7.8.2 When BCD instructions are used
This subsection gives examples of wiring for displaying the current value of D100 on the 2-digit 7-segment
display.
1. Main unit
Example of program
Example of wiring
1) In the case of sink wiring
Use the sink only input, sink only output type main unit.
The wiring example is the FX
3UC-32MT/D or FX3UC-32MT-LT.
2) In the case of source wiring
Use the sink/source common input, source only output (transistor output) type main unit.
The wiring example is the FX
3UC-32MT/DSS.
