There are various types of industrial communication equipment, commonly including Ethernet switches, industrial gateways, wireless communication modules, etc. Among them, Ethernet switches are used to establish local area networks (LANs) or wide area networks (WANs), enabling data transmission and communication between devices. It has high-speed and reliable data transmission capabilities, supporting multiple network protocols and communication methods. Industrial gateways are used to connect different industrial communication protocol conversions, enabling data parsing and forwarding. Industrial gateways usually have the characteristics of high protection level, stable and reliable operation, and are suitable for harsh industrial environments. The wireless communication module is used to achieve wireless data transmission and communication. These modules include Wi Fi modules, Bluetooth modules, etc., which can achieve wireless connection and data transmission between devices.
