Alarm Filter

You can filter the data according to the conditions on the control. The historical alarm will only display the alarm information in the alarm history library under the current node, and the historical alarm data at the remote node will not be displayed.

Both editor and running pages support data filtering.

Filter Data On Editor

Data filtering can be performed in the "Properties" -> "Filter" of the control. After the filter are set here, the data is filtered and displayed according to the set conditions on the running page.

Note: The enable/disable of options in the filter panel only indicates whether data is displayed in the control, but does not mean that the data is not queried. It will not affect the enable/disable status of options in the filtering criteria. For example, in the filtering criteria, only 'Active, Unacked' is enabled, but in the filtering panel, all options are enabled.
