Actually it is very easy to do with SQL however this is no good for WinCC as it does not use SQL !! The topic of accessing tag logging values directly has been asked many, many times on this forum - just use the search box at the top of this page. In a nutshell, you need a WinCC option to access the WinCC database values. Your choices are the Connectivity Pack, IndustrialDataBridge or DataMonitor. More information on these options can be found at http://www.siemens.com/wincc/options |
