A "WinCC OnlineTrendControl" with the name "Control2" is inserted in the process picture in the Graphics Designer. A button is inserted in the Graphics Designer. You have configured, for example, the event "mouse click" with a C action and the following script for the button. Example of VBS: //create reference to new window, time and value axis SetPropChar(lpszPictureName, "Control2", "TrendWindowAdd", "myWindow"); SetPropChar(lpszPictureName, "Control2", "TimeAxisAdd", "myTimeAxis"); SetPropChar(lpszPictureName, "Control2", "ValueAxisAdd", "myValueAxis"); //assign time and value axis to the window SetPropChar(lpszPictureName, "Control2", "TimeAxisTrendWindow", "myWindow"); SetPropChar(lpszPictureName, "Control2", "ValueAxisTrendWindow", "myWindow"); //add new trend and assign properties SetPropChar(lpszPictureName, "Control2", "TrendAdd", "myTrend1"); SetPropWord(lpszPictureName, "Control2", "TrendProvider", 1); SetPropChar(lpszPictureName, "Control2", "TrendTagName", "Process value archive\\PDL_ZT_1"); SetPropWord(lpszPictureName, "Control2", "TrendColor", RGB(255,0,0)); SetPropChar(lpszPictureName, "Control2", "TrendTrendWindow", "myWindow"); SetPropChar(lpszPictureName, "Control2", "TrendTimeAxis", "myTimeAxis"); SetPropChar(lpszPictureName, "Control2", "TrendValueAxis", "myValueAxis"); //add new trend and assign properties SetPropChar(lpszPictureName, "Control2", "TrendAdd", "myTrend2"); SetPropWord(lpszPictureName, "Control2", "TrendProvider", 1); SetPropChar(lpszPictureName, "Control2", "TrendTagName", "Process value archive\\PDL_ZT_2"); SetPropWord(lpszPictureName, "Control2", "TrendColor", RGB(0,255,0)); SetPropChar(lpszPictureName, "Control2", "TrendTrendWindow", "myWindow"); SetPropChar(lpszPictureName, "Control2", "TrendTimeAxis", "myTimeAxis"); SetPropChar(lpszPictureName, "Control2", "TrendValueAxis", "myValueAxis"); //add new trend and assign properties SetPropChar(lpszPictureName, "Control2", "TrendAdd", "myTrend3"); SetPropWord(lpszPictureName, "Control2", "TrendProvider", 1); SetPropChar(lpszPictureName, "Control2", "TrendTagName", "Process value archive\\PDL_ZT_3"); SetPropWord(lpszPictureName, "Control2", "TrendColor", RGB(0,0,255)); SetPropChar(lpszPictureName, "Control2", "TrendTrendWindow", "myWindow"); SetPropChar(lpszPictureName, "Control2", "TrendTimeAxis", "myTimeAxis"); SetPropChar(lpszPictureName, "Control2", "TrendValueAxis", "myValueAxis"); I hope this will help.
