经验证，个人认为这个脚本最好用/C脚本

#include "apdefap.h"
void OnLButtonDown(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName, UINT nFlags, int x, int y)
{
int j;
DWORD dwHelp1,dwHelp2;
j=MessageBox(NULL,"您确定要启动吗？","注意!",MB_OKCANCEL|MB_ICONEXCLAMATION|MB_SETFOREGROUND|MB_SYSTEMMODAL);
if (j==1)
{
   SetTagBit("ZCF-Start-HD",1);
  }
// WINCC:TAGNAME_SECTION_START
// syntax: #define TagNameInAction "DMTagName"
// next TagID : 1
// WINCC:TAGNAME_SECTION_END

// WINCC:PICNAME_SECTION_START
// syntax: #define PicNameInAction "PictureName"
// next PicID : 1
// WINCC:PICNAME_SECTION_END

}
然后在释放左键中组态C语言，复制下列代码，将“ZCF-Start-HD”更换为你要改变的变量即可
#include "apdefap.h"
void OnLButtonUp(char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName, UINT nFlags, int x, int y)
{
SetTagBit("ZCF-Start-HD",0);// WINCC:TAGNAME_SECTION_START
// syntax: #define TagNameInAction "DMTagName"
// next TagID : 1
// WINCC:TAGNAME_SECTION_END

// WINCC:PICNAME_SECTION_START
// syntax: #define PicNameInAction "PictureName"
// next PicID : 1
// WINCC:PICNAME_SECTION_END

}
