Abstract

PURPOSE:To reduce the number of wirings in the supervisory operation panel and improve their noise proofness by connecting input and output devices and selection switch groups with one pair to three pairs of common signal lines using time division pulse signals through control circuits. CONSTITUTION:The control chart channels C1 to CN to control switches with time division pulse signals are set up in the selection switches (Nos. 1 to N) of the supervisory operation panel 1 and are connected with the input and output devices 4, for example, using single wire type common signal lines 7. For instance, in the control circuit C the start signal for resetting the counter 9 and the pulse clock of bits PL1 to PL4 are detected from the 4-bit time division pulse signal of the input and output device and applied to the counter 9. The distributor 14 obtains the address matching input command and performs decoding. The data long code bit is detected and the flashing of the lamps L1 and L2 is controlled in accordance with the PL1 and PL2 data. The on/off control and malfunction of the switch S1 are also detected in accordance with each output of bits PL3 and PL4.
