Abstract:
A virtual fieldbus device module is a software or firmware module that enables an otherwise ordinary fieldbus device to become a complex fieldbus device, capable of registering and maintaining multiple fieldbus network addresses for one or more “virtual” fieldbus devices. Each virtual fieldbus device has one or more sensor inputs and appears to the fieldbus network as an individual physical fieldbus device, despite the complex fieldbus device only having one physical connection to the fieldbus network. The virtual fieldbus device module may be incorporated into a device's firmware or may be included in a memory plug-in capable of being removed. The communication packet processing of a complex fieldbus device running the virtual fieldbus device module includes receiving a communication packet over the fieldbus network, determining whether the address associated with the packet matches any of the addresses registered by the complex fieldbus device, and processing any packets that match.
Abstract:
A method for detecting an event and/or behavior of interest based on monitoring data and selectively storing portions of the monitoring data associated with the event and/or behavior of interest. Preferably, the method includes defining a hierarchy of event and/or behavior types so that the storing of a first behavior/event type is preferred over a second behavior/event type, especially when storing capacity is scarce. A data management apparatus including a logic device and a long-term storage memory apparatus, the logic device for detecting an event and/or behavior of interest based on monitoring data and selectively storing portions of the monitoring data associated with the event and/or behavior of interest on the long-term memory storage apparatus.

Abstract:
The invention provides a computerized method and apparatus which enables a user, even one who has little or no predictive maintenance skills, to establish a predictive maintenance database that defines information needed to monitor equipment in accordance with a predictive maintenance plan. The type of equipment components to be monitored and associated physical characteristics of the components are input to a computer as an equipment configuration, which may include one or more interconnected components. The computer includes a knowledge base that defines relationships between monitoring practices, component types, and physical characteristic information for component types. A predictive maintenance database is constructed for the components using the inference engine operating on the knowledge base, the selected component type, and the selected physical characteristic information. Multiple measurement technologies may be specified for each component. Preferably, for each measurement technology specified, the predictive maintenance database includes measurement points, an analysis parameter set, and an alarm limit set. Equipment configurations may be defined by the user, or they may be stored in a configuration/component warehouse with little or no configuration definition required of the user.
