Industrial ethernet switches are used to connect Ethernet devices: data frames sent by a device are first received, and then these frames are forwarded to the appropriate switch ports connected to other Ethernet devices. As it transmits these frames, it learns and grasps the location of Ethernet devices and uses this information to decide which ports to use to transmit frames, which helps reduce network occupancy.
What kind of Industrial Ethernet switch is best for your plant’s current application? This is indeed a troubling thing because there are many factors to consider, such as the working environment, whether redundancy is required, managed and unmanaged, future maintenance and scalability, and so on.
Selection of Industrial Ethernet Switches
1. Consideration of working environment: including temperature range, EMC electromagnetic compatibility, protection level, installation method, power supply, etc. Industrial Ethernet switches are designed for domains that are not suitable for commercial switches, such as those with extreme temperatures, high vibration, and strong electromagnetic noise.
2. Choose a managed or unmanaged switch: if the network is relatively simple, you can choose a plug-and-play unmanaged switch; if it is convenient for future maintenance, you may need to choose a managed switch. Only a managed switch can achieve a ring type—topological connections.
3. It is also necessary to meet relevant industrial standards: for example, marine switches should meet the standards of ship structure; if it is used in hazardous occasions, it must meet the corresponding certification standards; rail transit and highways, and other transportation industries also have their own standards.
Electromagnetic compatibility (EMC) refers to the ability of a device or system to operate compliantly in its electromagnetic environment without causing intolerable electromagnetic interference to any equipment in its environment. Therefore, EMC includes two requirements: on the one hand, it means that the electromagnetic interference generated by the equipment to the environment in the normal operation process cannot exceed a certain limit; or degree of immunity, ie electromagnetic susceptibility.
Managed and Unmanaged
The task of a managed switch is to keep all network resources in good condition. The network management switch products provide various network management methods based on the terminal control port (Console), based on the Web page, and supporting Telnet to log in to the network remotely.
Managed switches also have some advanced features that improve your network control. Features like Quality of Service (QoS), Virtual Local Area Network (VLAN), Port Mirroring, IGMP Snooping, Redundancy, and SNMP are usually only available on managed switches, and most managed switches have advanced features.
The above are some tips for choosing an industrial switch. If you need an industrial switch, welcome to consult.
