Ethernet is one of the most popular network technologies in use today. The major reasons for
Ethernet’s popularity is a suitable mix of speed, cost and ease of installation. These benefits, the
market acceptance, and possibility to support, more or less, any non-real-time critical protocol,
makes Ethernet an ideal networking technology for most systems.
The media for Ethernet is a dual, twisted-pair, non-shielded copper wire. Industrial wiring well-
shielded cables is highly recommended. A standard Ethernet installation uses a bit rate of 10
Mbit/sec.
A standard 10BASE-T network allows a maximum length of 100 meters. Since every cable is a
separate segment, only two nodes per segment are possible. Repeaters, hubs, routers, and
switches are used to connect the individual segments to larger networks.
Ethernet only specifies the lower layers in the network, so additional protocols like Ethernet
TCP/IP together with Modbus/TCP is needed to form an environment that is easier to use. The
Modbus protocol in the module conforms to the Modbus/TCP specification 1.0.
