CANopen connectivity | IOTech Systems

CANopen builds on top of the Controller Area Network (CAN) communication system to describe a more convenient programming abstraction for the user than regular CAN bus
CANopen defines higher-layer protocols and profile specifications and so greatly simplifies the task of developing and integrating a CAN-based system. In the Open Systems Interconnection (OSI) model, CANopen covers everything from the network layer to the application layer, with CAN providing the data-link and physical layers of the stack
CANopen was originally designed for motion-oriented machine control systems but today is used in various applications, such as medical equipment, off-road vehicles, maritime electronics and railway applications
CANopen provides standardized Communication Objects (COB) for defining data flow and describes advanced protocols for how that should be achieved. Process Data Objects (PDOs) typically describe data that changes frequently such as sensor data, while Service Data Objects (SDOs) describe communication for node-specific and general configuration data

IOTech's high-performance CANopen device connector provides advanced CANopen communication via both SDO and PDO read and write operations

CANopen network management functions including adding, deleting, starting, and stopping nodes
CANopen object management functions including creating and deleting PDOs and SDOs
CANopen communication via SDO and PDO Read and Write operations
Support for accessing CANopen-based events that are created and stored in the event queue
Support for Boolean, Int8, Uint8, Int16, Uint16, Int32, Uint32, Int64, Uint64, Float32, Float64 and String data types
Convenient setup with supplied configurations and ready-to-use resources for the CANopen network and object management functions
Compatible with both conforming CANopen devices and external CAN USB connectors

Note that the CANopen connector interacts with CAN via the Linux SocketCAN driver and therefore is not supported on Windows
