Function Block FS_RENAME

The Function Block FS_RENAME renames files or folders or moves them to another location.

Warning: Existing files are overwritten without a warning.

The file system must have been initialized beforehand using FS_INIT. All operations take place asynchronously per configured storage medium.

Input RENAME

A positive edge triggers the renaming or moving of data on the storage medium.

Input DEV

Defines the device from 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 SRC_PATH

Specifies the source path to the file or folder on the storage medium. The path corresponds to a Unix file path in UTF-8 format, if this is supported. The path is represented as follows:

Folder/Subfolder/File.txt

Input DEST_PATH

Specifies the destination path for the file or folder on the storage medium. The complete path name must be specified.

Output DONE

The output returns a pulse upon success to perform the next operation. The pulse occurs when the process is completed, 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.

Possible causes:

• The service of the storage medium was not started.
• The storage 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.
• Writing to the storage medium is not possible.
• No more storage space available on the storage or the storage is write-protected.
