Supported modifications for PI Connector Relay

Add custom PI AF attributes

You can add custom attributes to the elements that were generated by the relay. To enable the ability to add custom attributes, perform the following steps:

1. Open PI System Explorer and open the PI AF database associated with the relay.

2. In the Elements menu, find the element you want to modify and determine the template from which it is derived.

3. Select Library, and then expand Templates > Element Templates and select the template from step 2.

4. On the General tab, select the Allow Extensions check box.

5. Return to the desired element in the Elements menu and add the custom attributes.

   Note: Any custom attributes that are added cannot be configuration items; that is, the Configuration Item check box must be deselected for the attributes.

Custom attribute templates can also be added to an element template, as long as Allow Extensions is checked on the element template and the Configuration Item checkbox is not checked for any attribute templates that were added.

PI AF template modification

Several modifications to PI AF element templates that are generated by the relay are allowed. You can add Extended Properties to the element template, assign a category to attribute templates, and check the Allow Extensions checkbox. You can also add PI AF analysis rules directly to an element or an element template.

PI point configuration modification

It is possible to modify selected point attributes after they are created by the relay.

• Modification of the compression settings attributes

• Modification of PI point security settings

• Attributes like Step, Scan, Archiving, Span, Zero, and Typical Value

  Note: Any point attributes synchronized by the connector will be reset on connector restart.
