Hi Everyone, I hope you are doing well! 

 

I have some troubles with a PE calculation, here's the matter:

I receive information in a tag on 5 minutes spans, such tag sometimes gets behind and I get two values instead of one. Ex:


That tag is an accumulated value, so in my PE I subtract the current value minus the previous  value:

I would appreciate your help, and if you need more information please let me know.

 

Thank you in advance!
