    摘要: In a system and method for operating, at a near location, a remote safety-critical device, the system includes a first operating input device operated at the near location, providing a first barrier control signal; and a second operating input device to be operated at the near location, providing a second barrier control signal. The first barrier control signal is communicatively connected to a near end of a first secure communication tunnel, and the second barrier control signal is communicatively connected to a near end of a second secure communication tunnel, both through the non-secure communication network. Far ends of the first and second secure communication tunnels are communicatively connected to activating inputs of first and second barrier circuits, respectively. The first and second barrier circuits enable operation of the safety-critical device when both are activated.

    摘要: A system and method for operating, at a near location, a safety-critical device located at a far location. The system includes a first operating input device to be operated at the near location, providing a first barrier control signal; and a second operating input device to be operated at the near location, providing a second barrier control signal. The first barrier control signal is communicatively connected to a near end of a first secure communication tunnel through the non-secure communication network, and the second barrier control signal is communicatively connected to a near end of a second secure communication tunnel through the non-secure communication network. A far end of the first secure communication tunnel is communicatively connected to an activating input of a first barrier circuit, and a far end of the second secure communication tunnel is communicatively connected to an activating input of a second barrier circuit.
