By using the CAA FILE library (FB FILE.Open) (raspberry pi, codesys 3.5.19.0) I always get the error FILE_OPERATION_DENIED
The file exist, it has r/w/x access and path is correct...
Some idea to fix it?

due security reason files could only be accessed in /var/opt/codesys/PlcLogic directory

Hi @eschwellinger Is this new with SP19? Or Hardware based?

/var/opt/codesys/PlcLogic not work here, again FILE_OPERATION_DENIED. May I simply moved my files in /var/opt/codesys/PlcLogic or need some particular settings?

I have code written since version 3.5.16 to access the USB drive, how can I do that now the file access has been taken away?

I have tried adding a sybolic link to the usb drive in the following directories:
/var/opt/codesys/PlcLogic/
/var/opt/CODESYS/PlcLogic/
/opt/CODESYS/PlcLogic/

I still recieve a "FILE_OPERATION_DENIED" response when accessing the USB drive.

Hello everyone,
I am using SP19 patch 2 on a Kunbus device with runtime package 4.9.0.0. I am having the same problem as mentioned above. With the FB File.open I get the FILE_OPERATION_DENIED error. I have also tried the path /var/opt/codesys/PlcLogic. Any advice?
Chris

in your project, to access /var/opt/codesys/PlcLogic/my.file, use the string 'my.file' or '$$PlcLogic$$/my.file'
