The initial settings of the Analog I/O Unit are set according to the data allo-
cated in the Special I/O Unit DM Area. Settings, such as the inputs and out-
puts used, the analog input signal range, and analog output signal range must
be set in this area.

1. The Special I/O Unit DM Area words that are occupied by the Analog I/O
Unit are set using the unit number switch on the front panel of the Unit. Re-
fer to 6-3-2 Unit Number Switch for details on the method used to set the
unit number switch.
2. If two or more Special I/O Units are assigned the same unit number, a
"UNIT No. DPL ERR" error (in the Programming Console) will be generat-
ed (A40113 will turn ON) and the PLC will not operate.
