(red) Unit
The CPU Unit and Analog Input Unit exchange data via words allocated to the
Analog Input Unit as a Special I/O Unit. Words are allocated to Special I/O
Units in both the CIO Area and the DM Area.
The words that each Analog I/O Unit uses are determined by the setting of the
unit number switches on the front panel of the Unit.

0 CIO 2000 to CIO 2009
1 CIO 2010 to CIO 2019

Note 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 occur (A40113 will
turn ON) and the PC will not operate.
The Analog I/O Unit exchanges data with the CPU Unit via the allocated por-
tions of the CPU Unit's Special I/O Unit Area and DM Area. The addresses
allocated in these areas are determined as follows, according to the value (0
to 95) set by the unit number switch on the front panel of the Analog I/O Unit.
• Special I/O Unit Area: 10 words from beginning word n
n = 2000 + unit number (0 to 95) x 10
Indicator

Lit Error has occurred during data
exchange with the CPU Unit, or
Analog I/O Unit's unit number is set
incorrectly, or there is a mounting
error.
