Create PI point array data references

Create a PI point array data reference to link attributes of elements to arrays of PI points for either reading or writing their values.

1. To configure a PI point array data reference:

   • In the Elements browser, select the desired element.

   • In an element template, select the desired element template in the Library browser.

2. In the Attribute or Attribute Templates tab, select the attribute.

3. In the attribute configuration panel, choose PI Point Array from the Data Reference list.

4. Click the Settings button.

5. In the PI Point Data Array Reference window, leave the default server, or choose a different Data Archive from the Data server list.

   Note: If the desired Data Archive does not appear in the list, click and select a Data Archive from the PI Data Archives window.

6. In the Tag name field, choose from the following actions:

   • To enter PI points directly, enter point names separated by the pipe symbol (|). For example:

     CDM158|CDT158|SINUSOID

   • To search for PI points, click and enter search criteria in the Tag Search window. Select multiple PI points on the selected Data Archive.

7. Optional. Specify the units that the referenced PI points use. See Units of measure (UOM).

8. In the Value retrieval methods section, specify how the attribute gets its value. For example, the attribute value could be the same as the point values, or it could be a result of a calculation on the point values. See Configuration of retrieval methods.

9. Use the Read Only check box to specify whether you want PI AF to write the attribute value back to the source points. By default, PI AF does not write data to the referenced PI points (the Read Only check box is checked). See Attribute value updates.
