Word 0 is reserved for block transfer and status.
If data from the supervisory processor is intended to control outputs of the
adapter-mode processor, the ladder logic in the adapter-mode processor
must move the data from its input file (I/O rack 3 or the adapter image file)
to its output file (local I/O). Use XIC and OTE instructions for bit data;
use move and copy instructions for word data.
If you want the supervisory processor to read data from a data file in the
adapter-mode processor, ladder logic in the adapter-mode processor must
move that data to its output file (I/O rack 3 or the adapter image file) for
transfer to the supervisory processor.
