1. Introduction

The CAN (Controller Area Network) is a serial communication protocol, which

efficiently supports distributed real-time control with a very high level of security.

It is an especially suited for networking “intelligent” devices as well as sensors

and actuators within a system or sub-system. In CAN networks, there is no

addressing of subscribers or stations in the conventional sense, but instead,

prioritized messages are transmitted. CANopen is one kind of the network

protocols based on the CAN bus and mainly used for machine control network,

such as textile machinery, printing machines, injection molding machinery, or

packaging machines, etc. CANopen is a low level network that provides

connections between simple industrial devices (sensors, actuators) and

higher-level devices (controllers), as shown in Figure 1.1.
