CANopen is a protocol suite based on the hardware of the CANbus\cite{canopen}. CANopen is a protocol suite based on the hardware of the CANbus\cite{canspec}.
It is a hardened differential bus and CANbus is a hardened differential serial communications bus and

It also has a 15 bit\cite{crc15} CRC built into the protocol, which can detect a guaranteed six consecutive bit failures. form the node first transmitting a PASSIVE bit that is DOMINANT on the bus}

This makes it a very safe and robust messaging medium to use for safety critical systems. This makes it a very safe and robust messaging medium to use for safety critical systems.
