4.3.2.3 Status Area
Each point on the Group Display contains a Status area, located directly below the point description (Fig.
Figure 4-8 ). The status area is composed of two lines and an indicator area.
4.3.2.3.1 Status Messages
Point status messages are displayed in the first line of the Status Area. Depending on the type of point dis-
played, this message can be an alarm or other condition of the point. The area number is displayed to the
right of the alarm status descriptors.
4.3.2.3.2 Mode Message
The second line of the Status Area indicates the current mode of the point; e.g., Auto or Man.
4.3.2.3.3 Alarm Indicator
In addition to a status message and mode, each point’s Status Area contains an ACK [Acknowledge] but-
ton, located on the left side of the area. This button appears when an unacknowledged alarm exists for the
point. The color of the button reflects the current status of the point:
• red for hihi or lolo alarm
• yellow for hi or lo alarm
• green for normal
Click ACK to acknowledge the alarm or, if the Operator Window containing the alarm indicator has key-
board focus, press
A LT -F10 on the keyboard to acknowledge all points in the group which are in alarm.
If no unacknowledged alarms exist for the point, the ACK button is not visible.
4.3.2.4 Process Display Area
Directly below the status area for each point on the Group Display, the process display area is arranged in
one of several forms, according to the type of module being described.
Analog points are displayed in a form which includes a process bar in the process display area. The length
of the process bar corresponds to the value of the Process Variable (PV) atom and is displayed as a per-
centage of full scale; the upper and lower limits of the range of the Process Variable are reflected in the val-
ues at the top and bottom of the scale located at the left of the process bar. These limits are presented in a
fixed precision format, with one digit to the right of the decimal point.
Below the process bar, the data displayed includes the values of the Process Variable for all types of ana-
log points, the value of the Setpoint and setpoint controls (if applicable), controller output indicator, the
value of the Output, and output controls (if applicable). The number of digits used to display a value
(including the decimal point) and the size of the group display (whether it is configured for four, six, or eight
