Hi,

I am new in OSI PI and am learning PI AF SDK. I have created Custom Data Reference using AF SDK 2.8.

This custom DR, do average of two attributes values (SINUSOID, CDT158) and store it into another attribute which is a PIPoint type.

Its working fine but only when I refresh custom DR attribute from PI System Explorer.

I want to update resultant attribute value whenever the values of source attributes (SINUSOID, CDT158) get changed OR in some regular interval. Means how I run this custom DR Logic continuously into PI AF server, as like default Data References (Formula, PIPoint, String builder and Table Lookup).
