7-5-5 Conversion Table for IP Addresses and FINS Node Addresses
When a UDP/IP address has been used on the Ethernet an IP address must be
used for the specified node address. Communications using FINS commands
use a FINS node address. The conversion between the IP address and the FINS
node address is made in the PC Card Unit. The conversion table for IP
addresses and FINS node addresses shows the correspondence between
FINS node addresses and IP addresses.
Specify IP addresses in decimal notation. If 0 is added to the beginning of each
field, the address will be interpreted as an octal number. Enter an space between
the IP address and node address.
When using only the socket communications, also register the IP-FINS node
address conversion table of the local node.
7-5-6 FINS Routing Tables
The FINS routing tables are required to return responses to FINS commands
sent from a computer or CV-series PC on another network to the PC Card Unit.
They show the route to each network to which response is to be returned.
The FINS routing tables consist of a local network table and a relay network
table.
Note Even if there is only one network, always specify the local network table. If the
PC Card Unit is to communicate with a node on another network, the relay sta-
tion must be a CV-series PC.
If routing tables are already set for C200HX/HG/HE Programmable Controllers,
the PC Card Unit will use those routing tables. Routing tables established by the
setup software will be invalid.
Local Network Table Specify the unit no. of the PC Card Unit and the network address of the network
to which the PC Card Unit is connected.
•
Local network address: Address of the network to which the PC Card Unit is
connected (1 to 127)
•
Unit no.: 0 (fixed)
Relay Network Table The relay network table shows the route to each network with which the PC Card
Unit is to communicate. This table need not be specified if the PC Card Unit is to
communicate only with nodes within the local network.
•
End network: Address of the network on which the destination node resides
(1 to 127)
•
Relay network: Address of the network linking the local node to the next relay
node (1 to 127)
•
Relay node: Address of the relay node between the relay network and the
end network (Ethernet Unit: 1 to 127)
To edit the routing tables, select “6. Edit Routing Table for FINS” from the main
menu of the setup software. Refer to 7-6 Setup Software Operation for details on
how to edit the routing tables.
