BÜS/CAN OPEN-DESIGN

6.1

Definition

The “büS” (Bürkert system bus) is a fieldbus system based on the CAN protocol (Controller Area Network).
It enables Bürkert devices to communicate with each other.

The Control Head Type 8681 büS/CANopen is a device which conforms to the specification (see chapter “6.5”).

6.2

Network principle / Interfaces

Fig. 2:

Network principle

The PC with the Bürkert Communicator can be connected to each free connection in the büS network, for example
to one of the distributors.

The control head can also be connected to the Bürkert-Communicator for individual configuration. This can be done
(depending on the variant) via the M12 plug or via the connection terminal inside the device. In doing so, the control
head must also be supplied with power.

Different connection cables and a plug-in power supply unit as well as a mains adapter are included in a small
equipment case (“USB büS interface Set1” - see chapter “7”). This allows to configure also a single device.
