Function Block FS_RMFILE

The Function Block FS_RMFILE deletes a file.

Warning: Files are deleted without warning.

The File System must have been initialized beforehand using FS_INIT. All operations occur asynchronously per configured storage medium.

Input DEV

Defines the device to which files are to be accessed. The device is used per project and can be managed in the context menu under Project ▸ External Storage.

Input PATH

Folder/Subfolder/File.txt

Output DONE

The output returns a pulse on success to perform the next operation. The pulse occurs when the process ends, even if an error has occurred.

Output ERROR

In case of an error, it returns a text with an error message. This is FALSE if no error has occurred. The state is stored for later use.

• The memory was not initialized.
• The login credentials are invalid.
• The remote server could not be reached.
• The storage medium does not exist.
• The specified path is invalid.
