MultiHop Ethernet Data Radio Overview

The MultiHop Ethernet Data Radio system provides extremely reliable communication in large plants, over long distances, or

through difficult terrain. A network can easily cover many square miles and has a raw bit rate of 300Kbps.

All radios can be configured as a master, repeater, or slave radio.

Master Radio: Every network has only one master radio and all data is routed to or from the master. Because of this, the network

will have better throughput if the master radio is connected to the PLC or HMI that generates the most data traffic.

Repeater Radio: Repeater radios are slaves that also repeat. Although it is possible to use many repeaters in a network, it is usually

better to carefully define only a few devices as repeaters to help the network form faster and result in fewer repeated messages.

Repeating a message many times unnecessarily slows down the network. Repeater radios should be stationary and always on; a

moving or powered off repeater causes a slight delay in communications while the network reforms through other repeaters.

Slave Radios: Slave radios cannot repeat and are used at the endpoints of the network. Mobile radios and radios that may not

always be on while the network is in use should be configured as slave radios to prevent other devices from attempting to connect

through them to the master.

The MultiHop Ethernet data radio may operate in either star topology mode or in MultiHop topology mode.

At the center of the wireless star topology is the master radio. All wireless traffic is managed by the master and messages can only

be sent to or from the master. If a data packet needs to get from one slave to another slave it is routed through the master. In a star

topology network, the master radio is the parent and all slave radios are the children.

For the simple example star topology network shown, the following relationships exist:

•

Radio 1 is the Ethernet master radio.

•

Radios 2 through 6 are the Ethernet slave radios.
