Setting the Routing Tables

This section explains how to make the necessary settings when transferring the FINS
local routing tables to a PLC connected directly by a serial connection.
3-2-1

Routing Table Setting Example

This section explains how to create and transfer the FINS local routing tables for the
following network structure.
Example: Routing from PLC1 to PLC3
Local node PLC1
Node address 1
(Unit number 0)
Transfer routing
table required in
PLC1.
PLC1 Local Network Table
Unit number
Go through unit number 0 to send to
network address 1.
PLC1 Relay Network Table
Destination
network
address
To go to network address 2, it is necessary to
go to node address 3 in network address 1.
All of the following routing tables must be created and transferred for this example
network.
PLC1

Node address 1
(Unit number 5)
Network address 2
Transfer routing

Target node PLC3
Node address 2 (Unit number 0)
Send to node address 2 in
network address 2 to send
to target node.
Transfer routing
table required in
PLC3.
PLC3 Local Network Table
Unit number Local network address
0 2
Shows that communications frames from
network address 2 go to unit number 0.
PLC3 Relay Network Table
Destination Relay network

The communications result must be returned to
PLC1 as a response. To go to network address
1, first it is necessary to go to unit number 0 in
network address 2.
