Hi,

 

I've built an analysis that iterate through an AF table, get PI tag names and test theirs current value. I was getting the tag name right with an table lookup attribute but i found out that the PI Point attribute don't update its data reference with the new tag name when the analysis call. After some research, System explorer user guide specify PI Point data reference are only updated at design time (like a refresh in PSE).

 

Is there any other method to either change the data reference of an attribute or read a PI tag value from an analysis without using attributes...

 

I guess my last hope would be to code a custom data reference ?

 

Thanks.
