EPIC CODESYS read csv file

I’m trying to read a csv file in EPIC HDD with CODESYS.
csv file location is /files/scanned-data.csv.
I use CSVReader Unit CFC of CSV_Util_SL.

I get an INVALID_HANDLE error when I run this

I can read this file in softPLC on PC.

Do you know the reason?

・CODESYS is running with administrator privileges.
・File permissions changed↓

Even with Administrator privileges Codesys only has access to the /home/dev/unsecured file location on the EPIC via.

You can access the above file location in Codesys using /home/codesys/unsecured as reference.

I can read /home/codesys/unsecured/file.
