Doc.Rev. 2.10

Chapter 4

4. CANopen Fieldbus Functionality

The functionality of the Anybus X-gateway CANopen master/slave on the secondary network is de-
fined by the CANopen DS301 Rev. 4.2 specification and DSP302 (part 1-5).

Note

: The first time the module starts up, it starts as a slave on the secondary CANopen network. It can 

be set as master during configuration, see “Enabling Data Exchange” on page 53. This setting can be 
saved in the module so that it will start as a master the next time.

4.1 Supported Fieldbus Services

Communication and parameters in the CANopen protocol are built around objects. There are different 
services available to communicate with the objects and to perform other CANopen tasks like supervis-
ing the network. The following message types and objects are implemented in the Anybus X-gateway 
CANopen:

• NMT (Network Management)

1

 messages configure and initialize the network, as well as monitor 

the network and handle errors. If the module is configured as a slave, startup is performed by a 
master on the network.

• CMT (Configuration Manager)

1

 messages are used for configuration of CANopen devices. This 

primarily involves PDO parameters and mapping of information. If the module is configured as 
a slave, the configuration is performed by a master on the network.

• PDOs (Process Data Objects) are used for I/O communication. There are 128 Receive PDOs 

and 128 Transmit PDOs implemented in the Anybus X-gateway CANopen that each can trans-
fer up to 8 bytes. Supported PDO message types are COS (Change of state), Cyclic Synchronous 
and Acyclic Synchronous.

2

 

• SDOs (Service Data Objects) use asynchronous data transmission and are used to access objects 

without mapping them to an I/O (PDO) connection. Access is provided to all CANopen objects 
in the module and in the network nodes (master mode). The SDO messages are used to configure 
the module and they can transfer more than 8 bytes, which is the upper limit for a PDO. (Expe-
dited Upload/Download Protocol and Segmented Upload/Download Protocol are supported)

• A SYNC (Synchronization Object) is used for synchronizing PDO communication. A master 

can be either a producer or a consumer of the synchronization. A slave can only be a consumer.

• The Heartbeat Mechanism helps a device to monitor the status of another node. The module can 

appear both as heartbeat producer and consumer.

• The Node Guarding Protocol provides active surveillance of a slave by the master. Slaves can be 

configured to expect a node guarding request from the master. 

• An EMCY (Emergency Object) is used for error reporting when a fatal fault has occurred in the 

module itself or in other monitored/supervised modules.

• LSS (Layer Setting Services)

1

. An LSS master can configure baud rate and node ID of all slaves 

that support LSS (i.e. the preconfigured baud rate and node ID of a slave can be changed by a 
master). 

1. Only available when the module is configured as master.
2. The data exchange with the PROFINET network is limited to 512 bytes, affecting the total number of PDOs that can be used in an 

application.
