Additional remarks Whether an output is a positive output or a negative output, and whether there is one four-digit seven-segment display or two four-digit seven-segment displays depend on n . The outputs on the PLC should be NPN transistors whose collectors are open collectors. In addition, an output has to connect a pull-up resistor to the DC power supply (less than 30 VDC).
Therefore, when an output is ON, a signal of low potential is output. _6 The following table shows the negative logic. 6-522 Y0 Y1 Y2 Y3 Y4 Y5 Y6 Y7 Y10 Y11 Y12 Y13 C0 Binary-coded decimal value Output (Binary-coded decimal code) Signal b3 b2 b1 b0 8 4 2 1 A B C D 0 0 0 0 0 0 0 0 1 1 1 1 0 0 0 1 0 0 0 1 1 1 1 0 0 0 1 0 0 0 1 0 1 1 0 1 0 0 1 1 0 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 1 0 1 1 0 1 0 1 0 1 0 1 1 0 1 0 0 1 1 0 0 1 1 0 1 0 0 1 0 1 1 1 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 0 0 1 1 1 1 0 0 1 1 0 0 1 0 1 1 0
