摘要： A cable includes a wiring assembly with a knuckle and wires bundled together. The cable also includes a connector assembly with a connector having connections for the wires, where the connections are arranged along a longitudinal axis. In some embodiments, the connector assembly captures an end of the wiring assembly, and the knuckle of the wiring assembly is pivotally connected to the connector assembly. In some embodiments, the cable includes circuitry configured to authenticate the cable to a device connected to the cable by the connector and/or to authenticate the device connected to the cable. A control system includes control elements and/or subsystems coupled with a backplane adjacent to one another and cables configured to connect to the control elements and/or subsystems. Wiring assemblies of the cables can articulate to be parallel to each respective connector. Further, each cable can authenticate the cables and/or the control elements or subsystems.

摘要： A secure industrial control system is disclosed herein. The industrial control system includes a plurality of industrial elements (e.g., modules, cables) which are provisioned during manufacture with their own unique security credentials. A key management entity of the secure industrial control system monitors and manages the security credentials of the industrial elements starting from the time they are manufactured up to and during their implementation within the industrial control system for promoting security of the industrial control system. An authentication process, based upon the security credentials, for authenticating the industrial elements being implemented in the industrial control system is performed for promoting security of the industrial control system. In one or more implementations, all industrial elements of the secure industrial control system are provisioned with the security credentials for providing security at multiple (e.g., all) levels of the system.

摘要： A programmable discrete input module is described. In one or more implementations, the programmable discrete input module comprises a pulse width modulation module configured to generate a pulse width modulated signal based upon an input signal and a pulse width demodulation module configured to generate a demodulated pulse width signal. An isolator is configured to isolate the pulse width modulation module and the pulse width demodulation module and to generate isolated modulated pulse width signal based upon the pulse width modulated signal for the pulse width demodulation module to generate the demodulated pulse width signal. The programmable discrete input module also includes a first comparator and a second comparator for comparing the demodulated pulse width signal with a respective programmable reference and a digital filter configured to filter a comparison signal output by the first comparator or the second comparator to generate a discrete input signal.

摘要： An electromagnetic connector is disclosed that is configured to form a first magnetic circuit portion comprising a first core member and a first coil disposed of the first core member. The electromagnetic connector is configured to mate with a second electromagnetic connector, where the second electromagnetic connector is configured to form a second magnetic circuit portion comprising a second core member and a second coil disposed of the second core member. The first core member and the second core member are configured to couple the first coil to the second coil with a magnetic circuit formed from the first magnetic circuit portion and the second magnetic circuit portion when the electromagnetic connector is mated with the second electromagnetic connector. The magnetic circuit is configured to induce a signal in the first coil when the second coil is energized.
