Access File System via CODESYS

[ControlsFreak]

Has anyone used the SysDir and SysFile libraries to access files on the groov-EPIC via CODESYS?

I have a recipe tool that I wrote for another CODESYS based PLC that stores the recipes in a file. I could access a folder on that device by using this syntax for the folder: “\MyFolder\Recipes”.

I have created the folders and copied my files onto the device (from the IDE), but when I try to access the folder in code, I get an invalid handle.

Thanks!

Welcome to the forums!

This is a Linux file system permissions issue.
The user that Codesys is running as does not have permissions to the file system directory you are using.
Its the same issue here:

EPIC unsecured file access via Ignition Edge

I’m trying to use the relatively new file transfer capability with Ignition Edge and am running into permission issues for the unsecured files in the EPIC. Using scripts in Ignition, I’d like to download a still-image jpeg from a security camera to the EPIC. The library urllib and function urlRetrieve do that well on my Windows computer, but I can’t get it to work on the EPIC. When I try to save file to the EPIC unsecured directory ‘/home/dev/unsecured/’, I get ‘permission denied’ from the Opto…

Grab yourself a free shell license (if you have not done so already) from here:

Tweak your permissions and you should be up and running in short order.

Thanks @Beno! It was really just a matter of figuring out the file path and Shell access was the key there. I’m up and running now.
