What is power line communication?
It is a system for carrying data on a
conductor.
 It uses the existing power lines to transmit
data from one device to another.
 This makes power line communication one
of the best means for networking.

How power line communication
operates

It operates by impressing a modulated carrier
signal on the wiring system.

Data rates over a power line communication
system vary widely.
Some control networks in power line
communication

CEBUS

LonWorks

LnCP

HNCP
CEBUS

LAN network provides communication between
of control information and services among
devices.
LonWorks

LonWorks consist of all nodes that
communicate with one another over a variety of
communications media using LonTalk protocol,
a common message-based communications
protocol
LnCP

A peer-to-peer communication model is used in
this network.

it is a multi-master system
HNCP

This protocol provides standard message set of
devices.

has to be compact to enable the use of lowbandwidth network media .

The range of devices applying this protocol
reaches all the electric machines that are
connected by PLC .
