The Unit Number Setting Switch sets the EtherNet/IP Unit's unit number as a
CPU Bus Unit. The unit number determines which data area words are allo-
cated to the Unit to contain data such as control bits, flags, status information,
and connection information.
Setting method
One-digit hexadecimal
Note The unit number is factory-set to 0.
The unit number can be set to any number in the setting range (0 to F), as
long as the same number is not set on another CPU Bus Unit in the same
PLC.
(1) Use a small screwdriver to make the setting, and be sure not to damage
the rotary switch.
(2) Always turn OFF the PLC's power supply before setting the unit number.
(3) The unit number is factory-set to 0.
(4) If the same unit number is set on more than one CPU Bus Unit mounted
in a PLC, a unit number duplication error will occur in the PLC and the
EtherNet/IP Unit will not be able to start operating.
The Node Address Setting Switch sets the EtherNet/IP Unit's node address.

X16 X16
Setting method
Two-digit hexadecimal
Note The node address is factory-set to 01. With the default settings, the values set
on these switches become the last two digits of the EtherNet/IP Unit's IP
address.
Default IP address = 192.168.250.node address
With the factory-default node address setting of 01, the default IP address is
192.168.250.1.
