# Appendix

## Output file

Output CSV files are named according to two factors: file creation timestamp and N3uron node name. The following example is a generated file name: “1523462885954-main.csv”

Upon start-up, the values of all tags matching the specified filters will be saved, meaning that every subsequent event or virtual sample (according to the Force sample) setting will also be saved.

The generated files contain the following columns:

- **Data type:** B (Boolean), N (Number) or S (String).
- **Tag path****:** The tag’s full path, including prefix and specified separator.
- **Timestamp****:** In ISO 8601 format
- **Tag value**
- **OPC quality**

The following CSV file is an example of a file created using UFL Exporter.
