PI OPC Watchdog tag has value with "Scan off" ,where tag attribute is set to scan on.


But when I have logged into interface machine, I have observed that monitoring tag showing status as "Incorrect" where previously which is working fine.

Please find the screenshot with more detail's.

I have the solution for this by right clicking on it and say correct , then watchdog tag starting working fine as normal.


But here we want to know why this kind of issue will come up ?


Thank you,

Prasad. N
