ControlNet Media Components

ControlNet network media components provide flexibility when designing a
communication network for a particular application. A ControlNet network
consists of a combination of the media components listed in the following
table.
Table C.1 ControlNet Media Components
Component Definition
Trunk cable A bus or central part of a network media system that serves as a
communication channel between any two points on a network.
Cable connector A piece of hardware for mating and demating network media and
devices.
Repeater A piece of hardware that receives a signal on a cable, amplifies the
signal, and then retransmits it along the next segment of the cable.
Terminator A piece of hardware attached to the end-points of a network to
absorb signals so that they do not reflect back to create interference
with other signals.
Tap A piece of hardware that acts as a communication link between the
network and a device, extracting a portion of the signal from the
trunk cable.
Node A connection point with the programmed or engineered capability to
recognize and process incoming data or transmit data to other
nodes.
