Hi guys,

I'am building a block icon and faceplate with WinCC 14. From the block icon, i've a C script to call the faceplate, and set a TagPrefix.

Ths Script it's working fine, but an error appear in the Global Script Diagnostic Window.

I would like to clear it, but i don't know the source of the error.

Could anyone help me to understand the reasone?

Thanks

Regards.

Hi Murof,

Following the C scripts.

In my peoject, i've configured 6 Pictire Windows, in order to open in a dinamically way my faceplates. To do that i build the picutre window's name from Win0 till Win5, and i control it with a WinCC local variable.

In the mean time i''l have a look at your posted link.

Regards.

Duccio.

 This is the scritp

char* nomeOggetto=objectName;//Returns the cliked object's name, this is the calle dfaceplate's TagPrefix
char* tagPrefix = "";
char* screenControlName = "fpMotL";//Faceplate's name to be called.
char* screenWindowName = ""; //Picture Window's name
char* screenWindowTitle = "Motor Management";//Faceplate's header
char* objectHeader = "MotL";
char*nomePagina=screenName;
char*nomePropieta=propertyName;
char* author = "CA";
int n = GetTagWord("winAmount");


//*********************************************************************************************************************************
//                                                      Int To String
//*********************************************************************************************************************************
//Int To String conversion
//This will be usefull to build the picture window's name,
//in order to automatically rotate the called faceplate into the six configured picture windows.
int winInc=GetTagWord("winCount");
char TmpStr[64];
if (winInc<0 || winInc>n) winInc=0;//value must be between 0 and 6
sprintf (TmpStr, "%u", winInc);
//printf("\"%s\"\r\n",TmpStr);


//*********************************************************************************************************************************
//                                                 Picture Windows's settings
//*********************************************************************************************************************************

//screenWindowName is the Picture Window's name.
//This name, will be a dinamic name, and is = to win+TmpStr
screenWindowName=concat("win",TmpStr);


nomeOggetto++;//pointer increase to delete the unnecessary symbol
tagPrefix=nomeOggetto;//Set the tagPrefix to the called Picture window


//printf("nomePagina = %s\r\n", nomePagina);
//printf("nomeOggetto = %s\r\n", nomeOggetto);
//printf("tagPrefix = %s\r\n", tagPrefix);


MotrFp(screenWindowName,screenWindowTitle,screenControlName,tagPrefix,objectHeader,author,screenName);

winInc=winIndex(winInc,n);//once the faceplate has been opened, the control variable will be increased between 0 and 6.
SetTagByte("winCount", winInc);

 this is the called functions

 MotorFp

void MotrFp(char* screenWindowName, char* screenWindowTitle, char* screenControlName, char* tagPrefix, char* objectHeader, char* author, char* parentScreenName)
{

SetPropChar(parentScreenName, screenWindowName, "TagPrefix", tagPrefix);
SetPropChar(parentScreenName, screenWindowName, "CaptionText", screenWindowTitle);
SetPropChar(parentScreenName, screenWindowName, "ScreenName", screenControlName);
SetPropBOOL(parentScreenName, screenWindowName, "Visible", TRUE);
SetPropChar(parentScreenName, screenControlName, objectHeader, screenWindowTitle);
}

 WinIndex

int winIndex(int index, int n)
{
if (index>n || index<0)
index=0;

//Funzione per il controllo della variabile intera che concorre a generare il nome della picture windows dei pop-up
//Dopo aver aperto il popup, incremento la variabile
index++;

//Verifico che la variabile sia sempre tra 0 e 5.
//Quindi dopo l'apertura del win5, azzero la variabile.
if (index==n)
index=0;

return index;

}

Hi Murof,

I got the problem, but not the solution.

The problema coming from the Object property that is NULL, but Why? what should i set to remove the error?

Thanks.

Duccio.
