Blank CCB Worksheet for Your Application
Write your own entries in this blank worksheet to suit your application.
Important: Because we cannot predict the number of bit, numeric, or ASCII
entries in your application, we give you a blank word column and extra rows
for each type of entry. Enter the number of the file word for each entry, and
use blank rows as needed. Enter device ID and data in the formats that you
specified in MCC word 1 bits 8-10. See notes [1] and [2] below.
