2 CANopen system overview
The Beckhoff Embedded PCs can be ordered ex works with an optional interface, e.g. PROFIBUS,
CANopen or RS232. Some of the optional interfaces can be delivered as master or slave.
The following Embedded PCs can be ordered with an optional interface:
• CX9020
• CX50x0
• CX51x0
• CX20x0
CANopen master (M510)
The optional interface M510 is a CANopen master and enables a segment-like construction of control
structures in large plants and machines. Further Beckhoff fieldbus components such as Bus Couplers, Bus
Terminal Controllers, drive components, etc. can be used with an Embedded PC for configuring control
structures.
Fieldbus masters are used for decentralized collection of process data and signals in large machines and
plants. The number of slaves that can be connected to the master is only limited by the respective bus
system. Using master and slave connections makes it possible to link several Embedded PCs with each
other via the fieldbus level.
The optional interfaces are detected, parameterized and configured in TwinCAT, and the connected I/O
components are added. TwinCAT is also used for diagnostics.
CANopen slave (B510)
The optional interface B510 is a CANopen slave and enables an Embedded PC to be used as subordinate
decentral controller for configuring complex or modular systems.
The CANopen slave receives external process data from the master and processes them or returns data
from its own process periphery to the master after processing.
Like the CANopen master, the optional CANopen slave interface is parameterized and configured in
TwinCAT.
Functioning
CANopen is a widely used fieldbus system, which was developed by the CAN in Automation (CiA)
association and in the meantime has been adopted for international standardization.

CANopen consists of the protocol definition (communication objects) and the device profiles.
The protocol definition includes the following communication objects:
• Network Management (NMT)
