5.7.3    Exercise 3   FMOV 

Create a program in which turning on X0 turns on the 64 outputs Y40 to Y7F and 

turning off X0 turns off the 64 outputs Y40 to Y7F. 

 

Create the following program with GX Works2 filling in the blanks            . 

Then, check the operation using the demonstration machine.
