The alarm object is generally used to enunciate alarms to the operator. While the display characteristics

of this object is configurable, it is generally displayed as a button that changes colors to indicate the

highest state of the alarm(s) in the alarm group it is monitoring. The following indicates the priority of the

alarm states and the default colors associated with these states.

• Highest (Red) - Unacknowledged Alarms Exist

• - (Yellow) - Acknowledged Alarms Exist

• Lowest (Green) - No Alarms Exist

To view, acknowledge and/or clear alarms, the operator must access the alarm viewer. This is

accomplished by touching an (enabled) alarm object. When accessed, the alarm viewer is displayed as

pop-up alarm viewer dialog similar to that shown in Figure 10.6.

The currently selected entry is indicated by a yellow highlight which can be moved up or down by

touching the arrow buttons or by directly touching an entry. If more entries exist than can fit on the page,

a scroll bar is displayed on the right side that also indicates the current relative position.

The current state of the displayed alarm is indicated by its color and optionally by an abbreviated indicator

after the date/time stamp (ALM, ACK, RTN). The operator can acknowledge an alarm by selecting it

from the list and touching the ACK button. The operator can also clear an alarm if that function is enabled
