WINCC几个常用C语言编程

1、WINCC几个常用 C 语言编程全局脚本编程（按钮连续增减）说明： 1、建立全局脚本函数2、建立全局动作C 脚本3、在启动画面的打开画面中调用全局脚本函数4、在计算机的启动选项中选中全局脚本全局脚本函数 InitAction()extern char tagname30 = ;extern SHORT count = 0;extern FLOAT low = 0;extern FLOAT high = 0;extern FLOAT step = 0;void InitAction()按钮左键按下连续增加extern char tagname30;extern SHORT count;exter

2、n FLOAT low;extern FLOAT high;extern FLOAT step;strcpy(tagname,S32i_varia_but_04);count = 1;low = 0;high =1400;step =0.5;按钮左键按下连续减少extern char tagname30;extern SHORT count;extern FLOAT low;extern FLOAT high;extern FLOAT step;strcpy(tagname,S32i_varia_but_04);count = 2;low = 0;high =1400;step =0.5;按钮

3、左键松开停止增减extern SHORT count;count=0;全局动作 C 脚本（ counter.pas）#include apdefap.hint gscAction( void )extern char tagname30;extern SHORT count;extern FLOATlow;extern FLOAThigh;extern FLOATstep;FLOAT value;if (count=1)|(count=2) /get current valuevalue = GetTagFloat (tagname);if (count=1)/incvalue = value

4、+step;if (valuehigh) (value=high); /high limit/ifif (count=2)/decvalue = value-step;if (value1300) (value=1400);/check limitelse value=value+100;/inc valueSetTagFloat(S32i_varia_but_00,value); /set new value2、调用函数方式实现（ incdecvalue）：FLOAT value;value=GetTagFloat (S32i_varia_but_04);IncDecValue(&value

5、,0,1400,100,1);SetTagFloat (S32i_varia_but_04,value);项目函数（ incdecvalue）void IncDecValue(FLOAT *value,FLOATlow,FLOAThigh,FLOATstep,DWORD a)FLOAT v;v=*value; /get current value switch (a)case0: if (v(high-step)(v=high);/high limitelse v=v+step;/increment/case 1break;/switch*value=v; /return项目函数（ incdecvalue）文件：C 脚本编程 （按钮切换开关）：#include apdefap.hvoid OnLButtonDown( char* lpszPictureName, char* lpszObjectName, char* lpszPropertyName, UINT nFlags, int x, int y)BOOL state;/fliptags
