15.8.2 DeviceNet
DeviceNet is used for industrial automation, normally for the control of valves, sensors and I/O units and
other automation equipment. The DeviceNet communication link is based on a broadcast-oriented
communications protocol, Controller Area Network (CAN). This protocol has I/O response and high
reliability even for demanding applications, e.g., brake control.
DeviceNet has a user organization, the Open DeviceNet Vendor Association (ODVA) that assists
members in matters concerning DeviceNet. Website: http://www.ODVA.org
The media for the fieldbus is a shielded copper cable composed of one twisted pair and two cables for the
external power supply. The baud rate can be changed between 125k, 250k and 500kbit/s. This can be done
in two different ways. The first is simply by using the DIP switch, second is via SW configuration. There
are several different DeviceNet scanners available on the market, both for PLC systems and for PCs.
