Unlike office and home ethernet, which has been well known for a long time, industrial ethernet needs more professional knowledge and practical experience. If you're installing or using an industrial ethernet, you need to know five things about wiring, signal quality, grounding circuits, switches and communications.
Like all networks, the advantages and disadvantages of cable directly affect the advantages and disadvantages of industrial ethernet. In addition to high electromagnetic interference (EMI), industrial environment often has a certain level of temperature, dust, humidity and other factors that are not common in the home and office environment.
So, how to choose cable? In the office, commercial grade cables, such as category 5 cables, are more suitable for 10MB network, while 5E type cables are suitable for 100MB network. According to ANSI/TIA-1005 standard, 6 types of cables or better cables can be used to connect mainframes or equipment in industrial environments. Six types of cables can realize 1GB network using in the range of 100 meters and 10GB network using in the range of 55 meters. The 6e type cable can realize 10GB network using within 100 meters.
Simply saying, do not use hubs in industrial ethernet environments. Hub is just a multi-port repeater. If hubs are excluded, the only options left are managed switches
and non-managed switches. A managed switch is better, and of course its price is more expensive than a non-managed switch.
UNIPOE provides managed switches. Welcome to buy them.
