Thank you i appreciate your answers.
i changed the type of deviceName to STRING but it still don’t working.
Did you change the value to the deviceName variable too ?
It’s normal FTP server root is on D:/ of you PLC. So in filezilla you see / as the root folder of the FTP server not the file system of the PLC.
yes like you said, i changed the value of the deviceName, and the code showing any errors so it works but the plc didn’t create the filder.
Use D: and check the errors return from the OpenFile FBK.
Then you should have info that the file didn’t exist
no i add FileCreation in my code and even i do this it still give me an error 2

but without any result.
Try set the FileDevice to F: for me the User partition is F: not D:
If you are on AS4.12 your can use USER_PATH instead of a drive letter
Thank You for your support.
The F:/ directory gives the previouse error 20708. and it dosn’t work at all.
USER_PATH instead of a drive letter. How i can use this ?
i do the same thing but it gives an error that the file doesn’t exist, 20708
Please check help of function blocks B&R Online Help
The FileCreate function block give you the file identifier. You don’t need to use FileOpen.
As your screenshot show you successfully create the file. Now you can read or write on it and Close it.
Important : If a file ident is create you need to close it with the FileClose FBK, even if a write or a read failed.
Please check the online help there is complete example for usage:
Hello guys.
well i wanna thank you for your help.
finally i created and wrote in the file successfully, that’s why i will shared with you my code like a solution and the config that you should do so as to do this task.
this is my code :
CASE step OF
4:
DirCreate_0.enable := TRUE;
DirCreate_0.pDevice := ADR(deviceName);
DirCreate_0.pName := ADR('/');
DirCreate_0();
IF DirCreate_0.status = 0 THEN
DirCreate_0.enable := FALSE;
step :=0;
ELSIF DirCreate_0.status = 65535 THEN
DirCreate_0.enable := FALSE;
step :=4;
END_IF
0: // Créer le fichier
fbOpen.enable := TRUE;
fbOpen.pDevice := ADR(deviceName);
fbOpen.pFile := ADR(fileName);
fbOpen.mode := 2; // Lecture/écriture (vérifie la valeur dans ta doc)
fbOpen();
IF fbOpen.status = 0 THEN
hFile := fbOpen.ident;
fbOpen.enable := FALSE;
step := 1; // Passer à l'écriture
ELSIF fbOpen.status = 65535 THEN // Fichier non trouvé
fbOpen.enable := FALSE;
step := 10; // Créer le fichier
ELSE
status := fbOpen.status;
step := -1; // Erreur fatale
END_IF
10: // Création du fichier
fbCreate.enable := TRUE;
fbCreate.pDevice := ADR(deviceName);
fbCreate.pFile := ADR(fileName);
fbCreate();
IF fbCreate.status = 0 THEN
fbCreate.enable := FALSE;
step := 0; // Réessayer l'ouverture
ELSIF fbCreate.status = 20705 THEN
step := 0;
ELSE
step := -1; // Erreur de création
END_IF
1: // Écriture
fbWrite.enable := TRUE;
fbWrite.ident := hFile;
fbWrite.pSrc := ADR(writeBuffer);
fbWrite.len := SIZEOF(writeBuffer);
fbWrite.offset := 0;
fbWrite();
IF fbWrite.status = 0 THEN
fbWrite.enable := FALSE;
step := 2;
ELSIF fbWrite.status = 65535 THEN
fbOpen.enable := FALSE;
step := 0;
END_IF
2: // Fermer
fbClose.enable := TRUE;
fbClose.ident := hFile;
fbClose();
IF fbClose.status = 0 THEN
fbClose.enable := FALSE;
step := 3;
ELSIF fbClose.status <> 65535 THEN
status := fbClose.status;
step := -1;
END_IF
-1: // Erreur
IF fbCreate.status = 65535 THEN
fbCreate.enable := FALSE;
step := 10; // Réessayer l'ouverture
END_IF
IF fbWrite.status = 65535 THEN
fbWrite.enable := FALSE;
step := 1;
END_IF
// status contient l’erreur
3: // Terminé avec succès
;
END_CASE
and this is the confi that you should do :
fbOreate : FileOpen;
fbWrite : FileWrite;
fbClose : FileClose;
fbOpen : FileOpen;
hFile : UDINT := 0;
deviceName : STRING[80] :=‘HD’;
fileName : STRING[255] := ‘data.txt’;
writeBuffer : STRING[255] := ‘yacine’;
bytesWritten : DINT := 0;
step : INT := 0;
status : DINT := 0;
fbCreate: FileCreate;
DirCreate_0 : DirCreate;
But you should know that the PV memory of the PLC is limited and those functions didn’t work in cycle.
THANK YOU ALL 
Happy that our BRCommunity helped you find the solution 
Just a heads up to your working code: One shouldnot check for “0” and “65535” but ERR_OK and ERR_FUB_BUSY.
Please also note that your fb write code (step 1) does miss error handling and returning to step 0 in case of BUSY (65535) is surely wrong as well.
Anyway, good luck
