Configuring Filters for Alarm Grids and Charts

In the Configure Alarm Filter dialog box in AlarmWorX64 Viewer, you can create criteria that define a filter or range of values under which a chart's or grid's data is affected. A filter is an expression that must be satisfied for an alarm to conform to that filter. It creates a condition for displaying or working with data, and can be used in several places in an alarm viewer. Once you define a filter for one context, it becomes available in all other contexts, too. For example, if you define a filter for use in a chart, you also use that same filter for translating text.

System filters

System filters are predefined filters which are frequently used or that provide examples of filters that you can create for yourself. Each predefined filter is made up of a field and a logical operator, plus a value. System filters include the following values (for help understanding some of these values, refer to the Columns topic):

• None

• Severity <= 100  (other values are 200, 400, 500, 600, 800, and 1000). Shows alarms whose severity is equal to or greater than a specified value.

• NewState <= 1  (other values are 3 and 7). Shows alarms whose new state is equal to or greater than a specified value.

• Quality == 192  (other values are 0, 64, 4, 8, 12, 16, 20, 24, 28, 68, 80, 84, 88, and 216). Shows alarms whose quality field is equal to a specified value.

• Category == 0  (other values are 1, 2, and 3). Shows alarms whose category field is equal to a specified value.

• EventType == 1  (other values are 2 and 4). Shows alarms whose event type field is equal to a specified value.

• Plus the names of other filters that you have defined in the alarm display.
