Alarm displays only include those alarms to which a user and ViewX or WebX client have access. Additionally, a Default Alarm Filter can optionally be specified on a per user basis. Such a Default Alarm Filter can be used to further restrict the entries that are included in Alarms Lists and the Alarm Banner, to just those alarms that are of interest to that particular user. A system administrator or high-level engineer typically configures any such Default Alarm Filter whenever a new User Account is added to ClearSCADA, by specifying an Alarm Filter String for that user (see Specify a Default Alarm Filter).
If required, you can use the Filter window to temporarily filter the entries further, so that only a subset of alarm entries is included in the Alarms List or Alarm Banner. For example, you might want to temporarily filter an Alarms List so that it only provides information on alarms that have High severity. If your User Account allows you to filter entries in the Alarm Banner, ClearSCADA might be configured to automatically disregard any such filtering as soon as your User Account’s Banner Filter Timeout period is exceeded.
If your User Account is assigned a Default Alarm Filter, you can also use the Filter window to temporarily adjust the default filters, so that the alarm displays include further alarms to which your User Account and ViewX or WebX client have access.
The instructions below tell you how to use the Filter window to temporarily filter the entries in an Alarms List or the Alarm Banner.
