Selected feature values for this example program have been recorded in
Worksheets 1 and 2 (NO TAG and Figure B.5, respectively). Worksheet 1
shows the dynamic block (data table words 257-277

8

). The PID module

word numbers correspond to the position numbers on the display and are
numbered W01 through W17. Worksheet 2 shows the loop 1 block (data
table words 300-322

8

). The PID word numbers (position numbers) are

W18 through W36. Also refer to the data table map (NO TAG) which
shows the locations of the consecutive data blocks.
