CANopen® – for Decentralized Use

Nopen® is an open communication profile for the CAN Bus (Controller Area Network)  developed for automotive engineering. In the meantime, CANopen® is used in different  areas like medical technology, maritime, traffic  control, utility vehicles and automation.

General Technical Data

Transmission medium

The connection between individual stations (nodes) is implemented via a hybrid cable for the transmission of data as well as the system and sensor supply.

It comprises two twisted and shielded lead pairs and total sheathing:

“Thick cable” as the master line and/or for the bridging of greater distances.

• “Thin cable” with smaller cable cross sections for stub cables and networks of smaller spatial expansion.

Network topology

Line structure or line structure with stub cables. The main line must be terminated with resistors (120 Ω) on both sides.

Number of devices

127 nodes (including master)

Admissible transmission rates and line lengths

The maximum admissible length of line depends on the Baud rate used and the number of modules.
