network. To remedy this attenuation problem and obtain an optimum and com-

plete PLC signal coverage for a building, it may be useful to install devices called

“repeaters” in order to extend the PLC network to the areas of the electrical net-

work where the PLC signal attenuation is too high.

This section gives a configuration example for a repeater device used for extend-

ing the installed PLC network. The concept of a repeater device is correlated with

that of a PLC network segment.

The architecture illustrated in Figure 11.9 includes the following PLC devices:

•

PLC1 and PLC2 are PLT300 Oxance products active in PLRP mode specific

to Oxance, which can be administered by means of a Web interface on the

Ethernet network interface.

•

PLC3 is a PLT320 Oxance product active in PRLP mode used for repeating

the PLC signal over the electrical network. For this purpose, it has two

HomePlug PLC interfaces but no Ethernet interface and can be administered

by means of the PLC1 or PLC2 Web interface.

•

PLC4 and PLC5 are usual passive HomePlug PLC products that cannot be

connected to PLC1 and PLC2 without a repetition system.

Figure 11.10 gives a logical representation of this network with the various net-

work segments connected to each other in order to provide a continuous PLC net-

work on the entire electrical network.

The PLT320 has an IP address of 192.168.1.251. Once the configuration PC is

correctly adjusted to be on the same IP network (192.168.1.100, for example), the

connection is possible using the network password (default value is 0 ex works).
