Saving a file to USB stick

Thanks for your tips, I found the problem!

I was using uppercase letters (like: /Media/USB0 )

When I tried lowercase text the problem was fixed.

Hello,

Do you get any error code?

I've done a project on a Berghof Dialog Controller where I saved to a USB-memory.

The line:

dwFileNumber:=SysFileOpen(sFileName,'w');

where sFileName was /media/usb0/filename.csv worked fine for me. It could be possible that the path to the file had a ending /

If you telnet to the device can you access /media/usb0 then?

Another tip is to use something like

xUSBPlugged:=INT_TO_BOOL(BGH_USB_GETPLUGSTATUS(0));

to make sure that the USB-key is plugged in. The function is available in the BghSysInfo_Vxx.lib library (xx=the version number).

Hi all,

Here's another programming question. I am using a linux based PLC (Berghof) and I want to save a file to an attached USB stick.

I can save a file to the program directory ( /flash/plc/applications/ ) but I need to save the file to /media/usb0/

How can I change the location of the file?

This does not work:

StLogFile := '/media/usb0/LogFile.txt'

SysFileOpen(StLogFile, 'w');

Thanks!
