2 Instruction Descriptions
*8 The valid range depends on whether you specify the built-in EtherNet/IP port or an EtherNet/IP Unit for UnitNo (Unit num-
ber). Refer to Function, below, for details.

Function
The ChangeIPAdr instruction changes the IP address of the built-in EtherNet/IP port, internal communi-
cation port, or EtherNet/IP Unit that is specified with UnitNo (Unit number) according to IP address
assignment method and setting timing BootPControl.
If you specify the built-in EtherNet/IP port with UnitNo, the port goes to link OFF status when execution
of the instruction ends and then goes to link ON status with the new IP address.
If the internal communication port is specified with UnitNo, the _EIPIn1_EtnOnlineSta system-defined
variable changes to FALSE when execution of the instruction ends. Communications with the new IP
address is enabled when the variable changes to TRUE. If you specify an EtherNet/IP Unit with UnitNo,
the EtherNet/IP Unit is restarted when execution of the instruction ends. Communications with the new
IP address is enabled when restarting the Unit ends.
You can use this instruction to change the IP address of the built-in EtherNet/IP port, internal communi-
cation port, or an EtherNet/IP Unit from an HMI.
The data type of UnitNo is enumerated type _eUnitNo. The meanings of the enumerators are as fol-
lows:
Enumerator
*1
_CBU_CPU
_CBU_CPU_Port1
_CBU_CPU_Port2
_CBU_CPU_InPort1
_CBU_No00 to _CBU_-
*5
No15
*1 Specification is possible for an NJ-series CPU Unit.
*2 Specification is possible for an NX-series CPU Unit or an NY-series Controller. You can spec-
ify _CBU_CPU instead of _CBU_CPU_Port1.
*3 Specification is possible for an NX-series CPU Unit. You cannot use it for CPU Units without
communications port 2.
*4 Specification is possible for an NY-series Controller.
*5 Specification is possible for an NJ-series CPU Unit.
