Our CANopen Protocol Stack meets the Requirements of Modern Automation Systems.

The SYS TEC CANopen source code implements the complete functionality pursuant to the CiA 301 V4.x draft standard. The CANopen source code supports the fast and standard compliant design of own fully-featured CANopen master or slave devices, including NMT master (Network Management), LSS master (Layer Setting Services) or SDO client. The straightforward, event-oriented signaling up to Application Level attains a high degree of performance. The CANopen source code is prepared for easy integration to operating systems. The well-defined and thoroughly thought-out API allows for an easy use of the CANopen services without diving into details of the implementation. Many example programs, target specific demo projects and the comprehensive documentation assist you step-by-step.
We offer two main source code packages covering the very most part of industrial applications. Additionally, some special features are available as add-on package.

More than just a source code package

When purchasing the CANopen Source, you get more than just a CANopen protocol implementation. One benefit - get the first year of technical support and software maintenance for free! Furthermore, an USB/CAN interface as well a complete set of CANopen configuration and analysis tools come with the source code package. Thus, you get more than just the source code; it's a convenient environment for development, testing and integration of CANopen devices as well as CANopen based applications. The included CANopen source configuration tool provides you with valuable support in creating the object dictionary and corresponding EDS files. The graphical user interface assists you in managing the various configuration settings of the CANopen source code. You are a mouse-click away from exporting the associated object directory as C-source text, which can be incorporated directly into your CANopen project.

Modular, Scalable and Portable

The continuous modularization of the functionalities and implementation in ANSI-C make possible simple porting to different target systems. Also a considerable weight was placed on scalability and performance. Highly optimized memory management and zero-copy implementation prevent unnecessary copying of data. With our CANopen Source you can just as cost-effectively create single-chip solutions and complex, multi-channel master applications. Our CANopen protocol stack was successfully ported, along with a number of microcontrollers, to a DSP.

The CANopen software is organized into individual modules. Some modules can be incorporated into or removed from the project, depending on the required functionality. The modules do not cross-call functions to another module but only functions from subordinate or superordinate modules (as Callback function). There are no cross-references of global variables between the modules. A central software layer, called "CANopen Controlling Module" (CCM), provides a simplified API of the CANopen functions to the application layer and controls the interaction of the individual modules. Furthermore, the hardware specific implementation is clearly decoupled from the CANopen protocol stack, resulting in a minimum effort required for porting to a new target platform.

CANopen Safety Protocol Support

We offer a CiA 304 compliant CANopen Safety Protocol extension that can be used to build own safety applications. A highly optimized version of our CANopen protocol stack was used to implement the firmware of the CANopen Safety Chip CSC01. Discuss with us the opportunities for use our CANopen in your projects.

IEC 61131-3 ready - The CANopen Manager Source Code

The CANopen Manager Source Code provides substantial extended functionality to implement powerful CANopen devices with managing functions compliant to CiA 302 and CiA 405. The integrated Configuration Manager holds the parameter sets of the assigned CANopen slave devices and handles the on-demand configuration of connected nodes during runtime. Furthermore the CANopen Manager Source Code allows for an easy integration to IEC 61131–3 runtime environments and therefore is prepared for development of CiA 405 compliant controllers. SYS TEC also has an own high-efficient IEC 61131–3 PLC runtime system on hand, including the seamless integration of CANopen and Ethernet communication.

No Royalties on Deployed Products

We offer an attractive pricing structure. You get the complete source on every purchase for an economic one-time fee. There are no royalties on your deployed products.

Complementary Services

Along with our source code products we offer a range of value adding services:

• Consulting and task analysis
• Adaptation workshop and source code Introduction
• Support in preparing your device for the CiA CANopen Conformance Test
• Customer-specific training - Knowledge transfer
