I have a PE with " IF (...) THEN (...) ELSE NoOutput() ": every time that I attend no ouput, insteasd of no ouput, I find my PE valuated in archive with "No Sample". How can I solved it? (PI Version is 3.4.380.70)
Can I provide more information?
We missed answering your initial question. Please accept our apology.
Where do you see "No Sample"? Is this when evaluating your Equation within PI Performance Equation builder add-in for PI SMT?
If so, please note that "No Sample" indicates that based on the current evaluation of the equation no sample would be written to the archive. You should indeed see no event being generated when the equation evaluates to NoOutput().
first of all thanks for your help. I can see"No sample" using Archive Editor of PI SMT; this value is recorded in archive for my tag.
this is not what I am used to. Let's not loose additional time. You'll be contacted by an OSIsoft Technical Support representative.
7855OSI8 - Improper handling of NoOutput().
the target pi server version of fix is 3.5
I am getting my formula working (using 3.4.395.11) - beta version
using 3.4.385.77 - No Sample problem, but No Sample sates are not archived
using 3.4.395.16 - No Sample preblem, but No Sample sates are not archived
Event=Trigger_no_output, if tagval('Trigger_no_output','*+1s')=0 then nooutput() else if tagval('Trigger_no_output','*+1s')=prevval('PE_no_output','*-1m') then nooutput() else 'Trigger_no_output'
