Parameter Description

Root Path

Data storage path.

Subfolder Settings

Click Add a subfolder to add up to five subfolders incrementally.

Naming rules: choose to name subfolders based on date, judgment result, and product identifier.

  • Date: current save date.

    • Date format: either YYYY-MM-DD or YYYYMMDD.

    • Validity: Subfolder retention period. Set to 7 days, 30 days, or no expiration.

  • Result: OK or NG. Input from an external Step (Bool).

  • Product identifier: can be entered manually or from an external Step (string data).

    • Input from an external Step: when this parameter is selected, the result of an external Step needs be input to this Step as the subfolder name. Only string data is allowed.

    • Product identifier: Enter manually the information as the product identifier.

  • Subfolder levels are based on the root path, not the system root directory.

  • Add at most one subfolder per category when naming by date or judgment result.

File Name Prefix
