PURPOSE:To control a lot of loads from an operation section suitably, by inputting each circuit output of a switching device, selecting the latch timing with the counter output and applying the output of each latch to a control output terminal corresponding to individual modes. CONSTITUTION:An address coincidence output of a terminal device main body 1 is inputted to a counter 7, control outputs 1-5 of the main body 1 are inputted to inputs 1-5 of a control switching device 8 and switched and connected to the output of two groups A, B comprising A1-A5 and B1-B5 with the input of a control CONT. The output of the counter 7 is given to the monitor input of the main body 1, transmitted as a return signal to the operation panel side and the mode of the main body 1 is informed to the operation panel. Latches 9A, 9B receives the output of the groups A, B of the switching device 8, and the latches 9A, 9B perform latch operation by the logical product between an NOT output of the counter 7 and the address coincidence output and between the output of the counter 7 and the address coincidence output respectively. |
