Hi guys,

I didn't found the answer of my question in the forum so I decided to create a new topic.

My question is : How can I get the alarm text from an alarm ?

I work on WinCC RT Pro V15, and I try to get the number, the time and the text of an alarm. I already managed to get the number and the time, but I can't get the text. I use some printf and apdiag to see my outputs. Here is my actual code in the attached picture. In this code, on line 17, there is a missing instruction that I didn't found. I use the MSG_RTDATA_STRUCT.

I hope my explanations are clear, I stay for more explanations if needed.

Thank you for your time and your help.

Thanks and regards

Leo

Hi LeoH,

Maybe the structure definition of MSG_RTDATA_STRUCT helps you.
(you will find it in the WinCC Scripting manual)

typedef struct {

DWORD dwMsgState;
DWORD dwMsgNr;
SYSTEMTIME stMsgTime;
DWORD dwTimeDiff;
DWORD dwCounter;
DWORD dwFlags;
WORD wPValueUsed;
WORD wTextValueUsed;
double dPValue[MSG_MAX_PVALUE];
MSG_TEXTVAL_STRUCT mtTextValue[MSG_MAX_PVALUE];    (maybe its this one?)

}
MSG_RTDATA_STRUCT;

Hi Phi,

I tried it but it doesn't work, I have no result on my text outputs. Do you have another idea or another solution ?

You can see my code and my output window from apdiag in the zip file attached.

Thanks and regards

Hi Kal.A,

I tried to understand the similar thread that you gave me but I'm sorry I don't understand how textlists can help me to get the text of my alarm. 

Can someone help me to understand this point ? 

Thanks and regards

Leo.

P.S : The fact is that I didn't get the alarm text in a tag yet, that's my main problem.

Hi all,

Thanks a lot for your help I found the solution of my problem. I used this 3 lines in my C-Script and it works : 

If you need help or want more details about my script, just relaunch this topic 

Thanks and regards,

Leo.

Hi Leo,

Is there any way you can post the entire script?  Just so I can see your variable declarations and such.

This is EXACTLY what I've been looking for!

Thank you!

I share my funtion to obtain the text of an alarma .

The first return the TextID of the alarm and the second part return de text of TextID

 

MSG_RTDATA_STRUCT mRT;
MSG_CSDATA_STRUCT DatMsg;
CMN_ERRORA  pError;


BOOL bOK;
WORD wTextBlock=0;
DWORD dwTextNr ;
MSG_TEXT_STRUCT scMsgText;
CMN_ERROR scError;

//1º Return TextID of the alarm
DatMsg.dwMsgNr=101;
bOK=MSRTGetMsgCSData(100, &DatMsg , &pError);
dwTextNr =DatMsg.dwTextID[0];

//2º Return the Text of TextID

bOK = MSRTGetMsgText(wTextBlock, dwTextNr, &scMsgText, &scError );

return ("#I101: MSRTGetMsgText() - szText=\"%s\"\r\n", scMsgText.szText);
