Allocations for Normal
Mode
I/O refresh data for the Analog Output Unit is exchanged according to the allo-
cations in the Special I/O Unit Area.
I/O refresh
At the I/O refresh by the
PLC, outputs (CPU to
Unit) and inputs (Unit to
CPU) are refreshed in
order with every cycle.

1. The Special I/O Unit Area words that are occupied by the Analog Output
Unit are set using the unit number switch on the front panel of the Unit. Re-
fer 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.
For normal mode, with CJ1W-DA021/041 Units, set the operation mode
switch on the front panel of the Unit as shown in the following diagram. (The
CJ1W-DA08V/08C does not have this switch. Change the mode by setting bits
00 to 07 in D(m+18) to 00 hex.)
The allocation of words and bits in the CIO Area is shown in the following
table.
