Alarm Viewer
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 14.6.

Alarm Viewer
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 in
the alarm object. If not enabled, the
C
lea
r
buttons are grayed and do not respond to touch. Once view
operations are complete, simply touch the
Esc
button to remove the pop-up alarm viewer.
NOTE:
OCS registers %SR181 and %SR182 are available for ladder use, which indicate presence of
unacknowledged or acknowledged alarm (respectively). The screen designer may implement these
registers to switch screens or activate the beeper to attract the operator’s attention.
