ACE Output tag is writting value -2147219968 on PI Server

Question asked by rahulmittal99 on Mar 16, 2018

I have a ACE calculation, which averages value of the tag over past 24 hours. One input tag, one output tag.

 

The calculation was running fine till date, but today I saw tag having value -2147219968, which was strange. Generally the value for my tags range from 180 to 250.

 

I believe it is some kind of system error value written in ACE PI tag, but couldn't find much details on this over techsupport site and Google. So need the help from forum.

 

Please let me know if more details are required./
