Abstract: A method includes sending a first safety instruction to a machine in response to, within an entry window of time, receiving an open alert that a movable barrier is in an open state, where the movable barrier is at an entry point of an enclosure protecting personnel from the machine, receiving tag information of a person from a reader at the movable barrier, and confirming that the tag information belongs to a person authorized to enter the enclosure. The method includes sending a second safety instruction to the machine in response to, within the entry window of time, receiving the open alert, and without receiving tag information or confirming that the tag information belongs to a person authorized to enter the enclosure. The first and second safety instructions are different and the first safety instruction is less restrictive than the second safety instruction in terms of actions to prevent injury.

Abstract: A component for light curtain alignment includes a light intensity receiver that receives a plurality of light intensity signals from beam receivers of a receiver unit of a light curtain. The light curtain includes a transmitter unit with beam transmitters arranged linearly on the transmitter unit. The light curtain includes the receiver unit with the plurality of beam receivers arranged linearly. Each beam receiver is configured to receive light from a corresponding beam transmitter. The component includes a light intensity transmitter configured to transmit, from the light curtain, the plurality of light intensity signals received by the light intensity receiver, where each light intensity signal is from one or more beam receivers, and a trip transmitter that transmits a trip signal in response to determining that a light intensity signal from a beam receiver of the plurality of beam receivers is below a trip threshold.

Abstract: A method for monitoring machine operation for various machine speed and loads includes measuring vibration information at a sensor associated with a machine and an associated machine speed. The machine is a rotating machine. The method includes performing an operational frequency analysis of the vibration information and comparing results from the operational frequency analysis with a vibration signature for the machine. The vibration signature is for a machine speed that matches the machine speed of the measured vibration information. The vibration signature is one of several vibration signatures for the machine where each is for a different machine speed. The method includes identifying a potential failure mode based on a frequency range where the frequency analysis of the measured vibration information exceeds, by a threshold amount, the vibration signature of the plurality of vibration signatures that matches the machine speed, and transmitting an alert comprising the identified potential failure mode.

Abstract: A component includes a housing mounted at an entry point of an enclosure protecting a machine. The component includes a first RFID sensor, in the housing, that reads a first RFID tag in close proximity to the first RFID sensor indicating a closed status of a movable barrier of the enclosure at the entry point. Opening of the movable barrier allows entry to the enclosure. The component includes a second RFID sensor, in the housing, that reads a second RFID tag of an authorized person. The component includes a barrier access module that sends an open alert that the movable barrier is in an open state in response to the first RFID sensor not being close enough to read the first RFID tag, and an identification module that sends tag information unique to a person from the second RFID tag.

Abstract: An industrial Single Pair Ethernet (SPE) system and method for connecting devices within an industrial automation system is provided. The industrial SPE system comprises a trunkline formed by a series of trunk cables, where each trunk cable includes a power pair and an SPE pair, and one or more taps connected between the trunk cables of the trunkline. The industrial SPE system further comprises a drop line connected to each of the one or more taps, and a device connected to each of one or more taps via the drop lines. The device is an actuator or a sensor, and at least one of the device and the one or more taps includes a dual-port SPE switch.

Abstract: A method for predicting end-of-life for a component includes determining a baseline lifetime model for a component connected to a machine functional safety system. The component is part of a system with physical devices. The method includes monitoring environmental conditions and usage conditions of the component and modifying the baseline lifetime model based on the monitored environmental and usage conditions to produce a modified lifetime model for the component. The method includes tracking a lifetime progress of the component with respect to the modified lifetime model and sending an alert in response to lifetime progress of the component reaching a lifetime threshold associated with the modified lifetime model.
