I have the folowing situation:
- There is an Element E in PI System with Atrributes A1 and A2
- The attributes A1, A2 have as DataReference different PI Points
- The type of atributte value is Double
- The application App1 writes to PI and updates(changes, inserts) values of Element E(some or all attrubutes have new values)
- The Application App2 receives notification when element E has changed
I tried to implement this use case in C# using Event Example described in the AF SDK reference. The example is written such that Events occur on the AFDatabase level
and I can not translate it onto level of AFElement. Also, when I try to call FindChangedItems I always get that the number of cahnged Items is 0.
Can someone help me with my problem? Any hint is welcome.
