Abstract
PURPOSE: To enable to input a number of signals with the sequence controller having less number of input points, by selecting the input common line with the pulse from the output section of sequence controller.
CONSTITUTION: The output section 3 of the sequence controller adds the pulse train to the counter 51. The counter output selects the common lines COM1WCOM15 via the selection output section 7. Simultaneously, the encoder 61 delivers the code information representing which common line is selected to the input section 1 of the sequence controller via the lines EX1WEX4. The contact information R1,1WR15,44 of 660 sets are fed to the input section 1 via the lines D11WD144 corresponding to the common lines. As this example, the contact information of 660 sets can be inputted to the sequence controller having the input lines of eight.
