Registration Name column that were set with the Setup Interface Dialog Box.
1.
Select the desired Registration Name from the Registration Name drop-
down list in Remote Information. The following parameters are displayed
for the selected Registration Name in Remote Information.
• Network Address: The FINS network address for the DeviceNet Unit.
• Node Address: The node address for the DeviceNet Unit.
• Unit No.: The unit No. DeviceNet Unit.
• Port No.: The FINS UDP port No. for the Ethernet Unit.
• IP Address: The IP address for the Ethernet Unit.

Information on Address
Conversion
Ethernet Unit Address Conversion Method
The FINS communications service is used inside the PLC. Because there is
no IP address information added to the FINS communications service, the IP
address is determined from the FINS node address in order to send a FINS
message (command or response) with the PLC’s Ethernet Unit.
The Ethernet Unit address conversion is done by either of the three following
methods (set in the System Setup for CPU Bus Units of the CPU Unit to which
the Ethernet Unit is mounted).
• IP address table
• Automatic generation
• Combined method
The computer’s FINS node address calculation for each address conversion
method is described below.
Note
For details on address conversion, refer to the SYSMAC CS/CJ-series Ether-
net Units Operation Manual (catalog No. W343).
Address conversion
method
Computer’s FINS node address calculation
IP address table
The FINS node address is set according to the
computer’s IP address based on a preset corre-
spondence table called an IP address table.
Automatic generation
The FINS node address is automatically generated
from the computer’s IP address and the subnet
mask.
Combined method
If the computer’s IP address has been set in the IP
address table, the FINS node address in the table is set.
If the computer’s IP address has not been set in the IP
address table, a FINS node address that is automatically
generated from the computer’s IP address, or from the
subnet mask, is set.
