BASED ON EMTAS' UNIFORM CAN DRIVER INTERFACE and the universal CAN queue the CAN Multi Protocol Stack from the company supports various CAN based protocols such as CANopen, Energybus, SAE J1939, raw CAN, and proprietary protocols in one application.

The configuration of the CAN Multi Protocol stack is done by the graphical tool CAN Device Designer which is included in the scope of delivery. Based on its profile and signal databases for CANopen, Energybus, and J1939 the user can select the data that shall be transmitted or received and the relevant services. The stack supports all CANopen Master and slave features and J1939 broadcast and transport protocols in order to send larger data packets.

Even raw CAN message und manufacturer-specific protocols based on them are supported. Using the CAN Device Designer application variables can be mapped into CAN messages and the stack handles the transmission and reception automatically. Time triggered or event triggered transmission are supported. On reception of a defined CAN message the application variables are updated automatically by the stack.

The stack is available for a large number of micro controllers (STM32, Kinetis, XMC4000, dsPIC44, Tiva, etc.) and operating systems (Linux, Windows, RTX64, etc.). The CAN Device esigner tool can be used on both Windows and Linux.
