Exchanging Data with the CPU Unit Section 3-5
3-5-4 Fixed Data Allocations
DM Allocation and
Contents The initial settings of the Analog Input Unit are set according to the data allo-
cated in the Special I/O Unit 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 Special I/O Unit DM Area words that are occupied by the Analog Input
Unit are set using the unit number switch on the front panel of the Unit. Re-
fer to
3-5-2 Unit Number Settings 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.
3. Only D(m) to D(m+5) are supported by the CJ1W-AD041-V1.
