Add tags from a non-grade-based process area. Use the moving average of a process tag as the downtime filter. Configure the Centerline to automatically load the latest data when opened. **Steps:** 1. Open a new Centerline display. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image002_049.png) 2. Right-click on the body of the Centerline and select **Configure**. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image004_041.jpg) 3. Open Tag Browser. Search for the tags that will be added to the Centerline. In most cases, all the tags in a Centerline will belong to the same process area. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image006_035.jpg) 4. Drag the filtered tag list onto the **Tags** tab of Centerline Properties. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image008_020.png) 5. When asked to use this tag’s process area settings, click **Yes**. This applies the [process area](/v1/docs/interface-process) settings of the first tag in the set to the Centerline.

On the **Startup** tab, set the default **Period Type**. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image011_025.jpg) 7. To determine the number of run columns on load, make sure **Filter Runs By** is set to “Run Count” and then change the run count to the desired number. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image013_020.jpg) 8. In the **Misc. Settings** section check **Load Latest Periods on Startup** to automatically load data when the Centerline is opened. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image015_018.jpg) 9. If the process area of the Centerline does not have a filter tag (downtime tag), one can be manually specified for use by the Centerline. Switch to the **Overrides** tab, scroll down, and check **Enable Filter Override**. Leave **Tag** selected. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image017_023.jpg) 10. In the Tag Browser, find the tag to use as the filter and drag it into the **Tag** field. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image019_024.jpg) 11. Depending on the nature of the downtime tag, the configuration of the override will vary. In some cases, the downtime tag has digital values to indicate whether the process is “up” or “down” (0 or 1). In this example, a process tag with continuous values will be used as the filter. Rather than use instantaneous values, a moving five minute time-weighted average will be used. Click in the field and append “/TAVG=5M” to the end of the tag name. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image021_028.jpg) 12. Suppose time should be filtered whenever the moving average drops below a given value (the process has slowed down enough that the data is not valid). Enter this value in the **Filter Below Value** field. In this case, whenever the moving five minute time-weighted average of the tag drops below 15, the Centerline will exclude that time from its calculation of statistics. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image023_023.jpg) 13. On the **Time Periods** tab, select the types of time periods that will be available for selection by the user. Select a time period type in the **Available** panel and then click the **Add** button. Repeat as necessary. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image025_018.jpg) 14. Click **Update**. ![](https://cdn.document360.io/59db2ca4-e512-446a-a143-a7c626447812/Images/Documentation/image027_005.png) 15. Save and close the Centerline.
