For industrial Ethernet networks, the most important expense is not the components that build the network, but the parts that are designed, installed, and maintained.

“How do you know if you are looking for hardware or software errors?” When there is a problem with the factory automation system, the first reflection is that the network has failed. In today's industrial automation systems, industrial Ethernet (Ethernet switches) are increasingly used. We need to know the faults in time and accurately, and eliminate them, we must understand the fault classification and maintenance of communication equipment. .
The classification of faults is divided into software faults and hardware faults according to the nature of faults. Soft faults are faults caused by software system errors. Common soft faults include program errors, virus corruption, operational errors, and setup errors and blind operations.
Hard fault refers to the physical damage of the equipment hardware: First, human and environmental reasons, such as poor environment, poor power supply, static electricity damage or violation of operating procedures; second, electrical components, such as components, contact plug-ins, printed circuits, etc. Damage caused.

In the industry, dedicated industrial Ethernet switches are usually used to define different priority levels of the Ethernet frame so that the information desired by the user can be transmitted at the fastest speed. Here are some things to keep in mind when using an IE switch:

(1) Do not place the device near water or in a damp place;
(2) Do not put anything on the power cable, and put it in a place where it cannot be touched;
(3) In order to avoid fire, do not knot or wrap the cable;
(4) The power connector and other device connectors need to be firmly connected, and often check the line's robustness;
(5) Keep the fiber optic socket and plug clean. When the equipment is working, do not look directly at the cross section of the fiber;
(6) Pay attention to the equipment cleaning, if necessary, wipe with cotton cloth;
(7) When the equipment fails, do not repair it yourself for safety reasons.
