Output Data (Block Transfer Write)
Use a format similar to input data (Figure A.9). Reserve eight words of
output data for each full remote I/O chassis. Do not use the first eight
words. Remote I/O addresses corresponding to rack numbers 1 and 2 start
at words 10 and 20 octal, respectively.
Block Transfer Write File
Assign write block transfer file for sending output data via the 1771-SN to
the PanelView terminal. Output data for rack 1 uses words 10 through 17
octal, and rack 2 uses words 20 through 27 octal. For example, you could
assign a write file at 200 through 227 (octal). Choose your own method for
moving output data into the BTW file.
