DeviceNet™ System/CAN Description

DeviceNet™ is a low-cost communications protocol that eliminates hard wiring and connects industrial devices such as limit switches, photoelectric sensors, valve manifolds, motor starters, process sensors, bar code readers, variable frequency drives, panel displays and operator interfaces to a network. DeviceNet’s direct connection provides improved communication between devices, as well as important device-level diagnostics not easily accessible or available through hard-wired I/O interfaces.

DeviceNet™ is based on the Controller Area Network (CAN) broadcast-oriented communication architecture. CAN uses a bus arbitration method (CSMA/BA) that ensures the highest priority message is given preference in the event of a data collision. The DeviceNet™ protocol further defines message priorities such that I/O messages are given top priority and configuration messages have lower priority.

A DeviceNet™ network supports up to 64 nodes and virtually an unlimited amount of I/O. The bus uses a trunkline/dropline topology, where bus power and communication are supplied on a single cable. Bus power is 24 VDC and supplies current to operate the nodes and, typically, the power input devices. Some Turck stations require an additional 24 VDC auxiliary power to supply current for outputs.

DeviceNet™ allows peer-to-peer data exchange (where a DeviceNet™ node can initiate communication with other nodes or peers), and a master/slave configuration in which the master node initiates all communication and all other nodes, or slaves, respond to the master node’s requests.


We offer a complete line of molded DeviceNet™ cordsets to facilitate network installation, resulting in a faster start-up and fewer wiring errors. The bus and drop cables are specially designed foil-shielded, high-flex cables with very low inductance and capacitance to minimize propagation delay time. In most cases, bus cable connections are made using 5-pin 7/82 or M12 connectors. A variety of stations are also available that support terminal-block type connections. TURCK cordsets for the DeviceNet system are available in standard lengths.

Network Power

The DeviceNet power may be provided by single or multiple power supply units. The nominal voltage and current rating of all power supply units are: 24VDC +/- 1%, up to 16A continuous feed. The output has to be isolated from AC and a chassis ground. It should be protected against over voltage or over current. The power supply units have a rise time less than 250ms to reach 5% of its rated output voltage. When multiple power supply units are used in an application, V+ is broken between them and only one is grounded.
