will be updated.
The first slider in each pair determines the update rate for windows containing the specified display type
which has keyboard focus. Update rates for windows with keyboard focus range from 1 (the default) to 5
seconds.
The second slider in each pair determines the update rate for windows containing the specified display
type, but which do not have keyboard focus. The minimum update rate for these windows is 2 seconds (the
default), and the maximum is 10 seconds.
For each display type, the update rate selected for the “without focus” state must be greater than or equal
to the rate selected for the “with focus” state; that is, the number of seconds chosen on the right slider must
be greater than or equal to the number of seconds selected on the left slider. If this rule is not followed,
using the Apply or OK buttons will result in the display of a pop-up window containing the following error
message:
Focus value > no focus value
Click OK to close the error message window, then adjust the slider settings.
Changes made to the Update Rate are distributed to all other console nodes in the console group, and will
have an immediate effect on all open Operator Windows in that console group which contain Graphic,
Group, Point, or Trend displays. It is not necessary to close and re-open Operator Windows to change the
rate at which the display is updated.
2.8.5.2 Operator Window Memory Usage
Each time a new display is called up in an Operator Window, the amount of memory used by that window
will increase. When very complex displays are used often in Operator Windows, a pop-up window contain-
ing the following message may be encountered when a new display is called up:
