CANopen
CAN is a serial bus system especially suited for networking "intelligent" devices as well as sensors and
actuators within a system or sub-system.
CAN is a serial bus system with multi-master capabilities, that is, all CAN nodes are able to transmit
data and several CAN nodes can request the bus simultaneously. In CAN networks there is no
addressing of subscribers or stations in the conventional sense, but instead, prioritized messages are
transmitted. A transmitter sends a message to all CAN nodes (broadcasting). Each node decide on the
basis of the identifier received whether it should process the message or not. The identifier also
determines the priority that the message enjoys in competition for bus access.
