In very large SCADA systems spread over a

wide geographical area, it might be neces-

sary to have alternative communication lines

or back-up communication lines if the pri-

mary communication line is damaged, fails

or needs service.

Connecting routers as shown above can

solve this.

If the routers are configured as logical re-

peaters, they will work as isolating objects

for the substation if failure occurs on the

communication lines. Then the main station

can use the primary communication line for

one part of the network and the back up (re-

dundant communication line) for the other

part of the network.

The universal router module is used for

connecting different channels in

LONWORKS ® networks. A router is an ac-

tive device receiving messages and send-

ing messages.

In large networks the router is therefore

used as a logical repeater, e.g. in situations

when more than two physical repeaters

would be needed. This application mode is

needed where the distance between nodes

exceeds the constraints specified by the

transceiver designer.

Because of the active message processing

by two Neuron ® chips, a delay in transmis-

sion between both sides has to be kept in

mind.
