Abstract: Systems and methods are provided. In one embodiment, a system comprises an electronic device configured to be used in an industrial control system. The electronic device includes a processor and a memory. The electronic device additionally includes a backwards compatible memory map stored in the memory, wherein the electronic device is configured to provide for a backwards compatibility mode of operations by applying the backwards compatible memory map and at least one memory map setpoint, wherein the backwards compatibility mode of operations provides for communications with an external device, and wherein the at least one memory map setpoint is included in an older version of the electronic device.

Abstract: The method includes measuring an operating parameter comprising at least one of a phasor current and phasor voltage of an electrical machine. The method further includes determining a diagnostic parameter indicative of a fault of the electrical machine based on the measured operating parameter. The method also includes estimating end of life of the electrical machine based on the diagnostic parameter using an error minimization method.

Abstract: A sensor to simultaneously detect light and acoustic waves is presented. The sensor includes one or more optical fibers and a diaphragm disposed near one end of at least one of the one or more optical fibers. The diaphragm is configured to vibrate upon incidence of acoustic waves from an arc flash and reflect a light beam into at least the one of the one or more of the optical fibers. A semi-transparent region is disposed around the one or more optical fibers to diffuse light originating from the arc flash into at least one of the one or more optical fibers.

Abstract: Disclosed herein relates to an enclosure-to-rail retaining system. The system includes, a rail that is fastenable to a structure, and an enclosure that is receptive of the rail. The enclosure has a slot therein that intersects a channel therein and is slidably engagable by a clip such that a portion of the clip can extend into the channel to thereby narrow a portion of the channel to a dimension less than a width of the rail.
