Abstract: PROBLEM TO BE SOLVED: To attain miniaturization by setting an ID number of a telecontrol device so as to select a communication form thereby eliminating the need for a setting switch. SOLUTION: A microcomputer μC3 has a communication form selection means 3a, a data transmission means 3b, and a data reception means 3c and connects to a serial input output section 4. A telecontrol device 1 is provided with a storage section 11 storing an ID code. Then the input telecontrol device 1 and an output telecontrol device are used to attain 1-1 simplex transmission and an on/off signal is sent in a radio wave. Then a one-way communication form and a two-way communication form are selected depending on the ID code set to each telecontrol device. When there is any idle channel without a carrier, the ID code and the data of the input telecontrol device are sent to the receiver side.

Abstract: PROBLEM TO BE SOLVED: To decide signal transmission path abnormality caused by a connection failure, etc., of a connector means with a simple configuration in a connection type sensor system provided with a sensor unit string for bidirectionally transmitting data with a bucket-brigade method through the connector means and a communication unit for connecting one of sensor unit strings to a network of an FA system. SOLUTION: Sensor units are respectively provided with a two-way communication means. On the other hand, the communication unit side is provided with the number of connected sensor units information holding means for holding the number of connected sensor units information which is optionally set in advance, and an abnormality deciding means for sequentially designating each sensor unit to transmit a particular command, meanwhile, counts the number of connected sensor units in accordance with the existence/nonexistence of a prescribed response to the particular command, and decides signal transmission path abnormality of the sensor unit string on the basis of collation of the counted number of connected sensor units with the preheld number of connected sensor units information.

Abstract: PROBLEM TO BE SOLVED: To transmit data from plural input devices to an output device by transmitting data inputted at the time of detection when a transmission command including an ID code matching its own ID code is received. SOLUTION: A setting part 6 is provided with a setting function for setting the ID code of a telecontrol device. The ID code which is set is held in an ID storage part 11. An output telecontrol device sequentially transmits the transmission commands following the ID codes of an input telecontrol device 1. When the input telecontrol device 1 receives the self ID code and the transmission command, it transmits input data from a data transmission means 3a. The output telecontrol device receives the signal and outputs the OR signal of the received signal. Thus, the signals can be sequentially transmitted from the input telecontrol device 1 in accordance with the transmission command from the output telecontrol device 1.

Abstract: PROBLEM TO BE SOLVED: To provide a connection type sensor system for accurately monitoring a light receiving quantity level of a photoelectronic sensor with a fixed condition. SOLUTION: Each sensor unit has a connector means for signal transmission between adjacent sensor units, a two-way communication means for two-way data communication between the adjacent sensor units, a light projecting and receiving means for object detection, a light receiving quantity current value generating and holding means for generating a representative value of a light receiving quantity level for on and/off term and holding the representative value while updating the representative value as a light receiving quantity current value at appropriate update timing, and a command correspondence processing means for returning a light receiving quantity current value held at the point of that time as a response to a particular command to an adjacent photoelectronic sensor unit on a command arriving side through the two-way communication means when the particular command received from a sensor unit of one adjacent side through the two-way communication means designates a self- machine, and transmitting the command to a photoelectronic sensor unit on the other adjacent side through the two-way communication means when the command does not designate the self-machine.

Abstract: PROBLEM TO BE SOLVED: To provide an analog input terminal by which the need for the user to correct a program is eliminated by correcting an error of a voltage (current) and outputting a digital value even when receiving an analog signal with the voltage (current) with the error from an analog output device. SOLUTION: An analog input circuit section 10a capable of receiving signals of 4 channels outputs an analog signal (x) received from an analog output device to an A/D converter section 10b. When receiving the analog signal (x) from the analog input circuit section 10a, the A/D converter section 10b converts the analog signal (x) into a digital value that is called a raw count A and outputs it to a CPU section 10c. The CPU section 10c outputs a digital signal X obtained by normalizing the raw count A received from the A/D converter section 10b into a range of 0-6000 to a master station based on a calibration value α and an adjustment value β that are stored in an EEFROM 140 and mentioned later.

Abstract: PROBLEM TO BE SOLVED: To perform multi-channel access for automatically selecting a free channel from the prescribed number of channels without using a specified frequency control channel. SOLUTION: A telecontrol device 1 for input successively receives determined channels, discriminates the presence/absence of carriers and selects the free channel by a channel selection means 3a. An ID code and data are transmitted by the selected free channel. At the time of receiving the channel provided with its own ID code, the telecontrol device for output fixes a reception channel and receives the data by the channel.
