Split from Hang WinCC Runtime and server.

Dear ARLS,

What version of WinCC are you using?

Have you looked at the Windows event log on all computers if you see any crash of any applications when scripting stops?

Are there any other errors in the event log around that time?

Dear Kama,

I have the second issue before, and i was using Wincc7.2. my problem was the count of actions per cycle 

and this is the link for this issue

and also you should check your PC hardware, as if your computer doesn't respond that means your kernal has stopped working. I advise you to check the power supply of your computer.

Hi,

there is a monitoring time in each Named connection. if you have 15 named connections you should make it 10 seconds as I remember the default is 0.5 second. you should check Simatic NET v 12 manual
