OVERVIEW Display Groups are a system Template display providing an overview of all tags including Block Tags assigned to the group. Overview Groups allow a large number of Tags to be displayed in a Summary Form without Graphics Building.
There is a display hierarchy that allows you to drill down: Overview -> Faceplate Group -> Block Detail -> Point Detail similar to DCS systems.
One display template can show all the Tag and Blocks in your SCADA node. Overview Groups are built automatically from Faceplate groups. You build Faceplate Groups by listing the tagnames in a list. The Over view groups use the same list.
The keymacro <F1> and the
overview icon 
on the toolbar call the Overview Display
(first page). The Overview display lists the value for Tags
and the first parameter of Block Tags, to provide an overview of
your system. The default Overview Groups are Text
Displays. They can be modified using DRAW to create Fills,
Bars and other graphical representations. The Overview Template
source is ovrgrp.dxx .
