Define whether the Visible Time is used as the Active Alarm Time
You can use the Geo SCADA Expert Server Configuration Tool to enable and disable the Use Visible Time as Active Alarm Time feature.
The Use Visible Time as Active Alarm Time feature is designed for use on systems where alarms are suppressed (see Alarm Suppression in the Geo SCADA Expert Guide to Alarms). It sets Geo SCADA Expert to show formerly suppressed alarms near the top of the Alarm Banner and Alarms List.
By default, alarm displays such as the Alarm Banner and Alarms List show alarms according to the State, Severity and Time values of the alarm. This means that new alarms are usually displayed near the top of the Alarm Banner or Alarms List, where they are prominent.
When an alarm is suppressed, it is raised in the same way as any other alarm, but it is not shown on the various Alarm Displays. When a suppressed alarm becomes unsuppressed, it is shown on the Alarm Displays, but as this may be some time after the alarm was generated, it may not be shown at the top of the list. This can be a concern on systems with a high number of alarms, as when alarms become unsuppressed, they could be too far down the list of alarms to be noticed immediately.
To avoid such a situation, you can enable the Use Visible Time as Active Alarm Time feature. With Use Visible Time as Active Alarm Time enabled, Geo SCADA Expert orders suppressed alarms according to the time at which they become unsuppressed, instead of the time at which they were generated. This means that when a suppressed alarm becomes unsuppressed, it is treated as a new alarm and is displayed near the top of the Alarm Banner and Alarms List.
A point alarm is raised at 13/07/2010 10:50:48.249 and is suppressed. As such the alarm is not shown on the alarm displays.
The alarm is unsuppressed at 14/07/2010 08:30:00.000 and is added to the Alarm Banner and Alarms List.
The alarm appears as if generated at 14/07/2010 08:30:00.000 (the time the alarm became unsuppressed), and appears near the top of the list.
To define whether the Use Visible Time is as the Active Alarm Time feature is enabled:
- Access the Geo SCADA Expert Server Configuration Tool (see Accessing the Geo SCADA Expert Server Configuration Tool).
- Expand the System Configuration branch.
- Select Alarms.
- In the Use Visible Time as the Active Alarm Time section, either:
- Select the Enabled check box to set Geo SCADA Expert to order formerly suppressed alarms according to the time at which they became unsuppressed (instead of the time they were originally generated).
Or:
- Clear the Enabled check box to configure Geo SCADA Expert so that it orders suppressed alarms according to the time at which they were generated. This may cause suppressed alarms to appear some way down the list of alarms when they become unsuppressed.
NOTE: When you select or clear the check box, you then need to restart all ViewX clients to effect the change.
- Select the Enabled check box to set Geo SCADA Expert to order formerly suppressed alarms according to the time at which they became unsuppressed (instead of the time they were originally generated).
- Right-click on the system icon in the tree-structure, and select the Apply Changes option to apply the changes.
