Bcd

Hi I'm trying to understand how binary coded decimal works. Does anyone have a programme written in Rs logix 500 so I can see an example.

Thanks

BCD for an example uses the first 4 (0-3) bits of the ie. Input word.
The remaing 12 bits can be used for any other purpose.

use the binary truth table to decode

0000=0
0001=1
0010=2
0011=3
0100=4
0101=5
0110=6
0111=7
1000=8
1001=9
and so on, this is all you would need for a single thumbwheel.

I hope I explained this right.

Hi Paul,

This is from the AD manual but it may help....

this post about thumbwheels and BCD might be helpful as a simple example ...
