Appendix G DeviceNet Physical Layer and Media

Adept MV Controller User’s Guide, Rev. B 383

DeviceNet Physical Layer and Media

The DeviceNet physical layer and media specifications are published in the

ODVA manual, chapter 9, volume 1. It describes possible topologies and

components of the physical layer of the DeviceNet.

'$( shows several possible topologies. The DeviceNet specifications also

specify system grounding, mixing of thick and thin cable media, termination, and

power distribution.

The basic topology is the trunkline-dropline topology. This topology uses

separate twisted-pair buses for the distribution of signals and power. The

specifications allow trunklines and droplines made of thick or thin cable. The

baud rate, maximum distance from end-to-end of the network, and cable size are

dependent on each other. See 94%$(.

Figure G-1. Trunklines and Droplines Made of Thick and Thin Cable

DeviceNet allows devices to be powered directly from the bus, and devices can

use the same cable to communicate with other devices on the bus. DeviceNet

nodes are hot-pluggable — you can remove or add components on the bus

without powering down the network.
