Hi Mehrnoosh, well, you should know, that using rawdata tags for this amount of data in such short time periods will cause a lot of communication load and certainly reduce dramaticly your WinCC permformance. => I can NOT recommend this http://support.automation.siemens.com/WW/view/en/21916098 The length of your rawdata is depending on your S7-CPU, please check this in the FAQ mentioned above and your WinCC help. => you should really check, whether it´s necessary to exchange so many data between S7 and your database... nemo |
