Use File Name / Dynamic File name

Choose one of these radio buttons to determine where the file's name comes from:

Use File Name: Enter a static filename in the adjacent box.
Dynamic File Name: Select an application signal in the setup that contains the name of the file. This allows you to change the name of the file on the fly by using Set Value or other commands to adjust the name stored in that application signal.

Overwrite File if it exists

When selected, existing files are overwritten rather than creating new ones, to prevent filling the data directory with many log files.

Make logged data persistent

When selected, written data persists in storage.
