Abstract: Embodiments of this present disclosure may include an industrial control system that uses a daisy chain communication network to couple point-to-point sensors (P2P sensors) for communication of data between respective P2P sensors and a controller. Each P2P sensor may couple to the daisy chain communication network via accessing circuitry. The accessing circuitry may include switching circuitry and flip-flop circuitry to control when each P2P sensors may communicate with the controller via the daisy chain communication network.

Abstract: A method may include receiving, via a processor, a request to enable movement of a rotor. The method may involve sending a first signal to a mechanical relay system in response to receiving the request, such that the second signal may cause a mechanical relay to close. The mechanical relay system is configured to couple a first conductor to an EM brake. The method may also include sending a second signal to a solid-state relay system after sending the first signal to the mechanical relay system, such that the second signal may cause a solid-state relay to close. The solid-state relay system may couple a second conductor to the EM brake, such that the EM brake may open after receiving power via the first conductor and the second conductor.

Abstract: Control circuitry of a motor drive provides commands for operation of power circuitry in cooperation with peripheral circuits and devices, such as converters, inverters, feedback precharge circuits, feedback devices, interfaces, and so forth. The communications with the devices is handled by fiber optic communications circuitry that implements a flexible scheme of dynamic interval communication depending upon the capabilities and design of the peripheral circuit or device. The communication may be in accordance with a plurality of predetermined schemes, each having different data transfer rates, data allocations, and so forth. The schemes may each set communications protocols (e.g., timing) over a high speed interface between the fiber optic communications circuitry on one side and over fiber optic cables to the peripherals on another side.

Abstract: A tamper detection apparatus includes a switch and a tamper detection circuit with a non-volatile memory in an industrial product enclosure. In response to the switch detecting a door or panel of an industrial product enclosure being open when an electronic component or system in the enclosure is unpowered, the tamper detection circuit stores a tamper event code in the non-volatile memory. After the electronic component or system is powered, a system processor obtains the tamper event code from the tamper detection circuit and refrains from operating a machine or process pending reset of the industrial product by a user.

Abstract: Techniques include systems and methods of synchronizing multiple parallel inverters in a power converter system. In one embodiment, control circuitry is connected to a power layer interface circuitry at each of the parallel inverters, via an optical fiber interface. The system is synchronized by transmitting a synchronizing pulse to each of the inverters. Depending on the operational mode of the system, different data exchanges may occur in response to the pulse. In an off mode, power up and power down data may be exchanged between the control circuitry and the inverters. In an initiating mode, identification data may be transmitted from the inverters to the control circuitry. In an active mode, control data may be sent from the control circuitry to the inverters. In some embodiments, the inverters also transmit feedback data and/or acknowledgement signals to the control circuitry. Power layer circuitry of the inverter adjusts a local clock based upon sampled data from the control circuitry to maintain synchronicity of the inverters between synchronization pulses.

Abstract: Control circuitry of a motor drive provides commands for operation of power structure circuitry in cooperation with peripheral circuits and devices, such as converters, inverters, feedback precharge circuits, feedback devices, interfaces, and so forth. The communications with the devices is handled by power stage circuitry configured for the caliber system. The communications between the control circuitry and the power stage circuitry is handled by a high speed interface with multiple protocols. A first of these protocols may be based on a low voltage differential signal scheme, and another on a non-differential signal scheme, such as a negative bus reference scheme. The particular protocol selected may be based on detection of a voltage of a connector pin, and the selection and implementation may be fully automated.
