Please suggest me, What can i do.

System Configuration:-

1) 500GB Harddisk.

2) 8 GB RAM

3)  Xeon(i 7) Processor

4) 4 Monitor

Dear DheerajMittal,

If I were you, I would write some codes to check whether your WinCC logic is working fine or not. i would start searching for any script code problem or handling of many variables at the same time, what makes WinCC run slower. Another thing, check the folder \Diagnose to find out problems. Good luck! 

But I checked in ApiDiag.exe that is not showing any error.

What code can i used to find problem please suggest me.

Dear DheerajMittal ,

How many tags you are using on this faceplate?

I have faced with the same problem when have used too many tags on my faceplate.
