With the continuous reduction of PLC price and the continuous expansion of user demand, more and more small and medium-sized equipment began to use PLC for control. The application of PLC in China is growing rapidly. With the rapid development of China's economy and the continuous improvement of domestic automation level, PLC in China will continue to maintain the momentum of rapid growth in the future. Today's PLC products can be divided into three schools: the United States, Europe and Japan. With the rapid development of China's PLC, domestic PLC occupies more and more weight. According to statistics, the failure rate of these PLC products is more than 95% in power supply, relay, communication port and other places. So how to reduce the failure rate of these places? Gu Mei made these changes to PLC

External power supply, 90% trouble shooting

To prevent the air, dust, ultraviolet and other factors from damaging the equipment under the influence of air temperature change and humidity change. The most prone to failure is generally in the power system and communication network system. In the continuous work and heat dissipation of power supply, the fluctuation and impact of voltage and current are inevitable. Communication and network are likely to be affected by external interference, and external environment is one of the biggest factors causing external communication equipment failure. At present, PLC in the market is basically built-in power supply, and our products use external power supply to eliminate 90% of the faults.

The relay uses Omron, one of the best brands

The cost control and type selection of PLC depend on I / O module, which is an important part of PLC. The biggest weakness of PLC is I / O port. The technical advantage of PLC lies in its I / O port. In the case that the technical level of host system is different, I / O module is the key component to reflect the performance of PLC, so it is also a prominent link in PLC damage. The relay used by Gu Mei is Omron, one of the top ten brands in the world.

Special protection of communication port

RS-232 interface has low data transmission rate, limited transmission distance and poor anti-interference ability. RS-422 adopts full duplex communication mode and differential transmission mode to enhance the anti-interference ability of common mode. Gu Mei uses 485 port, which has higher pressure resistance than 232 port and is not easy to burn out.

Through these methods, the failure rate of PLC is greatly reduced, and the volume of PLC is smaller, but the performance is better. These applications in customers have always been recognized by customers.
