Is there any way to subscribe and receive PI points attributes changes via Pipe like in PISDK?
Yes, it could be. If you have the PI SDK user menu, please go to see PI-SDK Programming Reference -> EventPipe -> Event Pipe Object. There will be the detailed explanation.
Hello Xi Wang, and thanks for the reply.
I already developed the PISDK version that uses EventPipe object.
My goal is to create same application via AFSDK.
Sorry for the misunderstanding, but it could be also. Do you have the new version AF SDK (AF SDK 2.5 or later) please? If so, please go to see Namespaces -> OSIsoft.AF.PI Namespace -> PIDataPipe Class. There is an example on how to use PIDataPipe function, and in this example, it has shown how to put attributes of PI points into one Data Pipe.
AF SDK 2.5 does not have a mechanism to sign up for PI Point configuration changes.
AF SDK 2.6 will provide this via PIServer.FindChangedPIPoints.
