WINCC几个常用C语言编程.doc

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 chartagname30 = ;externSHORT count = 0;externFLOAT low = 0;externFLOAT high = 0;externFLOAT step = 0;voidInitAction()按钮左键按下连续增加extern chartagname30;externSHORT count;externFLOAT low;externFLOAT high;externFLOAT 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 chartagname30;externSHORT count;externFLOAT low;externFLOAT high;externFLOAT step;strcpy(tagname,S32i_varia_but_04);count = 2;low = 0;high =1400;step =0.5;按钮左键松开停止增减externSHORT count;count=0;全局动作C脚本（counter.pas）#includeapdefap.hintgscAction( void )extern chartagname30;externSHORT count;externFLOAT low;externFLOAT high;externFLOAT step;FLOAT value;if(count=1)|(count=2) /get current value value = GetTagFloat (tagname);if(count=1) /inc value = value+step;if(valuehigh) (value=high); /high limit /ifif(count=2) /dec value = value-step;if(value1300) (value=1400); /check limitelsevalue=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,0,1400,100,1);SetTagFloat (S32i_varia_but_04,value);项目函数（incdecvalue）voidIncDecValue(FLOAT *value,FLOAT low,FLOAT high,FLOAT step,DWORD a)FLOAT v;v=*value; /get current valueswitch(a)case0: if(v(high-step) (v=high); /high limit elsev=v+step; /increment /case 1 break; /switch*value=v; /return项目函数（incdecvalue）文件：C脚本编程（按钮切换开关）：#include apdefap.hvoidOnLButtonDown(char* lpszPictureName,char* lpszObjectName,char* lpszPropertyName,UINTnFlags,intx,inty)BOOL state; /flip tagsta
