4. Exemplo de uma Função de Projeto e/ou uma Função
Standard
Controle de um motor:
Eventos/ mouse/ botão esq. mouse/ função em C...
BitSet ( 1, "MotorStatus", 2);
0
/*Bit 2 é setado na tag “MotorStatus”, para re-setar
o bit, use: BitSet ( 0, “MotorStatus”, 2)*/
Função definida no “Global Script”(Standard Functions):
void BitSet(BOOL OnOff, char* lpszWordtag, WORD wbitnumber)
{
WORD
int
winput = 0;
iscreen = 1;
// Cria as variáveis locais
winput = GetTagWord ( lpszWordtag ) ;
iscreen <<= ( wbitnumber );
if (OnOff == 0 ) {
winput = (WORD) ( winput & (~iscreen) );
}
else {
winput = (WORD) ( winput | iscreen );
}
SetTagWord ( lpszWordtag, winput);
}

5. Processamento em “Background” (Actions) com Global
Script
Operating hours.PAS
WORD HOUR, MINUTE;
BYTE Z_ON;
Z_ON = GetTagByte ("Z_On");
if (Z_ON) {
MINUTE = GetTagWord ("Minutes");
MINUTE = MINUTE + 1;
SetTagWord ("Minutes", MINUTE);
HOUR = MINUTE / 60;
SetTagWord ("operating hours", HOUR);
}
return(HOUR);
Nota: O “Global Script” deve estar ativado na lista de inicialização do WinCC

6. Exemplo com Funções a partir de DLLs
Contando com a Função DLL
Eventos/ Botão/ Mouse/ Press left/ C action...
#pragma
code("c:a_WinCC_Kurs_Prj_301_00ab_paslibrarydemo_dll.dll")
int CountingDll(int start, int end);
#pragma code()
int result, start, end, partial step;
partial step = GetTagDWord("partial step");
printf("rnrnoutput of 10 partial steps with DLL function ");
printf("to max. value: %d",partial step*10);
for (start=0;start<10;start++) {
end = start * partial step + partial step;
result = countingDll(start*partial step,end);
printf("rnReturn value DLL function: (%d) %d",start,result);
}
