  • Publication number: 20220075337
    Abstract: Various embodiments of the present technology generally relate to power topology discovery in industrial environments. More specifically, some embodiments relate to automatic power topology discovery for factories based on device data that is already recorded for other purposes. Systems and methods described herein may be used to generate an accurate electrical network topology by collecting power data from power devices that may provide real-time or recorded measurements, detecting power change events, and matching power change signatures over power events for the devices in order to calculate the likelihoods of possible topology assumptions. Power change event data is used to recursively update topology probabilities using the Bayesian formula until a system topology can be produced with satisfactory confidence.

  • Publication number: 20220066790
    Abstract: For device configuration and monitoring, a processor receives configuration settings from an electronic device via the electronic device interface. The processor converts the configuration settings to hardware settings for a target device. The processor communicates the hardware settings to the target device via a target device interface.

  • Patent number: 10747508
    Abstract: For function block framework generation, a method generates a function block framework for a hardware device. The function block framework includes function block framework source code and a function block framework description. The hardware device includes a logic engine and automation hardware. The function block framework presents a standard interface to a function block core executed by the logic engine. The method instantiates the function block framework and the function block core as an executable image for the hardware device. The method further configures the logic engine to execute the executable image using the function block framework description. The method executes the executable image with the logic engine.

  • Patent number: 10571495
    Abstract: A system includes a plurality of power monitors that, in operation, monitor parameters of power in an automation system at points between loads and/or power sources. Each of the power monitors includes sensing circuitry to sense the power parameters, peer-to-peer communications circuitry to communicate with other power monitors via peer-to-peer communication, network communications circuitry to communicate with automation devices via a network, and functional circuits to perform analysis of monitored power parameters in a cooperative manner based upon the power parameters monitored by the respective power monitor and power parameters monitored by other power monitors communicated via peer-to-peer communication.

  • Patent number: 9568514
    Abstract: An apparatus includes an upstream/downstream probability module that determines, for each measurement point in an electrical power system, an upstream/downstream probability. The apparatus includes a zone module that identifies a plurality of zones within the power system and an upstream/downstream module that identifies, for each measurement point and for each zone, if a power quality event in a zone is upstream or downstream of a measurement point. The apparatus includes a zone probability module that determines a zone probability for each zone by multiplying the upstream probability or the downstream probability for each measurement point. The zone probability is a probability that the event happened in a zone. The zone probability module uses the upstream probability of a measurement point when the zone is upstream of the measurement point and uses the downstream probability when the zone is downstream of the measurement point.
