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

Target node PLC3
Shows that communications frames from
network address 2 go to unit number 0.
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.
