[snip] The hard drive capacity is limited and if we copy all the data from the backup folder it will be used in very short time. We want to increase the drive capacity by adding another hard-drive for the backup. But the problem with displaying with those additional data would persist as they could not be copied into the CommonArchiving folder because of the hard-drive capacity problem. Is there a way how the backup data that are on another drive and can't be copied into the project folder under the CommonArchiving could still be display in the trending? ------------------------------------------------------------------------------------------ |

Hello JaSemJa First of all you have to understand whats happening if you do that. -> WinCC handles every database segment of the loggings like TagloggingFast, TagloggingSlow and Alarm Logging (and Audit if you have). Every handled database segment in runtime will need systemperformance and will stress the SQL Server process. you should not have much more than 200 single segments connected in Runtime in order to run a performant system. now if you copy segments in the common archiving folder you attach these additional segments to the runtime, so you encrease the number of current attached segments. and if the data stays in the common archiving folder this will happen every time you are in runtime. So this could cause critical problems with SQL and WinCC Performance if you use too much data in this folder. Its only made for explicit needed temporary available data. Another common way to attach only the needed segments temporary you can use this: https://support.industry.siemens.com/cs/ww/en/view/109798671/134765794315 So the three ways are: - Common Archiving - Function buttons in Controls - VB Script I hope this information helps Bye Murof |

Hello JaSemJa every time you atach a backup segment in Runtime it will go to common archiving and will be attached additionaly to the running databased for Taglogging and Alarm logging. If you do not need these segments any more you have to detach it again (for example with the button in the controls) you cannot open or connet the segments from a different location. It will always be added to the project files and then attached in the running SQLServer instance of WinCC runtime. And how you detach the segements is also written in the next chapter of the manual i have send you: https://support.industry.siemens.com/cs/ww/en/view/109798671/96501444875 If it helps I would thankful to get a few stars Bye Murof |
