The Controller Area Network (CAN) bus system allows for the standard communication between Electronic Control Unit (ECU) devices via a two line data bus
The CAN bus standard is widely used in industrial sectors such as automotive, shipping, industrial automation and robotics. In automotive environments, for example, ECU devices might include the engine control unit, the transmission system, proximity sensors, airbags and even the audio system.
Developed by Bosch in 1986 and standardized in 1993 as ISO 11898, CAN bus alleviates point to point wiring between electronic components. CAN communication is robust to electromagnetic interference and provides centralized error detection for easy diagnosis
CAN bus has two main modes: Raw Socket Protocol (RAW) mode that allows sending and receiving of singular CAN bus messages, and Broadcast Manager (BCM) mode that allows sending and receiving of cyclic CAN bus messages. The CAN standard does not specify how to encode or decode the raw data, hence the creation of higher-level standards such as CANOpen

IOTech's high performance CAN bus device connector supports both the RAW and BCM modes of operation

Support for RAW mode for sending and receiving singular CAN bus messages
Support for BCM mode for sending and receiving cyclic CAN bus messages
Reading and writing either generically to the CAN bus network or to specified devices based on CAN bus identifiers
Support for configuring the cyclic periods in BCM mode
Support for dynamically adding and removing filter subscriptions based on CAN bus identifiers in BCM mode
Support for both the standard 11 bit CAN identifier and extended 29 bit CAN identifier modes
Uses the String data type when sending and receiving the CAN bus messages

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