I/O Communication Setting – Input Setting
D
Set whether the controller CPU exchanges the input data with the EtherNet/IP.
When a checkmark is entered, data exchange is not performed.
Instance No. [IN]
Set an input instance number in the following range.
Scanner: 1 to 65534
Adaptor: 100 to 199, and 768 to 1279
ΠWhen 198 is set for the device set as Adaptor, entry in the Size field is disabled and 0 (bytes) is assigned.
ΠDuplication of the input instance numbers and output instance numbers is checked. When Scanner is selected,
the instance number and the size must agree with those set at the remote station. For details, refer to
4.2.2 ( 2 ) Cautions on Setting Instance No. [IN] and Instance No. [OUT] on page 4-8.
Input Register
Set the leading address of the input area (input register IWxxxx) to be allocated to the corresponding device as a
hexadecimal word. The setting range is 0 to 7FFF.
Size (Byte)
Set the size of the input area (input registers IWxxxx to IWyyyy) to be allocated to the corresponding device in
bytes. The setting range is 1 to 500 bytes.
„
I/O Communication Setting – Output Setting
D
Set whether the controller CPU exchanges the output data with the EtherNet/IP.
When a check mark is entered, data exchange is not performed.
Instance No. [OUT]
Set an output instance number in the following range.
Scanner: 1 to 65534
Adaptor: 100 to 199, and 768 to 1279
Duplication with other instance numbers (IN/OUT) is not allowed.
ΠWhen 198 is set for the device set as Adaptor, entry in the Size field is disabled and 0 (bytes) is assigned.
ΠDuplication of the input instance numbers and output instance numbers is checked. When Scanner is selected,
the instance number and the size must agree with those set at the remote station. For details, refer to
4.2.2 ( 2 ) Cautions on Setting Instance No. [IN] and Instance No. [OUT] on page 4-8.
Output Register
Set the leading address of the output area (output register OWxxxx) to be allocated to the corresponding device
as a hexadecimal word. The setting range is 0 to 7FFF.
Size (Byte)
Set the size of the output area (output registers OWxxxx to OWyyyy) to be allocated to the corresponding device
in bytes. The setting range is 1 to 500 bytes.

I/O Communication Setting – Others
Scan
Select the scan timing with which the controller CPU exchanges the I/O data with the EtherNet/IP from High and
Low. The data exchange cycle of the controller CPU is asynchronous with I/O transmission.
High: The I/O data is exchanged at the high-speed scan timing of the controller CPU.
Low: The I/O data is exchanged at the low-speed scan timing of the controller CPU.
