We have WinCC v7.4 SP1 Upd11 installed on the virtual machine, which is connected to one S7-315 PLC, collects data from it and maintains an archive of these data. A small visualization of current data has also been made, trends and alarm messages are displayed. Other software "1C" is connected to the MSSQL database with archive data and pulls the necessary data. The problem is that after an indefinite time, trends and alarm messages cease to be displayed. At the same time, data from the PLC is written to the archive, 1C quietly pulls them out of the SQL database. I also noticed that in the Simatic Shell at this moment the project disappears. The problem with trends and alarms is solved only by rebooting the virtual machine. In this case, after a reboot, the trends can display all previous archive data. Initially we have installed WinCC v7.4 SP1 Upd9 on Windows Server 2012 R2 - there were exactly the same problems. Then we have installed WinCC v7.4 SP1 Upd9 on Windows 10 - the same thing. Updated WinCC to WinCC v7.4 SP1 Upd11 - the problem has not been resolved. Yesterday I have checked the Logs (inside the folder "C:\Program Files (x86)\Siemens\WinCC\diagnose\"), and I found only one error - "CCMcpFile::ReadFile error on CMcpFileReader::ReadMcpFile" (you can see full log in the attachment. There the virtual machine was rebooted at 10:24, and this error appear at 12:03) Attachmentdiagnose.zip (349 Downloads) |
