ABSTRACT:
A building control system, such as an HVAC system, has a field unit incorporating a control panel (a field panel) with a local user interface allowing user selected parameters for collecting trend information when the system detects a change of value for a point in the system or a timed instruction in the memory of the field panel to begin collecting trend data for a point. The resulting trend data collected by the field panel can be uploaded to a workstation in the building control system, where the trend data can be formatted into a report, and then digitally authenticated.
