摘要： 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.

摘要： A time-stamping layer is provided for time-stamping of events detected in an industrial safety system. The technique implemented by the time-stamping layer uses autonomous device counters and simple arithmetic to label detected events (e.g., safety switching events) with accurate time-stamps without the need to synchronize clocks of the individual safety input devices and safety relay on the safety circuit. In some embodiments, the time-stamping technique is implemented in a single-wire safety system architecture that yields reliable safety device monitoring without the need for dual redundant signal channels.

摘要： A single-wire safety system architecture is provided that yields reliable safety device monitoring without the need for dual redundant signal channels. The safety system comprises a safety relay acting as a communications master device and one or more compatible safety devices connected in series with the safety relay via a single-wire communication circuit. The safety device farthest from the safety relay on the safety circuit modulates a safety signal with a recognizable pulse pattern that traverses the single-wire safety circuit to the safety relay via the intermediate safety devices. The safety relay maintains safety mode as long as the pulse pattern is received and recognized. The architecture allows bi-directional communication of initialization, configuration, and diagnostic messages over the single-wire safety channel, and can also allow safety devices to insert prognostic data into the safety signal in order to convey health information while the system is in normal operation mode.

摘要： 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.

摘要： A housing for an industrial sensor comprises integral U-shaped pockets configured to engage with attachment features of a complementary mounting bracket. The bracket comprises an overhang feature on a second end and a snap feature on an opposing first end. The housing can be mounted to the bracket by inserting a mounting boss formed within one of the U-shaped pockets underneath the overhang feature of the bracket, and pressing the housing against the bracket to cause the snap feature to engage with another mounting boss formed in the other U-shaped pocket. These mounting features allow the housing to be mounted easily and quickly without the use for additional tools. The housing can also be quickly removed from the bracket by pressing an extended tab near the snap feature to facilitate disengagement of the housing from the bracket.

摘要： A single-wire safety system is provided that yields reliable safety device monitoring without the need for dual redundant signal channels. The safety system comprises a safety relay acting as a communications master device and one or more safety devices connected in series with the safety relay via a single-wire communication circuit. A smart tap device is used to interface safety devices that are not compliant with the single-wire protocol to the single-wire channel. The safety device or smart tap device farthest from the safety relay on the safety circuit modulates a safety signal with a recognizable pulse pattern that traverses the single-wire safety circuit to the safety relay via the intermediate safety devices or smart taps. The safety relay maintains safety mode as long as the pulse pattern is received and recognized. The architecture allows bi-directional communication of initialization, configuration, and diagnostic messages over the single-wire safety channel.

摘要： A modular connector system allows a user to configure physical and functional aspects of a sensor or electrical connector assembly to suit the requirements of a particular installation or application. A header module houses an electrical component, such as a photo sensor, a proximity switch, a safety sensor, etc. A variety of field modules and adapter modules are provided that can be selectively added to the header module to accommodate a wide range of applications. These field and adaptor modules can include power modules, communication modules, or other types of signal processing modules. The housings and electronics of the header, field, and adapter modules are designed such that the field and adapter modules can be rotated relative to the header module to suit physical environment of the connector's location.
