Establishing Downtime Faults

Downtime faults are used to automatically assign reasons to downtime records for a given historian result. When a downtime event is recorded and the value of the historian tag matches the fault value, the associated reasons are assigned to the downtime event.

You must assign cause reason trees. See Attaching Reason Trees to Downtime Locations.

To configure downtime faults

  1. Expand Plant Model.

  2. Expand the department and production line to which the desired production unit belongs.

  3. Right-click the production unit and select Configure Events on <production unit>. The Event Configuration dialog box appears.

  4. Under Events Enabled On This Unit, select Downtime. If you have not assigned a downtime event to this unit, see Adding and Configuring a Downtime Event.

  5. Click Event Properties. The Downtime Configuration dialog box appears.

  6. Click the Fault Translation Table tab.

  7. Click Add. A new row is added under Fault Translation For Detection Model Output.

  8. In the Fault column, type a fault value. The fault value must match a value that will be returned by an historian tag (if using model 200) or a fault value identified in a script (if using model 210 or 211). Fault values must be unique on this production unit.

  9. In the Fault Name column, type a name for the new fault. Fault names must be unique on this production unit.

  10. Select the production unit from the Location list. If the production unit has child units configured, the production unit and its child units will be available in the Location list.

  11. In the Reason1 column select a reason from the list. The contents on the list will depend on the reason tree selected on the Cause Reason Trees tab. Depending on how the reason tree is configured, you may select subsequent reasons for Reason2 through Reason4.

  12. If necessary, click Remove to remove the selected row.

  13. Click the Close button to save your changes and close the Downtime Configuration dialog box. You will return to the Event Configuration dialog box.

Importing and Exporting Fault Tables

  1. To import a list of faults, click Export to create an Excel spreadsheet with the appropriate formatting for import.

  2. Fill in the exported Excel spreadsheet with the new faults and default location and reasons.

  3. Save the Excel spreadsheet and leave it open.

  4. Click Import to import faults from the spreadsheet. The import feature will import the active spreadsheet.

  5. New fault values are appended from the import, and existing fault values do not need to be included in the import.
