A Tulip Table that logs the history of activity of a machine. New rows are created by Machine Triggers and data within the most recent row can be manipulated from Machine Triggers and/or Triggers. Historical rows (i.e. all rows except the most recent) are not editable. A set of default columns within the table are pre-populated and not customizable by the user. The user can extend these defaults by adding custom Machine Activity Fields as needed. Custom fields available for a machine are part of the definition of a Machine Type.
