Creating Routing Tables Section 3-9
3-9-1 Routing Table Overview
The routing tables describe the transmission path for FINS messages when
the FINS communications are used. It consists of two tables: A local network
table and a relay network table.
Local Network Table The local network table is a table describing the correspondences among unit
numbers of the Communications Units and Boards mounted to each node
(PLC or FA Computer).
Note 1. The unit number is set (from 0 to F: 1 to 15) by the rotary switch on the front
of the FL-net Unit.
2. The network address is the number of the network (from 1 to 127) to which
the Communications Unit or Board is connected. It is set when the local
network table is created.
Relay Network Table A relay table is a table that shows the nodes to which data should be sent first
in order to send data to a network that is not connected to the local node. It
shows the correspondence between the address of the final destination net-
work, and the network address and node number of the first relay point of the
path to reach there. When internetwork communications are carried out, the
end network can be reached by following the relay points.
