    IPC: G01R31/327

    CPC classification number: G01R31/3278

    Abstract: A monitoring device monitors an abnormality in number of times of repetition of opening/closing of an output signal of a relay, and identifies a cause of the abnormality if the abnormality in number of times of repetition of opening/closing of the output signal of the relay is detected. This monitoring device includes an output signal monitoring unit that monitors an abnormality in number of times of repetition of opening/closing of an output signal of a relay, and a cause identification unit that identifies a cause based on periodicity of repetition of opening/closing if the output signal monitoring unit has detected an abnormality in number of times of repetition of opening/closing. The relay is opened/closed based on a control signal received from a numerical control device, and the cause identification unit may determine occurrence of an abnormality in the control signal if periodicity of repetition of opening/closing is detected.

    Abstract: A key switch on a machine control panel is provided with two contacts such that the machine control panel can include two independent communication circuits. Signals from a double-contact key switch are received by the two communication circuits, and safety-related signals are transmitted from the communication circuits to a numerical controller through a bus. The signals received by the numerical controller are compared with each other so that they can be made to comply with the safety standards by monitoring the integrity of the safety function.
