Comprehensive Devices and Network Analysis for CANopen

CANopen® is an open, CAN-based communication protocol. Its wide range of application includes the areas of transport and control technology, measurement systems, medical technology, railway technology, maritime applications and much more – in short where ever great flexibility and rapid data transmission are in demand. The specification is built on the experience of many component manufacturers and users, resulting in a well-established standard that is maintained by the CAN in Automation (CiA®) user organization.

CANalyzer’s powerful functionality together with the functional expansions for CANopen gives you a tool that can be used both in the development of CANopen systems as well as their startup and maintenance.

CANalyzer .CANopen Option makes high-performance, CANopen-specific functions for analysis and configuration available to the developer. This is a prerequisite for reliable and efficient interaction with CANopen networks.


  • Integrated configuration and analysis tool from a single source
  • Support of commonly used CANopen standards
  • Convenient interpretation of the bus traffic by protocol descriptions and color differentiation of CANopen services
  • Automatic generation of a CAN database using EDS files
  • Abstracted configuration of PDOs by graphically linking process data
  • Easy dialog-based access to CANopen device parameters
  • Logging of the CANopen bus traffic with later offline analysis


CANalyzer .CANopen extends the basic functionality of CANalyzer by adding:

  • Configuration of CANopen devices
  • Interactive access to CANopen devices
  • Interpretation of CANopen messages
  • Interactive generation of CANopen messages
  • Creation and testing of EDS files
  • Protocol-specific representation in the Trace window
  • Protocol monitoring
  • Graphical representation of devices
  • Network management, guarding, heartbeat
  • Setting the baud rate and node ID via Layer Setting Services
  • Use of the CiA standard file formats EDS/DCF

Along with the base tool CANalyzer, CANalyzer .CANopen also contains the ProCANopen configuration tool and the CANeds EDS editor.

Application Areas

CANalyzer's powerful functionality together with the functional expansions for CANopen gives the user a tool that can be used both in the development of CANopen systems as well as their startup and maintenance. CANalyzer.CANopen makes high-performance, CANopen-specific functions for analysis and configuration available to the developer. This is a prerequisite for reliable and efficient interaction with CANopen networks.

Communication Monitoring

Communication monitoring

In a Trace window the CAN message traffic is displayed while simultaneously interpreting the protocol information it contains. The user not only sees the service that is currently being executed, but can also examine all relevant service parameters. This information is displayed in clear text. To simplify analysis, CANopen services are distinguished by different font and background colors. The user gets a quick overview of the chronological order within protocol sequences for the observed CANopen services. This makes it significantly easier to locate errors in a real system.

CANalyzer .CANopen also monitors for the correctness of individual protocol sequences. This involves detecting whether the protocol information was properly entered in the CAN message. To ensure that the described device information is also available in CANalyzer .CANopen, just add a CAN database that is automatically generated in a ProCANopen project. Messages or process data can then be accessed symbolically in CANalyzer .CANopen.



Not only is the Trace window, but also the familiar Data and Statistics windows of the standard version of CANalyzer are available for the analysis of CANopen data. in addition, the CANopen Scanner evaluates CAN messages and shows the active nodes in a list. It displays other node-specific information as well, such as the node state or device name.

CANopen-specific message sequences can be assembled within a dialog. From a project-specific list of existing messages, you select and configure the desired messages (PDOs, SDOs, etc.) and assemble them into a sequence. The sequence can be replayed once or periodically. This means that message sequences can be sent to the connected devices as often as desired.

ProCANopen | CANeds

Included with the product CANalyzer .CANopen is the project planning tool ProCANopen and the EDS editor CANeds.

Project Planning Tool for CANopen Networks

CANopen network design tool ProCANopen

CANalyzer .CANopen contains ProCANopen to enable efficient and quick planning of complete CANopen networks as well as devices. You are supported in all project phases, including planning, development, start-up, and service.

ProCANopen provides the following functions:

  • Graphical representation

  • Configuration of the data communication

  • Interactive access to the object dictionary

  • Download of project data and start-up

Through the extensive functions, combined with an intuitive user interface, you can concentrate immediately on the definition of the system parameters. ProCANopen executes the concrete and CANopen-conforming implementation of projects automatically. This significantly reduces the configuration effort required for extensive systems. The quality of the configuration thus created is increased, which in turn increases security of the system.


The EDS Generator for CANopen Systems

EDS file editor CANeds

The editor/generator CANeds is a tool for creating and testing EDS files. CANeds takes over the difficult and error-prone task of creating EDS files manually. CANeds enables device manufacturers and system integrators to avoid problems when working with corresponding CANopen configuration programs.

CANeds provides the following functions:

  • Creation of new EDS files

  • Modification of EDS files

  • Testing of EDS files

  • Scanning of devices, with EDS files generated semi-automatically

Creating EDS files is very easy due to the ability of accessing standard objects and their attributes via CiA-CODB databases. CANeds displays the structure of an EDS in a hierarchical tree structure and represents CANopen object attributes such as object and data types symbolically.

Technical Article: Overcoming Logging Challenges in ADAS Development Projects

The more tasks that driver assistance systems assume along the way to autonomous driving, the greater the number of

sensors in the vehicle from different suppliers. Real road traffic provides the ideal reference data for testing – in endless

variety. For this purpose, OEMs and system suppliers are sending test vehicles equipped with high-end data loggers onto

the streets to collect data. That data is then used to precisely ”re-simulate“ certain traffic situations in the laboratory

to test new or refined ADAS sensing and control logic. Instead of implementing numerous sensor-specific logging systems,

what is required are scalable approaches and strategies.
