PLC is not only the control core of CNC machine tools, but also the "CPU" of control systems in the industrial control industry. Although the PLC industry is developing rapidly, the potential safety hazards faced by PLCs cannot be ignored. Most PLCs are directly connected to the Internet without taking any Security measures. There are great security risks, from Stuxnet in 2010, duqu Trojan in 2011, Energetic Bear in 2013, Havex in 2014, and then In 2016, the highly imitation Stuxnet virus-IRONGATE, the virus is better than the other, and it is impossible to prevent it. If the security of the PLC system is not controlled, the PLC system is likely to be invaded by viruses. The lack of security will not only bring major hidden dangers to the PLC itself, it is also very likely to develop into a back door that threatens the company's production network. Therefore, the security of PLC is the first firewall for the entire industrial network.
Gumei PLC products and PLC all-in-one products have taken protective measures from the first step of intrusion. The encryption technology of the product can completely prevent the program from being read and cracked. This time, PLC is designated as a network security special product to enter the compulsory certification list (controller command execution time ≤ 0.08 microseconds). This regulation will improve domestic PLC technology and applications. Industry insiders speculate: "This move will trigger a new round of reshuffle of the PLC market pattern." Many international brands of PLC will be blocked, and the resulting huge market gap will undoubtedly be filled by domestic manufacturers. Gumei Technology Co., Ltd. believes that this regulation will promote the domestic PLC market to a certain extent. Therefore, domestic PLCs need to be continuously improved in terms of quality and technology, so that domestic PLCs can support the entire market. When selecting industrial control products and systems, select PLC or equipment that has been tested and certified by the relevant national management departments and has been certified by the country. Industrial control products have been tested by qualified institutions and found that there are no network security problems.
