4-1-2 Setting the Unit Number
Set the unit number for each Unit using the rotary switches on the front of the
Unit. When using Controller Link Units in duplex operation, set the same unit
number for each active/standby pair of Units. The unit number is used to iden-
tify a CPU Bus Unit in the PLC. Any unit number can be set between 0 and F
in hexadecimal (00 to 15 in decimal).
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. If there are no Units used in duplex operation, 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 Units, and the CPU Unit will not be able to
recognize the Units. If there are Units used in duplex operation, they will be
recognized when the duplex settings have are made and the I/O tables rec-
reated.
4. When there are Controller Link Units used in duplex operation, if different
unit numbers are set for an active/standby pair of Units, they will not be rec-
ognized as a pair, and will not operate properly.
5. When the Unit is recognized by the PLC’s CPU Unit, “Controller Link Unit
(NS)” will be shown in the I/O table displayed at the CX-Programmer.
6. The default setting is “0.”
7. The unit number determines the DM parameter area used by the Controller
Link Unit in PLC memory.
