Page 4: Introduction
1 Introduction 1.1 Overview The CAN (Controller Area Network) is a serial communication bus especially suited to interconnect smart devices to build smart systems or sub-system. It efficiently supports distributed real-time control with a very high level of security. In CAN networks, there is no addressing of subscribers or stations in the conventional sense, but instead prioritized messages are transmitted. - Page 5 I-7188XBD-CAN/μPAC-7186EXD-CAN user manual (ver.1.0.3, May/09/2014)
