The initial settings of the Analog Output Unit are set according to the data
allocated in the Special I/O Unit DM Area. Settings, such as the outputs used,
and the analog output signal ranges must be set in this area.

Data is automatically
transferred to each unit
number when the power
is turned ON, or when
the Special I/O Unit
Restart Bit is turned ON.

1. The Special I/O Unit DM Area words that are occupied by the Analog Out-
put Unit are set using the unit number switch on the front panel of the Unit.
Refer to 5-3-2 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.
The following table shows the allocation of DM words and bits for both normal
and adjustment mode.
