3-2-2 Unit Number Switch
The CPU Unit and Analog Output Unit exchange data via the IR area and the DM
area. The IR and DM word addresses that each Analog Input Unit occupies are
set by the unit number switch on the front panel of the Unit.
Always turn off the power before setting the unit number. Use a flat-blade screw-
driver, being careful not to damage the slot in the screw. Be sure not to leave the
switch midway between settings.
