40304 File access error

TOBOR

When attempting to backup to the controller or through Robotstudio we are getting the below errors. Any ideas what causes this?

Robot: IRB 1600 Flexarc
Robotware: 6.06.00

Are you running short of storage space of SD card?  (the controller's)

TOBOR

Hi Lemster, not running short on space. We found this issue on more than one robot controller, so we are now investigating recent code added to these particular machines. 

lemster68

This is a really off chance here, but did you modify the system parameters to include files or folders not normally included in a backup?  I tried that a few years back, and found that it did not work.  May have even been the same error, if not, similar.

TOBOR

Thanks! Actually, that is exactly what we did. We created .txt file to write 3 lines of text every time a tool check was completed. This is simply to time stamp the process so we can quickly check when it was last done. 
Upon digging a little deeper into this it looks like there is another event message 41679 being triggered, buried in other alarms... See below snippets and the code in bold we will try and add.  

Open "HOME:"\File:="R1_BE_ToolCheck.txt",R1_BE_ToolCheck\Write;
Waittime 0.5;
Write R1_BE_ToolCheck,"R1 Bullseye last checked:";
Write R1_BE_ToolCheck,R1_BE_ToolCheck_date;
Write R1_BE_ToolCheck,R1_BE_ToolCheck_time;
close R1_BE_ToolCheck;
Waittime 0.5;

It is recommended to use the Close instruction before the Open.

But if you write it to the HOME directory it ought to be included in the backup.  As such, it would not be necessary to add the parameter to include that file.

TOBOR

Thanks, so close before and after like the below?

close R1_BE_ToolCheck;
Waittime 0.5;
Open "HOME:"\File:="R1_BE_ToolCheck.txt",R1_BE_ToolCheck\Write;
Waittime 0.5;
Write R1_BE_ToolCheck,"R1 Bullseye last checked:";
Write R1_BE_ToolCheck,R1_BE_ToolCheck_date;
Write R1_BE_ToolCheck,R1_BE_ToolCheck_time;
close R1_BE_ToolCheck;
Waittime 0.5;

It is in the HOME directory so maybe it is the Close issue.

lemster68

Uh, maybe if there is still an open com device active to that file.  But yes, Make sure it is closed before opening and close when you are finished writing.  We will see, won't we?
