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:

An improved distribution system for use in supervising and controlling temperature and other environmental conditioning equipment of a building or the like is disclosed. The distribution system is used in conjunction with a host or central computer. The distribution system includes one or more distribution panels which communicate with the host computer as well as with various control point apparatus that gather temperature, humidity, and other types of values, or gather status information regarding electrical switch states and the like. Other types of control point apparatus control electric motor starters, motors, or other control equipment for controlling environmental conditions or general energy use. The distribution panels have various function means therein which are capable of receiving digital input signals, providing digital output signals to control point apparatus, receiving frequency analog input signals, pneumatic analog input and output signals, and the like. The function means have the capability of being uniquely characterized with respect to the type of operation that is to be performed and certain function means can also be characterized to selectively provide change of value reporting to the central computer as well as significant change of value reporting.
