I've created a custom DR and use the GetValues override to expose my custom data to PI consumers. It works in Process book and AF System Explorer. However When calling my DR from DataLink i get the following.
|Data item not supported by function|
I then add:
public override Data.AFDataMethods SupportedDataMethods
Data.AFDataMethods supportedDataMethods =
the error changes to:
Unable to convert a Variant containing a time representation to a double.
Please note it does work in process book and systems explorer, any ideas what additional fluff is required for the datalink ( Compressed Data)to attach correctly?
