This form can be used to write functional descriptions of word addresses
used in the data table for word storage, timers and counters, etc.
The form is divided into two 32-word columns. The words can be
numbered consecutively through the entire 64 words. Or, the right-hand
column can be numbered 1008 greater than the left-hand column to
conveniently track accumulated and preset values. In either case, the
lowest digit of the 3-, 4- or 5-digit word address is prenumbered, 0-7.
For example, a portion of the data table word assignment sheet is shown
in Figure 3.10. It illustrates timer and counter functional descriptions for
accumulated values starting at word address 200
8
and preset values starting
at 300
8
. A 20 and 30 were written into the left-hand and right-hand word
address boxes, respectively.
