Dear All,

I would like to save data in txt file for plotting by Matlab. Following code I am using but result is not that one I want I have shifted to right in each row:
PROGRAM PLC_PRG
VAR
hFile: DWORD;
szFilePath: STRING:= 'C:\ay.txt';
wNewLine: ARRAY[1..20] OF STRING;
(wNewLine:STRING;)
dwWritten:DWORD;
CloseFile: BOOL;
ay:STRING;
i: INT:= 1 ;
strString:STRING;
Lenght: INT;
SizeoFile: DINT;
END_VAR

hFile := SysFileOpen(szFilePath, 'a');

WHILE (i <> 30) DO

ay :=INT_TO_STRING(i);

dwWritten:= SysFileWrite(hFile, ADR(ay), SIZEOF(ay));
strString := CONCAT(ay, '$R$L');
i := i+1;

END_WHILE

Lenght := LEN(strString);
(Close the Opened File)
CloseFile := SysFileClose(hFile);
SizeoFile := SysFileGetSize(szFilePath);

Result in ay.txt file I am looking for:
1
2
3
4
5
6
...30
RESULT I GOT:

you write to file var ay which doesn't contain CRLF, write strString instead

Hi,

Thanks for your reply, How can perform CRLF in CodeSys . I solved the problem with "CONCAT" and "$R$N". And now I have problem how to save data in 2 columns in excel file. In such way that if I could plot each column.

put a comma in between the columns so it will be a CDF

and check your string length strstring:string(3);
