I/O Data Allocations
Special I/O Unit Area Allocations and Contents
I/O data exchange for the ID Sensor Unit is performed using the words allocated to the ID Sensor Unit
as a Special I/O Unit in the Special I/O Unit Area.

• The words allocated to the ID Sensor Unit in the Special I/O Unit Area are determined by the setting of the unit number
switches on the Unit's front panel. Set unit numbers so that the same words are not allocated to more than one Unit. (Refer to
p. 63 for the setting method.)
• If the same unit number is set for more than one Special I/O Unit, a fatal error (No. duplication error on CX-Programmer or Unit
Number Duplication on Programming Console), and the PLC will not operate.
