Abstract: An arrangement in a building control system includes a plurality of field panel devices. Each field panel device is configured to receive control inputs and further configured to provide control outputs to at least one building control device. Each field panel device includes a data store, a communication circuit, and a processing circuit. The data store maintains a set of global data that is shared by all field panel devices. The communication circuit is operably connected to others of the plurality of field panel devices via a logical network. The processing circuit is operable to communicate changes of any of the set of global data to at least one other field panel device via the communication circuit.

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 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.
