X-Way Routing
Messaging
With Multi-Coupler Stations
Messages intended for a network are sent to the coupler connected to the destination network. The configuration phase allows the destination coupler to be determined.
Specific case
Messages intended for a network with an unknown address are sent to the network with the main address of the station, along with messages whose network number is 0.
Example:
All messages intended for network 3 are sent to the coupler with module address 4, and those whose destination network is 1 to the network link integrated into the processor.
All messages whose network number address is different from 1 or 3 are sent to the processor that manages the main network.
In a multi-coupler architecture, communication is limited to a single network level.
With Bridge Stations
Messages intended for a network are sent to the coupler that has access to this network. The configuration phase allows determination of the accessible networks for each coupler of the station.
Specific case
Messages whose network number is 0 are sent to the network with the main address of the station.
