The Alarm Summary shows a list of Current Alarms and Unacknowledged Alarms.  Each time an Alarm occurs, a line is entered in the Alarm Summary describing the alarm.  Acknowledgement by the operator changes the color (or flashing color) to indicate Acknowledgement.  As alarms return to Normal, they disappear from the Alarm Summary (if they have been acknowledged by an operator or user). This is similar to Alarm Monitors in control rooms commonly associated with Distributed Control Systems (DCS).

Figure 7.1 Alarm Summary

The Alarm Summary Display can be viewed from the Toolbar icon  or F5 function key or a pushbutton with the < <GOTO>ALMSUMMARY keymacro.  The Alarm Summary can also be called using the Right-Click Menu (Right Click->Goto-Alarm Summary) and from the Point Goto Dialog Box.

Power Users, General Users and the admin account can view the Alarm Summary through a Web Browser. (Restricted users cannot view the Alarm Summary through a Web Browser). All users can view the Alarm Summary locally on the SCADA node using ViewDAQ.

If there are multiple alarms for a Tag (e.g. High  and  High Deviation), the Higher Priority Alarm appears. There is an Alarm Precedence: 1) Hi-Hi and Lo-Low 2) Hi and Lo, 3) ROC and  lowest 4)Deviation Alarms.  Alarm Ack only acknowledges the displayed alarm.  If there are multiple alarms for a tag, the next Alarm will appear immediately after the Alarm Ack.

The Alarm Summary is a pre-built template display supplied with Web Access. It can be customized by engineers and technicians using DRAW.  How your Alarm Summary Colors, Flashing, Fonts, behave may vary based on how (or if) the Almsum.Bxx (and Almsum.dxx) on your system is modified. 

Acknowledge All

Pressing the Acknowledge All button will acknowledge all active alarms on the SCADA node. 

If a tag's current value has triggered multiple alarms (for example, low-low and low alarms) then the next lower priority alarm will appear.

Acknowledge Screen

Pressing the Acknowledge Screen button will acknowledge all active alarms Displayed on the screen. 

If there are more than 17 alarms (i.e. the number that will fit in the Alarm Summary) only the first 17 alarms will be acknowledged. The user must use the Scroll Down (or Scroll UP) buttons to view additional Alarms, which will be unacknowledged.

Similarly, if the Alarm Filter is enabled, only the displayed alarms will be acknowledged.

Acknowledge Tag

Pressing the Acknowledge Tag button will acknowledge only the selected tag.  To acknowledge only one tag on the Alarm Summary:

1.      Click on the Tagname (or anywhere on that line)

2.      Click Acknowledge Tag

Acknowledge Group

Pressing the Acknowledge Group pushbutton will acknowledge all active Alarms in the Alarm Group of the Selected Tag. See Alarm Groups for information about building Alarm Groups.

Filtered # of Alarms

Indicates the  total number of alarms in the Alarm Summary display after the Alarm Filter has been applied. 

For example, if Alarm Priority 5 alarms are filtered, and there are 10 Alarms with a priority of 5, then the
 Total Number of Alarms = Filtered # of Alarms + 10

 See also, Alarm Filter.

Total Number of Alarms

Indicates the  total number of alarms on the SCADA node, ignoring any Alarm Filter.
