Hi all 

I have a switch converter from decimal to binary system 

I want το connect the output off the binary code off this converter  switch, the four signals from the units into the four inputs off the logo similarly the other eight signals by the tens and hundreds off switch in others 8 inputs off logo .

that will use the total 12 inputs 

 I want if choose the value to the switch e.g 150 to use as a set value for a counter down 

I want to ask is there a ready program in logo for this purpose or a converter from binary to decimal ?
