2.Basic Concepts of Communication Protocols
Before introducing the communication protocols supported by Mitsubishi bus drivers, we must first understand the fundamental concepts of communication protocols. A communication protocol is a set of rules and conventions ensuring the correct transmission and reception of data during communication. Communication protocols typically encompass the following aspects:
- Physical Layer: Defines the physical devices used in communication, such as cables and connectors.
- Data Link Layer: Defines the basic units of data transmission (e.g., frames) and error detection/correction mechanisms.
- Network Layer: Defines packet routing and forwarding mechanisms.
- Transport Layer: Defines end-to-end data transmission mechanisms, such as the TCP/IP protocol.
- Session Layer, Presentation Layer, and Application Layer: Define the interaction methods between applications.
