CANopen Protocol Stacks

CANopen® is an open layer-7 protocol based on CAN (Controller Area Network). CANopen® is mainly applied in machines as embedded network system. Moreover, it is used as a general industrial communication system with a data transfer rate of up to 1 Mbit/s.


MicroControl's modular CANopen® protocol stacks are used throughout the world by numerous companies. They have particularly been designed to combine low storage requirements with an optimum performance. By simply exchanging the CAN driver (CANpie) all protocol stacks can easily be adopted to a target hardware. For different requirements we offer the following solutions:


Our CANopen master protocol stack is ideally suitable for complex control systems and offers the functionality of the CANopen® standards CiA 301, CiA 302 and CiA 305.


Our CANopen slave protocol stack facilitates development of intelligent sensors and actuators according to CANopen® specification CiA 301.


Our CANopen bootloader protocol stack can be used to develop a bootloader for flashing sensors and actuators with CAN interface.


As a supplement to our protocol stacks we provide CANopen workshops, software tools as well as technical advice and support in the development of your individual CANopen devices.
