    Retrieve a PI Point String value at the start of an event frame

    simon.willis

      Hi All,

       

      I have a string value which essentially represents a batch. When the string changes, I have configured AF to close an event frame and start a new one. The problem I am seeing is that the event frame attribute always seems to show the string value at the END of the event frame. No matter what I do with the value retrieval settings, there is no difference.

       

      Here is my PI point. Notice is changes value at 1am

      Relevant event frame is generated

      Here is the value that is retrieved.

      I am starting to think that AF ignores the value retrieval settings for string PI points. Does anyone have any ideas?

       

      Thanks very much.
