Set the unit number for each Unit using the rotary switches on the front of the
Unit. The unit number is used to identify a CPU Bus Unit within the PLC. Any
unit number can be set between 0 and F in hexadecimal (00 to 15 in decimal).

Setting range
Node
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
1. Always turn OFF the PLC's power before setting the unit number.
2. When setting a Unit for the first time or changing the existing setting, create
a I/O table in the PLC's CPU Unit.
3. Do not set the same unit number twice within the same PLC. An error will
occur if the same unit number is set for two different Unit, and the CPU Unit
will not be able to recognize the Units.
4. When the Unit is recognized by the PLC's CPU Unit, "NS" will be shown in
the I/O table displayed for the CX-Programmer programming device.
