or F6 function key or a pushbutton with the <DIALOG>ALMGROUP keymacro. An Alarm Group is typically a process unit in a multi-process plant.
An Alarm Group Display summarizes alarm events for a fixed and limited number of tags (100 tags maximum in an Alarm Group, up to 9999 Alarm Groups). In contrast, the Alarm Summary displays all active and unacknowledged alarms in reversed chronological order.
Alarm Groups can be configured in any logical arrangement. These are user configurable.
The information provided for each tag includes the alarm priority, date and time of the alarm, alarm type, Alarm Limit, value, and status of the alarm.
The Alarm Group Displays use a pre-built template display. Alarm Groups are easily configured, by typing the Tagname in a list. Alarming does not need to be enabled to add a tag to an alarm group.
Alarm Disable/Enable pushbutton is provided on the Alarm Group. This is intended to allow a operators to Disable Alarms for a Unit that is shutdown or out of service, thereby eliminating nuisance alarms.
The Alarm Group List is a Popup Dialog Box showing all configured Alarm
Groups.
The Alarm Group List can be viewed from the Toolbar icon or F6 function key or a pushbutton with the <DIALOG>ALMGROUP keymacro.
The Alarm Group List can also be called using the Right-Click Menu
(Right Click->Goto->Alarm Group)
and from the Point Goto Dialog Box. An alarm group can be called directly from a Pushbutton with the <GOTO>ALMGROUP=group number keymacro.
Power Users, General Users and the admin account can view Alarm Groups through a Web Browser. (Restricted users cannot view Alarm Groups through a Web Browser). All users can view Alarm Groups locally on the SCADA node using ViewDAQ.
The Alarm Group Display is a pre-built template display supplied with Web Access. It can be customized by engineers and technicians using DRAW. How your Alarm Group Colors, Flashing, Fonts, etc. behave may vary based on how (or if) the Almgrp.Bxx (and Almgrp.dxx) on your system is modified.
Pressing the Alarm Enable /Disable pushbutton will disable alarming for the selected tag (temporarily).
The alarming will be disabled until the Alarm E/D pushbutton is presses again, the .ALMED tag field is changed or the SCADA node Restarts.
