摘要： 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 changes and/or modifications (events) to be made at the field panel to various objects or control points of the field panel, such as the point database, control programs, configurations and other data. A log of the changes made at the control panel is maintained, compiled and/or stored locally (i.e. at the field control panel level). The local log maintains the changes as events. The local log identifies data regarding the change itself, who made the change and when the change was made (identification data). The local log can be viewed locally or uploaded to a workstation where it can be stored, viewed and combined with a system wide log.
