The initial settings of the Analog Input Unit are set according to the data allo-
cated in the Special I/O Unit Area in the DM Area. Settings, such as the inputs
used and the analog input signal range must be set in this area.
The conversion time and resolution can be set, along with the operation
mode, in DM word m+18.

Note 1. The words in the Special I/O Unit DM Area that are allocated to the Analog
Input Unit are determined by the setting of the unit number switches on the
front panel of the Unit. Refer to 3-5-2 Unit Number Setting for details on the
method used to set the unit number switches.
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.
3. Only D(m) to D(m+5) are supported by the CJ1W-AD041-V1.
