5.7.6 Exercise 6 Multiplication and division instructions
Create a program that:
1) Sets data for multiplication and division when X0 is turned on.
2) Multiplies the value specified by the digital switches X20 to X27 by the value
specified by the digital switches X30 to X37 in binary when X2 is turned on.
3) Divides the value specified by the digital switches X30 to X37 by the value
specified by the digital switches X20 to X27 in binary when X3 is turned on.
4) Outputs the result of the multiplication or division to the BCD displays Y40 to Y4F
and the remainder to the BCD displays Y60 to Y67.
(X30 to X37) × (X20 to X27)
(Y40 to Y4F)
(X30 to X37) / (X20 to X27)
(Y40 to Y4F) ... (Y60 to Y67)
Create the program with GX Works2 filling in the blanks in the following.
Then, check the operation using the demonstration machine.
