12.3.2 Routing function
The routing function is used to execute transient transmissions to stations having other
network numbers in a multiple network system.
In order to execute the routing function, it is necessary to set the "routing parameters"
to associate the network numbers of the request source and the station that will
function as a bridge
1
between the networks.
1: The bridge function refers to sending data via an adjacent network.
POINT
MELSECNET/H board cannot be used as a relay station that function as a bridge.
Use the network module for the relay station.
(1) Stations that require routing parameter setting
(a) The setting is required for both the transient transmission request source
and relay stations.
(b) For the relay stations, two routing settings are required: one from the
request source to the request destination, and the other from the request
destination back to the request source.
(c) The setting is not required for the request destination.
In the example shown in the diagram below where the transient transmission is
executed from 1N
S
3 to 3N
S
4, the setting is required for the following three stations:
1) Setting for 1N
S
3 that requests the transient transmission
Designate the network number (3) of the Transfer to, the relay station
(1N
S
4), and the relay network number (1) to the relay station.
2) Setting for 1N
S
4 that functions as a bridge
Designate the network number (3) of the Transfer to, the relay station
(2N
S
4), and the relay network number (2) to the relay station. It is not
necessary to set the return route because it is designated in the setting
for 2N
S
4.
