1. Scope
The scope of this document is, to define the content of the physical layer and the basic
characteristics of the physical medium, for communication according to the Controller Area
Network protocol specification (CAN) between different types of electronic modules in general
industrial applications. CAN is a serial communication protocol supporting distributed real-time
