Micro-PWC OPERATOR’S MANUAL
Using Graphic Displays 71
7.2 Control Through Graphics
A process can be controlled from a graphic through the use of a Control pushbutton. The default label on
the button face is C, but buttons with other labels may be used. Typically, a Control pushbutton is located
near another graphical object on the graphic display, such as a valve, which is to be controlled
(
Figure 7-3 ). A graphic display can contain more than one Control pushbutton.
A Control pushbutton is configured with the name of the point (module) to be controlled. Clicking on a
Control pushbutton opens a pop-up Control window (
Figure 7-4 ) containing a single-point group model for
this point.
The appearance and use of the display in the Control window varies according to the Module Type of the
point, as described in
Section 4.3.2, Group Display . Typically, the display in the Control window allows pro-
cess values (e.g., a set point) to be changed by the use of sliders or pushbuttons. A pushbutton near the
top of the display contains the tagname of the point. Clicking this pushbutton closes the Control window
and replaces the graphic with the corresponding point display.
The title bar of the Control window identifies its parent Operator Window by number. No more than two
pop-up Control windows can be open at a time from one Operator Window. Click OK to close a Control
window. The Control window can be moved and resized in the normal fashion.
