Figure 11.7: 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 Clear 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 that 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.

Media

removable media device and allow access to its file structure. The removable media object is displayed
as a button that changes colors to indicate the current state of the removable media device. The following
indicates the device states and the default colors associated with these states.
• Highest (Red)
- Device Error

(Yellow) - Device Full (threshold adjustable)
