Hi, We're running a WinCC project that was originally developed in WinCC v6.xx and later-on upgraded to WinCC v7.2. The company that originally did the development and past upgrades does not exist anymore and since we were forced to move over to Windows 10, it was necessary to upgrade the project to WinCC v7.5. Because there was no support anymore and I already did a couple of changes to the project over the past years, I also decided to perform the upgrade from v7.2 to v7.5 myself, which in general looked successful. The problem after the update however, is that some of the pages seem to ‘freeze’ when they’re loaded. At this point the animations don’t show current status and it is not possible to navigate to another screen all the although the animation behind the button if I click it is shown. After a while this sometimes solves itself but mostly not.Often this also occurs if I navigate back to a screen that was visited before and at first load was working fine. The project is full of C-scripting & VBS, often used instead of simple Standard functions, I guess mostly for ‘knowledge protection’. If I debug the project using apdiag.exe, it continuously shows me Error on unknow Tags, eg.: SystemTime: (ThreadId 12332) 2020-03-30 14:39:24.528 dwErrorCode1: (ThreadId 12332) 1007006 dwErrorCode2: (ThreadId 12332) 3 szErrorText: (ThreadId 12332) Tag unknown, timeout or conversion failed szApplicationName: (ThreadId 12332) GSC_RT bCycle: (ThreadId 12332) cycle szFunctionName: (ThreadId 12332) @e74 szTagName: (ThreadId 12332) "a_alt_pfa" dwCycle: (ThreadId 12332) 0 szErrorTextTagName: (ThreadId 12332) Tag deliver status status: (ThreadId 12332) 0x800 dwParamSize: (ThreadId 12332) 0 szErrortext: (ThreadId 12332) Tag not found SystemTime: (ThreadId 12332) 2020-03-30 14:39:24.822 dwErrorCode1: (ThreadId 12332) 1007006 dwErrorCode2: (ThreadId 12332) 2 szErrorText: (ThreadId 12332) Tag unknown, timeout or conversion failed szApplicationName: (ThreadId 12332) GSC_RT bCycle: (ThreadId 12332) cycle szFunctionName: (ThreadId 12332) @e74 szTagName: (ThreadId 12332) "Ausgang_PFA" dwCycle: (ThreadId 12332) 0 szErrorTextTagName: (ThreadId 12332) OLE conversion failed dwParamSize: (ThreadId 12332) 0 szErrortext: (ThreadId 12332) OLE conversion failed If I lookup these tags, they always appear to be strings that are used in one of the C-Script. So, I let the ‘global script inspector’ check the scripts, there are no errors just a lot of warnings (‘MessageBox’: this call can block the execution of the script in service mode.) I’ve included an example of one of the C-functions as attachement. Can anyone tell me what is wrong here? Is WinCC v7.5 handling strings differently that v7.2? Or should the strings in Function-calls be handled differently in WinCC v7.5? Thanks in advance. a WinCC Novice. AttachmentFunction.txt (126 Downloads) |
