The Demand of Iron and Steel Industry for Industrial Switch

The iron and steel industry is an important basic industry of China's national economy and an important symbol of the international economic level and comprehensive national strength. The development of iron and steel has a direct impact on its related national defense industry and construction, machinery, shipbuilding, automobile, household appliances and other industries. In order to better cope with the new market challenges, all steel enterprises are actively promoting new models such as information construction and digital transformation.

The production process of the steel industry is continuous and divided into many processes. Each process has its own basic automation system and process control system (PCS). Each process or several processes have a manufacturing execution system (MES). The upper level of MES includes ERP, energy management system (EMS) and integrated production and marketing management system. Therefore, the whole process of iron and steel industry requires many Industrial Switches for communication between computers or systems.

The network switch used in the iron and steel industry must be an industrial switch, which has higher requirements for real-time, reliability, stability, security and environmental adaptability. The industrial switch can work normally under high temperature, strong electromagnetic interference and other harsh environmental conditions.

Some iron and steel enterprises also put forward the following requirements for industrial switches:

1) The switch supports modular configuration. The port module supports hot plug, and can replace equipment components online. The port supports adaptive, automatic crossover, and automatic polarity conversion functions. Support modular configuration of 100M or 1000M optical port, and do not use photoelectric conversion device;

2) The industrial switch supports multiple network topologies and multiple redundancy modes. The network self-healing time is less than 20ms;

3) Support port security policy to prevent unauthorized access from threatening network security. The management of the industrial switch should also be able to support the password protection mechanism.

4) Support the industrial network clock synchronization protocol, and support the SNTP (Simple Network Clock Protocol) function. SNTP can be activated through the Web or SNMP, with a time resolution of 100ns;

5) Network management software (based on SNMP simple network management protocol), IE browser, super terminal and other methods can be used for network management, diagnosis, monitoring and alarm. OPC function is supported to integrate the monitoring of network equipment into the centralized monitoring system.

Our Industrial switch series products are developed in strict accordance with the requirements of industrial specifications. The whole machine is designed with industrial grade components and fanless cooling circuit, reaching a wide operating temperature of - 40 ° C~85 ° C and a protection level of IP40. It provides excellent industrial quality such as vibration resistance, impact resistance, high/low temperature resistance, corrosion resistance, dust prevention, and pulse magnetic field immunity; Integrate various rich protocols such as routing, switching, security, etc., enhance the reliability of network connectivity, and support rich L2~4 network protocols, such as VLAN, QoS, flow control, FRRP, RIP, OSPF, BGP, etc., to ensure efficient network forwarding; The unified operation configuration interface is adopted, which supports two configuration modes: command line and WEB interface. All functions can be quickly deployed through humanized configuration, helping the device to go online quickly.
