1. A method of operating a building control system, the method comprising the steps of:
- receiving user generated parameters for collecting trend data at a field panel of the building control system, wherein the user generated parameters for collecting trend data at a field panel of the building control system comprise parameter for instructing the field panel when to begin collecting trending data after a predetermined trend event has occurred and a parameter for instructing the field panel when to stop collecting trending data after said predetermined trend event has occurredstoring trended data collected by said field panel regarding said user generated parameters at the field panel; and
transmitting the stored trended data regarding the user generated parameters at the field panel to a workstation.

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.
