If you have not already done so, insert an Alarm Analysis object into your display. How?
If you have not already done so, specify a data source. How?
NOTE: The columns that you specify when setting the data source will appear in the Columns list on the Filter tab.
To add a filter condition, from the Columns list, select the column you want to set a condition for and click the Add Filter Condition button. The dialog box associated with that column appears. For example, if you selected Alarm Status, then the Add Alarm Status dialog box will appear.
Select the operator to use in the condition. The available operators depend on the type of column selected.
Select the value to use in the condition. The types of values available depend on the type of column selected. For example, for Alarm Status, a drop-down list of the statuses is provided. For Native Date/Time In, you can select the Absolute or Relative time and then make the appropriate time selection.
If you are specifying a parameter as a filter condition, select the Link to Parameter check box and select the filter parameter from the drop-down list. For date-type columns, only the date filter parameters are available; for all other columns, the non-date filter parameters are available.
If you have specified a parameter as a filter condition, you also have the option of specifying a default value to use for the parameter. Click the Edit Default Parameters button to open the Edit Filter Parameters dialog box. Enter the default value in the Parameter Value field beside the parameter name. For date-type parameters, you can click the calendar button provided.
Click OK. The new filter condition appears in the Display Alarms Where list.
If you want to add more than one filter condition, repeat step 3. When the additional filter condition has been added, it appears in the Display Alarms Where list and is separated from the previous filter condition by the AND operator.
TIP: If you want to add a filter condition above another filter condition, select the filter condition in the Display Alarms Where list and click the Insert Filter Condition button. Repeat step 3 to configure the condition.
If you want to change the operator, select the new filter condition in the Display Alarms Where list, and select the OR or NOT operator.
TIP: If you are writing a
complex comparison, make use of the brackets. An example of this
(Alarm Priority = "LOW"
AND Alarm Status = "LO")
OR (Alarm Area IN "D"
AND Alarm Status = "HIHI")
This creates two sets of conditions; the object will show data if the Alarm Priority is set to LOW and the Alarm Status is set to LO, or if the Alarm Area is set to "D" and the Alarm Status is set to "HIHI". Using brackets is important when combining different conditional operators to preserve the logic.
NOTE: If you want to make changes to a filter condition, select the condition in the Display Alarms Where list and click the Modify button.
Click the Save button to save the current changes, or if you would like to resuse the current filter conditions again in the future, click the Save As button and provide a new name for the filter.
