3.4 DISPLAY MODES (Cont.)
3.4.4 Vertical bargraph
Entered from
Circular Trend
mode by means of the down arrow key, or selected from the Root Menu
‘Goto View’ key, this display mode shows the Process Variable (PV) values as vertical bars with faceplates
containing digital values and alarm data. There are two versions, one with faceplates above the bars (1 to
6 channels - fi gure 3.4.4a); the other (with faceplates at the right hand edge of the display - fi gure 3.4.4b)
is used where there are more than six channels.
Note: The description above refers to the 180 mm version of the recorder. For the 100 mm ver-
sion, the faceplates appear above the bars for one or two points, but to the right of the bars for
three or more points.
Operation of the option key calls the Option menu display for this display page, allowing faceplates to be
selected on or off. This feature is available for vertical trend, circular trend and vertical bargraph displays
only.
To call the horizontal bargraph display mode, use the down arrow key. Alternatively, any one of the ena-
bled display modes (
section 4.3.4
) can be selected using the Root Menu, ‘Goto View’ key.
Trend history mode is not available from this display mode.
FACEPLATES ABOVE THE BARS
See fi gure 3.4.4a.
As the number of channels in the display group increases, the bars and their faceplates get narrower,
FACEPLATES AT RIGHT-HAND EDGE
See fi gure 3.4.4b.
As the number of PVs increases, the bars get narrower. As the bars get narrower, so the scale values
become truncated as shown in fi gure 3.4.4b. The bars have a set minimum width, and if the total number
of points in the group cannot be displayed within the width of the screen, a horizontal scroll bar appears,
allowing ‘hidden’ bars to be viewed. Similarly, the faceplates reduce in height to a minimum readable
height. If there are more point faceplates than can be accommodated within the height of the screen, a
vertical scroll bar appears, allowing hidden faceplates to be displayed as required.
