Relay Network Table
To go to network address 3, first it is
necessary to go to node address 3 in
network address 1.
The relay network table indicates the network address and node address of the first
relay node when data is being sent to a destination network other than a network to
which the PLC is connected. The destination network is reached by following these
relay nodes.
Example:
from PLC1 (network address 1, node address 1) to PLC4 (network address 3, node
address 2).
Cases when a Relay Network Table Is Required (Local Network Table also Required)
When routing tables are required, both local network tables and relay network tables
must be set.
