Hello Everyone,

I also facing the same problem of " No Connection with Data Server " error in WinCC  Server.

I am using PCS7 V7.0 and the OS of WinCC Server is Windows Server 2008 Standard Edition. The problem is whenever I activate the project in Wincc Server ,I can see all the alarms and everything but after 10 second all the alarms are gone and " No Connection with Data Server " showing at the alarm pages.

One of the reason I found that the service CCAlgRtServer.exe is stops suddently after activating the wincc server project and after that all the alarm are gone from Wincc server.

Can anybody suggest me the reason for this sudden stopping of CCAlgRtServer.exe  and how can I solve this problem.Thank in advance.

Best Regards.

Shambo.

Hi

Have you tried to reset the WinCC connection using the Reset_WinCC.vbs in C:\Program Files\Siemens\WinCC\Bin directory?

If you run this script then the connection to the database is reset and when you restart WinCC, it should be reconnected.

Dear Team,

Is the problem solved?

Hi AEmerick,

Do u have original backup? Put it in runtime. Now u can see current alarms and trends but u will miss old data. If the problem persists, re-install WinCC.

I faced that problem but I solved that.

Go to project folder. There is a folder named to your server .Enter and find package folder .delete ".pck' file .Then go to the wincc project ,In the project there is a option server data. right click that option . delete the server package .pck file. then  agai right click creat server data. restart wincc
