Hello everyone,
When writing to the file whose code and configuration settings I have shared below, I encounter error code 20798 during the FileOpen function. Despite all my attempts, I have not been able to resolve this error.
My goal in using this file structure is to permanently store the values I need to write in my system. I would greatly appreciate any assistance you can provide on this matter.
Thank you.
