Query alarm history

You can query alarms and events to return the alarm history for a tag. You can further scope the query to only return the tag values that are beyond an alarm limit. For example, if the Hi alarm limit for the ReactLevel tag is 1800, the alarm history can include all values that were above 1800 Hi limit.

To view alarm history

1. In the Query Type list in the toolbar, click Alarm history.

2. If you want to only retrieve alarm history for particular tag(s), use the Tag Picker to select one or more tags. For example, if you want to search for alarm history for all analog tags, select the All Analog Tags public group and then select all analog tags in the Tags pane.

3. In the Columns pane, click on each tab and configure the parameters for the query:

   • See Columns Tab.

   • See Time tab options.

   • See Use the Format tab.

4. To view the results, click the Data tab in the Results pane.
