Finally, enter the if/then statements into the computer for downloading to the
Fuzzy Logic Unit.
The following table shows the I/O words allocated to Units mounted on the CPU
Rack. The unit number is set with a switch on the front of Special I/O Units.

Some of the Special I/O Units used in this system require control words. Here the
control data is written in an area of DM that is read-only from the program. This
data must be stored in DM with a Programming Console before operation.
