  • Patent number: 11106234
    Abstract: An input/output apparatus for a PLC includes at least first and second sub-systems. In each sub-system, a DC-DC converter controls a voltage of an external power supply to a target voltage by switching a PWM signal, and a microcomputer is driven by a clock signal. In the microcomputer, a PWM signal generating unit generates the PWM signal and a frequency analyzing unit samples an inputted voltage at a cycle shorter than a cycle of the PWM signal, and analyzes the frequency of the inputted voltage. The frequency analyzing unit acquires a frequency of the PWM signal from the frequency of the inputted voltage, calculates a frequency of the clock signal, and outputs an abnormality-notifying signal when the frequency of the clock signal falls outside a prescribed range. An output voltage of the DC-DC converter of the first sub-system is inputted to the frequency analyzing unit of the second sub-system.

  • Publication number: 20210034045
    Abstract: An input module of an industrial control apparatus receives a digital signal from an external source, outputs a binary signal as an internal signal, and determines a level of the digital signal based on the internal signal. The input module determines that the digital signal has a low level when a low level of the internal signal continues for a certain time period, determines that the digital signal has a high level when the internal signal switches from the low level to a high level and then switches to the low level again, and determines an occurrence of a fixing failure when the internal signal switches from the low level to the high level and then fails to switch to the low level again.
