摘要： An intermediate station transmits a supervisory signal sent form a given controlled device to a controlled device associate with the given device as a control signal. An intermediate-station input unit extracts a supervisory signal, which is a current signal superimposed on a signal transmitted through a data signal line, in every clock cycle. An intermediate-station output unit obtains the supervisory signal in every clock cycle, and outputs a control signal, which is a pulse-width-modulated voltage signal, onto the data signal line in the same clock cycle in which the supervisory signal has been extracted.

摘要： A master station has a master-station transmission circuit that extracts a serial monitor signal so as to convert a control data signal into monitor data by changing a duty ratio of negative and positive voltage-level periods, converting the control signal into a serial pulsing voltage signal, transmitting a monitor data signal that is superimposed on the serial pulsing voltage signal, and detecting the presence or absence of a signal of a current that flows during the negative and positive voltage-level periods. A plurality of slave stations respectively have a slave-station transmission circuit that identifies a duty ratio of the positive and negative voltage-level periods relative to each serial pulsing voltage signal, that extracts a control data signal so as to output the data to a controllable unit of the slave station.

摘要： Disclosed are a photoelectric sensor and a photoelectric sensor system capable of accurately detecting an object without being affected by disturbance even though the object is very thin. A photoelectric sensor according to an embodiment of the invention includes a light emitting unit and a light receiving unit. The photoelectric sensor detects whether there is an object between the light emitting unit and the light receiving unit based on a variation in the intensity of a light signal received by the light receiving unit. The light receiving unit receives a light signal that is emitted from the light emitting unit to the light receiving unit without intersecting the object and a light signal that is emitted from the light emitting unit to the light receiving unit through the object, and is operated in synchronization with a light emission timing signal of the light emitting unit. The intensity of the received light signal that is not attenuated by the object is compared with the intensity of the received light signal that is attenuated by the object to detect information indicating whether there is the object.
