BAR GRAPHS SCREEN
The ST-72 Bar Graphs screen shown in Figure 1-4 allows 16 channels to be viewed
simultaneously. Both engineering units and bar graph values are indicated in real time.
Lines across the bars indicate the alarm trip points making it easy to identify channels
near alarm. The bar graph alarm lines have colored triangles on the bottom that
indicate alarm level and high or low trip for each alarm. A triangle that points right
represents a high trip alarm and one that points left represents a low trip alarm. When
a channel reaches alarm state, the bar graph changes to the color that represents that
alarm level and flashes. Once the alarm is acknowledged the bar stops flashing. If there
are more than 16 channels active the scroll bar along the right side of the screen
indicates channels not in the viewing area. If one of the channels not in the viewing
area goes into alarm the scroll bar arrow flashes the corresponding color of the alarm
indicating which direction the user must scroll to display it. This is demonstrated by the
top scroll bar arrow below.
