Tag receiving wrong values from PI AF Analysis

     I'd like to thank in advance any help you guys can provide.

       

     I'm having an issue with a pit ag and i'm unable to work it out.

    

  • I have created an event triggered analysis that takes a tag called "trigger.tag" as a trigger for execution
  • That analysis writes the result of the calculation (tagtot of another pi tag) to another tag called "analysis.tag"
  • When i check the data written to the "analysis.tag" i see that some of the values have a trigger at the exact time which is correct,
    but some other values have no trigger, also they are written 30 seconds before the next value that has a trigger.
  • I'd like to know how to fix this behaviour. Is it because of the tag configuration?.
  • I've made many tests over the past 2 weeks and i'mn unable to fix this issue.

 

     Here's an example of what is going on with my tags.


      

     I hope you can help me.

     Thanks again.

    

     J.
