Industrial Ethernet is a communication protocol built on Ethernet technology for industrial automation network communication. It adopts some special technologies, such as multiple paths, high reliability and real-time, to meet the needs of high-speed data exchange and real-time control in industrial production environments.
Industrial Ethernet is a network technology widely used in industrial environments with the following characteristics:
1. High reliability: Industrial Ethernet supports redundancy technology, including link redundancy, ring network redundancy, device redundancy, etc., which can improve the reliability of the network and avoid single point of failure.
2. Real-time: Industrial Ethernet supports real-time communication technologies, such as time synchronization protocols and media access control protocols, to ensure the accuracy and timeliness of real-time data transmission.
3. High bandwidth: Industrial Ethernet has high bandwidth and supports various transmission rates, which meets the needs of industrial production data transmission.
4. Security: Industrial Ethernet supports a variety of security technologies, such as authentication, encryption, access control, data integrity verification, etc., to ensure the security and confidentiality of the network.
5. Scalability: Industrial Ethernet can be easily expanded and upgraded, supporting a variety of topologies, such as star, ring, bus, etc., to adapt to different industrial environments.
Industrial Ethernet has the following advantages over other industrial networks:
1. High-speed transmission: Industrial Ethernet uses standard Ethernet technology, which can realize high-speed transmission of 10Mbps, 100Mbps or 1000Mbps.
2. Large bandwidth: Industrial Ethernet can support relatively high bandwidth and can handle multiple data streams at the same time.
3. Flexibility: Industrial Ethernet supports a variety of connection methods, including point-to-point, star, ring and bus topologies.
4. Easy to manage: Industrial Ethernet is a standardized network that can be easily integrated and managed.
5. Security: Industrial Ethernet supports a variety of security protocols and technologies to ensure data security and integrity.
6. Reliability: Industrial Ethernet's multi-level redundancy technology ensures that the network continues to function properly in the event of a single point of failure.
7. Low cost: Industrial Ethernet uses standard Ethernet technology and requires relatively low-cost hardware components, making it suitable for small and medium-sized businesses.
