Abstract
An apparatus for detecting faults of components monitored by a building management system (BMS), including an automatic fault detection (AFD) element that monitors, in real time, data samples generated by the BMS indicating operative states of the components, and that employs the data samples to determine if one or more of the components are faulty. The AFD element includes a run time modeling element and a virtual datapoint creating element. The run time modeling element employs the data samples as inputs to execute one or more fault algorithms retrieved from a system configuration model, and generates outputs to the one or more fault algorithms that indicate if the one or more of the components are faulty. The virtual datapoint creating element estimates one or more synthesized datapoints that may be required by the one or more fault algorithms during execution by the run time modeling element.
