Solution of Industrial Switch In Industrial Automation Application

Industrial automation is the mainstream trend in the development of the global industrial manufacturing industry. A complete automated production line includes PLC, system control software, industrial robots, etc., and these components all require Industrial Switches to be connected through industrial Ethernet to form a unified whole. Industrial Ethernet is an efficient local area network, which is an important part of the modern industrial automation production system. Whether it is sensor data transmission, or production equipment control, etc., Ethernet is required to form a basic control network. This is also one of the important reasons why industrial Ethernet is more and more widely used in automated production.

The so-called industrial switch is generally used in the industrial ethernet, and the Ethernet switch in the field of industrial digital intelligent control is based on the IEEE802.3 standard and is technically compatible with commercial Ethernet. Meanwhile, the material selection, product strength, applicability, real-time, interoperability, reliability, anti-interference and intrinsic safety can meet the needs of industrial sites.

The robot arm and PLC of the smart factory are in a long-term uninterrupted working state, the working environment is harsh, there are many kinds of electrical equipment in the factory, and the surrounding electromagnetic interference is also very large. Although most factory automation control equipment now has a network interface or serial port for data communication with a computer, the serial port device can be converted into a network device and connected to Ethernet through a serial port server, but the use of ordinary commercial switches cannot meet the use of industrial sites. Ordinary switches are designed based on the indoor environment, and the protection level of dustproof and anti-electromagnetic interference is very low, while the factory is a harsh environment with high dust and high electromagnetic interference, and ordinary Ethernet is based on multiplexing conflicts detection (CSMA/CD mechanism), external interference is severe, it is easy to cause network congestion and lead to network paralysis, which requires factory automation systems to use industrial switches to lay out industrial Ethernet communication lines.

Therefore, the reliability and stability of the system have become the key factors for whether the smart factory can work without interruption. More importantly, the smart factory needs to perform short-distance and long-distance transmission of data, which can not only satisfy the internal management of the factory, but also must satisfy the remote management and information upload. In addition, the installation, operation and management of the new system must be as compatible as possible with the original PLC control system, and future upgrades and expansions must also be considered. The Ethernet solution composed of industrial switches not only satisfies the reliability and stability of the system, but also satisfies the short-distance and long-distance transmission of data, and is also suitable for the future expansion of the system.
