Table 12: Master SCADA routing table
There are two routes used in this network. The first route is a single route that links RTU address 71 to radio
address 2000:01. All traffic with an RTU destination of 71 will be routed to the auxiliary port of the slave
with address 2000 (slave 1).
The second route is a mapped route that links RTU addresses 55 and 56 to radio addresses 3001:00 to
3002:00. This means that traffic destined for an RTU with an address in the range 55-56 will be routed to the
main port of the slave with address 3001 + RTU Address – 55.
All slave units have the same routing table, shown in Table 13.

6.10 SCADA Network with a Back-to-back Repeater
SCADA networks can use back-to-back repeaters in order to extend the network coverage. This scenario is
shown in Figure 23.
