4-2-2 Unit Number

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).

No. Note: The factory default settings are shown.

Item	Specifications
Setting method	Single-digit hexadecimal
Setting range	0 to F (decimal 00 to 15, default is 0)
Node	All nodes in the Network

Set the node address using a small flat-blade screwdriver, being careful not to damage the rotary switches.

Note 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.
