We have implemented a new control system for the keep track vehicle location and monitor alarm from vehicle's stop. This system contain 2 redundancy servers connected with 69 pcs S7 (s-300) RTU and 13 client workstations running in 7days 24 hours. We discover that the workstations will shown "No connection to data server" in the alarm banner after running a period of time. We have check the database on the WinCC server (which the problem client connected with), and found that the collection of alarm data stopped. The alarm banner on all clients connected with this server were stopped also. But another WinCC server seem running normal as well as the clients its connected with. Many corrective action had been done including: 1. Upgrade the server hardware form PIII 800Mhz to Dual Core2Duo 2. Windows OS upgrade from WINNT 4.0 to WIN2K (Both Servers & all workstations) 3. Enable dual LAN ports and LAN cables between network switch & servers replaced. This new system has been develop since 2004. The first case of the "No connection to data server" reported at Dec/2005, and it seem that we have no idea how to solve it from the problem occur till now. We have done many corrective action but in vain (e.g. exchange the hardware and software, networking etc...). Since this very serious affect our operation andwould any expertget helpto solve this problem? I have captured the diagnostic log for the case occurred on 5 Jun 07 from 13 workstations and 2 WinCC servers. I hope it mayprovide more informationfor analysis.

The data log for the case occurred on 5 Jun 07, including the screen dump for workstation, alarm log forboth servers for your analysis. Furthermore, I have attached the WinCC Application system configuration, export list for test library & alarm logging as well as the diagnostic from 13 workstations and 2 WinCC servers. I hope it mayprovide more informationfor analysis. Here is the Log data for WinCC Server 1 AttachmentSrv1Data.zip (599 Downloads) |

Hello Kant, I see you've posted the diagnose folders, that's good. In the e-mail, I also asked you this, did you look at it? I notice you're using v5.x. V5.0 has a limitation on the amount of messages to be displayed on an alarm window of 10000, and a limitation on the database size of 2GB. This has been improved on v6, where there are no limitations regarding database size (except, naturally, for the hard disk size). You should check the database size... WinCC V5 has two archives, a short-term and a long-term archive. In the Alarm Logging Editor you create these archives AND specify how much data to store in each one. Thread 1, Thread 2, Thread 3, Thread 4. Best regards, Danielle |

Dear Nemo, I tried to capture the "ActionOverflow:more than 5000 Actions to work" problem after rebooting the WinCC server but I can'tfound the same message in the log again but the WinCC's "No connection to data server problem" still exist and need to reboot the server. The recent case occur in 1 Jul 07 1:48 and I have captured the diagnose log for your reference. Is there any method or a piece of program script could capture the element (e.g. in pictures / global script / function) which cause the problem occur and we could further investigate the problem.
Thanks a lot!! Best Regards, Kant AttachmentDiagnose.zip (576 Downloads) |

Dear Danielle, I spend a period of time to inspected the possibility according tothe thread you provided. For Thread 1 : -------------------- I have verified the Text Library content with the Alarm Logging, same alarm message appear in both place. Since we haveonlydefine language in English only, all other language (e.g. German) were blank. The content onText Libraryand Alarm Logging seem in line. I have change one of the alarm message (delete the message content) in text library and let it no in line with the alarm logging deliberately in order to simulate the fault. But I only got a blank message in the alarm banner, the "No connection to data server" message haven't appear. I have read this thread before but I can't locate what is missing in the text library, so I have upload thedump of thecontent for text library and alarm library in previous attachment. And it may give you more information for solving this problem. For Thread 2 : -------------------- Alarm Controlobject seem working well when no this problem occur, it could display all the alarm obtain from S7 RTU. And we running in two redundancy servers while this problem occur, all the clients connected with this server will stopped to collect the alarm and display "No connection to data server" in the alarm bannerbut anther serverstill running well. All the client connected with this another server running normal also. And I believe that Alarm Controlobject should be OK otherwise all the client will display the "No connection to data server" immediately when the project start up. For Thread 3 : -------------------- We tried to search for any error in the RT database using the SCVIEW command from the sybase. No any patency error could be observed and the data logged in the database seem normal. And the database size around 1.1G still not excess2G limit. (see the attachment for the screen captured) For Thread 4 : -------------------- We tried to empty theruntime and the archive database (short-term and a long-term archive) by replacing aclean empty database into the project before and it seem no help on solving this problem. This problem still occur after few day of the action. We also have consider to upgrade the WinCC form V5 to V6, but since manyDLL have already developed using the call by sybase. Reprogramming all the DLL may not possible. All the available patch for WinCC and Windows has be applied, Do any suggest that we could trace the root causeof this problem? Since we could not locate the root cause, so we could not solve it.................. Thanks for the kindly support!! Best Regards, Kant AttachmentDB_Size.zip (500 Downloads) |
