Programming Considerations for PLC-5 ProcessorsF–12
Publication
65566.5.1 - October 1996
For example, if your first assigned timer in your program has the
address T4:99, the processor allocates storage for timers T4:99 down
to T4:0 whether you use them or not. Since each timer address uses
three words (timers are 3-word elements), your timer address of
T4:99 has created a 300 word data storage file.
As another example: if you assign the address N7:9 to store a word
(or element), the processor opens a file from that address down to
zero or down to the next lower assigned address. If the next lower
address was N7:3, address N7:9 would include all words down to
N7:3 (Figure F.5).

Use this template for your appendices. If it were not for the different
running head, this would read like any other chapter.
