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.
