IMPORTANT
All bit numbers in this example are in octal. The
1746 16- and 32-point modules must have their LED
numbers and wiring terminal numbers labeled in
octal. All Series C or later modules include an octal
conversion kit which allows you to convert from
decimal to octal. This kit is also available as a
replacement part through your Rockwell Automation
distributor.
