Hello, 

I am new to CXA_FileAsync with FB IL_FileWriteAsync for datalogging, are there any function block or possible to automatically transfer the data logged csv files from ctrlX to my PC every hour?

Moves to own topic from this one.

There are several ways to do so. First I like to mention that the CXA_SocketComm library also includes FTP and TFTP protocol to send files to a server e.g. your PC.

Hello CodeShepherd, 

Thank you for your reply!

I am new to CXA_SocketComm and FTP are there any examples to use the FTP IL_FTPGetAsync function block?

Hi,

Here is asimple demo code, maybe helpfull for you.

Declaration:

 

PROGRAM IL_FTPPut_Test
VAR
	fbFTPPut : IL_FTPPutAsync;
	fbFTPPutFile : IL_FTPPutFileAsync;
	
	filebuf: STRING(5000) := 'asdasd$R$N12312312$R$Npoipoi$R$N';
	sendlen: UDINT;
	
	itestcase: INT;
END_VAR

 

Implementation:

 

fbFTPPut();
fbFTPPutFile();

CASE itestcase OF
1: // put string
	fbFTPPut.Address := '192.168.1.101';
	fbFTPPut.Login := 'MyPcUserName';
	fbFTPPut.Password := '';
	fbFTPPut.RemoteFile := 'ftpsavefile'; // existing file
	fbFTPPut.ValueAdr := ADR(filebuf);
	fbFTPPut.NoOfBytes := IL_LEN(adr(filebuf));
	sendlen := fbFTPPut.NoOfSendBytes;	
	fbFTPPut.Execute := TRUE;

	IF fbFTPPut.Done THEN
		fbFTPPut.Execute := FALSE;
		itestcase := 0;
	END_IF
	
2: // put fie 
	fbFTPPutFile.Address := '192.168.1.101';
	fbFTPPutFile.Login := 'MyPcUserName';
	fbFTPPutFile.Password := '';
	fbFTPPutFile.RemoteFile := 'ftpcoty.scope'; //300kB
	fbFTPPutFile.LocalFile := ADR('_cnc/xy_2.scope');
	sendlen := fbFTPPutFile.NoOfSendBytes;	
	fbFTPPutFile.Execute := TRUE;

	IF fbFTPPutFile.Done THEN
		fbFTPPutFile.Execute := FALSE;
		itestcase := 0;
	END_IF

END_CASE

 

 

Hi,

I tried executing the above sample in my machine, the case1 just produced a file on my ftpserver with the given name & buffer data were successfully written to the file.

But the case2: did not retrive the file from my PLC to PC and it resulted the error codes as below

Error ID: RESOURCE_ERROR

Additional1: 16#0A0F0102
Additional2: 16#0C231010

same server successfully accessed by case1, but did not by case2 & could not find the description for the error codes shown here

the localfile was present in the ctrlX, pic as below
