Abstract: An environmental control system for a building intended for human occupancy in which the operating environment is controlled in response to any of a plurality of states of the building as represented by a state vector. A plurality of independently operating controllers contain stored sets of addressable control functions which are accessed by the state vector signal. The controllers produce operating point signals for apparatuses which affect operating environment parameters in accordance with the addressed control functions.

Abstract: The present invention relates to a control solution development environment coupled to a runtime environment constructed to insulate the control solution designer as well as the developed control applications from both the hardware and the operating system. This insulation frees the designer from having to deal with a tangle of control and operating system commands and considerations. The runtime environment manages the details of the process system resource and task allocation to implement the control strategies. Since the runtime environment insulates the developed control applications from changes in operating systems and hardware, applications developed to run in this environment are both reusable and portable. The runtime environment is scaleable, fault-tolerant, allows dynamic reconfiguration of the system, integration of diverse sensors and actuators and enables distributed control strategies.
