Industrial Ethernet Protocol Architecture
The Industrial Ethernet protocol structure is as follows:
Physical Layer: The physical layer is the lowest layer of the Industrial Ethernet protocol and is responsible for transmitting the bit stream. Industrial Ethernet uses transmission media such as twisted pair and optical fiber, and adopts different physical layer standards, such as 10BASE-T, 100BASE-TX, 1000BASE-T, and so on.
Data Link Layer: The data link layer is the second layer of the Industrial Ethernet protocol and is responsible for data transmission and error checking. Industrial Ethernet uses frame format for data transmission, and data frames include fields such as destination address, source address, type, data and checksum.
Network Layer: The network layer is the third layer of the Industrial Ethernet protocol and is responsible for routing and addressing data. Industrial Ethernet uses the IP protocol for addressing and routing data, and IP addresses identify devices in the network.
Transport Layer: The transport layer is the fourth layer of the Industrial Ethernet protocol and is responsible for data transmission control. Industrial Ethernet uses the TCP and UDP protocols for transmission control. The TCP protocol provides reliable connection control and the UDP protocol provides connectionless transmission.
Application Layer: The application layer is the uppermost layer of the Industrial Ethernet protocol and is responsible for data processing and applications. Industrial Ethernet application layer includes HTTP protocol, FTP protocol, SMTP protocol, etc., which are used to realize network applications and services. To summarize, the industrial Ethernet protocol structure includes five layers: physical layer, data link layer, network layer, transport layer and application layer, each of which has different functions and tasks and works together to complete data transmission and processing.
Types of Industrial Ethernet Protocols
Industrial Ethernet protocol types mainly include the following:
EtherNet/IP Protocol: EtherNet/IP is an Ethernet-based industrial control protocol developed by Rockwell Automation. It is mainly used in the field of industrial automation and control. It supports CIP (Common Industrial Protocol) and TCP/IP protocols and can interconnect with a wide range of industrial equipment and systems.
Profinet Protocol: Profinet is an Ethernet-based industrial control protocol developed by Siemens. It is mainly used in the field of industrial automation and control. It supports TCP/IP and UDP/IP protocols and can interconnect with a wide range of industrial equipment and systems.
Modbus TCP Protocol: Modbus is an industrial communication protocol developed by Modicon. It is mainly used in the field of industrial automation and control. It supports Modbus communication based on the TCP/IP protocol and can interconnect with a wide range of industrial equipment and systems.
EtherCAT protocol: EtherCAT is an Ethernet-based industrial control protocol developed by Beckhoff. It is mainly used in the field of industrial automation and control. It adopts real-time Ethernet technology, which enables high real-time and high-bandwidth communication and supports the interconnection of a wide range of industrial devices and systems.
CC-Link IE Protocol: CC-Link IE is an Ethernet-based industrial control protocol developed by Mitsubishi Electric. It is mainly used in the field of industrial automation and control, supports TCP/IP and UDP/IP protocols, and can interconnect with a wide range of industrial equipment and systems. In short, there are various types of industrial Ethernet protocols, and all of them have their applicable fields and advantages, so you need to choose the appropriate protocol according to the specific application scenarios and needs.
