Hi rcrivi , delete Tag Logging Archive means delete all files into WinCC project folder "...\ArchiveManager\TagLoggingFast" & "...\ArchiveManager\TagLoggingSlow". You can reset to empty archive with "Reset" command located into WinCC Explorer: open Tag Loggin, select Archive, right click on Tag Logging Fast and select "Reset"; same command for Tag Loggin Slow archive. This operation can be performed of line ONLY. When WinCC is in runtime historichal data (.ldf & .mdf files) are used by WinCC. I don't think you can delete this files with WinCC in runtime. Maybe it possible using MSQL database access,but i never tryed it Regards |

Hi rcrivi,
Yes..you need, if you want to do it in RunTime
I absolutely NOT agree, i had to work a lot of in FDA compliant application and this feature is what they ask mostly !!!!. Operation is very simple, you right, ONLY delete few files...and a lot of historychal data
Very simple task often don't need script but need to know well te instrument you are using I used Wonderware too, but i like more WinCC or PCS7, a lil hard for "simple" task and very powerfull for some "NOT simple" tasks...but just my opinion I'm waiting for other solution too...very intresting question Regards |

Hi guys,
I think you boths are right: rcrivi, you right about everybody can reset historichal data: "everybody can deactivate WinCC Runtime". As well as uel123said, WinCC is a development tool to write application final user has to use. It's hard sometimes develop application that are very user friendly, but this is our job. It's true also, who is going to delete critical data has to know what he/she is doing, so the developers could lock actions they can't perform. For example: Lock all key combination (CTRL+ESC, ALT+TAB etc) and set very high level to "Exit Runtime" Button. Only people with high skill/responsability can do that (maybe trace operation in "List Operation" message. In this way "NOT everybody can deactivate WinCC Runtime" and delete historichal data. At the end, try to explain a lil more about your goal, as well as uel123suggested, maybe more people can help you. Regards |
