CMX-CANopen allows for optimized implementations of CANopen conformant devices. CMX-CANopen was developed to allow for maximum task optimization, especially when used with an RTOS such as CMX-RTX. Even without an RTOS, CMX-CANopen allows adapting the execution priorities of critical tasks making CMX-CANopen one of the best performing CANopen stacks available.

ROM Specifications: 8K - 18K bytes depending upon processor, protocols used and options selected.

The CANopen Solution for Your Embedded Processor
CMX-CANopen has been developed applying the CMX spirit: provide an elegant solution minimizing the resources required and maximizing the performance. After all, if an implementation uses less code it also executes faster! Our developers have the expertise and hands-on experience to satisfy the most stringent real time demands that the embedded community deals with every day. With CMX-CANopen we created a new level of performance and quality for CANopen implementations.

Efficient Implementation
The CANopen Process Data Objects (PDO) allow for a very flexible configuration allowing a single CANbus message to be filled with a combination of variables available in the Object Dictionary (OD) of a node. This PDO mapping process is implemented so efficiently in CMX-CANopen, that in most cases an incoming Receive PDO (RPDO) can be processed right in the CANbus interrupt service routine.

Advanced Task Control
All major tasks performed in CMX-CANopen are controlled from one single module. If CMX-CANopen is not used with an RTOS, the execution of tasks can still be optimized towards an application. In general, tasks can be executed within the CAN interrupt service routine, a timer interrupt service routine or in the background. This even allows processing different PDOs at different priority levels.

Flexibility
When designing multiple CANopen devices that only vary slightly (for example in some Object Dictionary (OD) entries and/or in PDO configuration) it is desirable to only develop and maintain one version of the code. With CMX-CANopen the entire OD and the PDO configuration can be stored in non-volatile memory. As a result, the configuration of a node can be changed drastically just by downloading a configuration file (download via CANopen supported).
