As the industrial manufacturing field has fully entered the stage of digitalization and intelligent upgrading, the global manufacturing market has a rapid increase in the application demand for cutting-edge technological achievements. Especially in recent years, PLC (programmable logic controller), known as the “brain” of the industry, has become more and more important in industrial production, transportation, energy management and other fields.

Limited by the lack of technology accumulation, China’s PLC industry started slowly, according to the relevant data show that the domestic large PLC system technology and market are tightly blocked and highly monopolized by foreign manufacturers, there is a large domestic alternative space, while accompanied by the progress of domestic technology and “independent and controllable” related policies under the catalysis of domestic alternative is expected to accelerate.

Central control technology is a leader in the field of domestic process industrial control, starting from the independent research and development of distributed control system (DCS), has been ranked first in the domestic DCS market share for 12 consecutive years, especially in the petrochemical industry has been widely praised. As we all know, the petrochemical industry on product safety, reliability and anti-interference requirements are very strict, market access and technical threshold is very high, and control technology PLC products perfectly inherited its DCS high reliability and continuous stable operation of the excellent gene, which makes it in large-scale infrastructure and important equipment applications have a relatively obvious competitive advantage.

In fact, Zhongcontrol Technology began to lay out the PLC circuit as early as 2005, launched the first PLC product, so far has formed a full range of products for medium and large, large, distributed, cloud deployment and other application requirements, including G5, G3, Fastrol, CloudPLC and other series. It is mainly used in large-scale device control occasions based on process industry, as well as major equipment and municipal fields.
Central control G5Pro
Among them, G5Pro is a fully redundant medium and large high reliability PLC system launched by central control technology, which has a strong core competitiveness in the market. The system ensures the reliability and availability of field applications through the design idea of full hardware redundancy and up to 90% diagnostic coverage. The system has flexible network architecture, powerful remote maintenance ability and extremely high environmental adaptation performance, fully autonomous controllable hardware and software and chips, support Achilles, isoguarantee 2.0, and adopt unified UCP communication protocol to achieve seamless compatibility of data interaction among GCS series control systems.
At the same time, on the basis of G5Pro also derived in line with the SIL3 level of Safety system G5Pro Safety, the core feature is to meet the single card SIL3 capability on the basis of supporting 1:1 thermal redundancy technology, when a controller fails, it can still maintain the SIL3 safety capability is not degraded, to ensure the absolute safety of the scene. The system also supports integrated and mixed deployment of security and non-security, greatly reducing the space requirements and cost requirements for a single control equipment body.
Central control G5Pro Safety

In addition, the G5Pro system has reached 100% domestic version, based on the Loongson 2K series chip as the main core chip, all the IO modules in the system are controlled by the SoC chip from the mainstream chip, which not only solves the localization and autonomous control of the IO module chip. Also provides a large PLC core baseboard 128M high-speed bus encryption communication protocol ECI. At present, G5Pro has been widely used in oil and gas pipeline, rail transit, heating pipe network, sewage treatment, intelligent water supply, traffic tunnel, integrated pipeline corridor, nuclear power, equipment and other industries.

G3Smart is also a very representative PLC product in central control technology. It is a medium-small and highly reliable PLC, which can meet the requirements of high-density and distributed applications. In a narrow installation environment, G3Smart can realize small-point single-machine control, and can also be used as a remote IO module of G5Pro controller for remote expansion. It has been widely used in petrochemical, fine chemical, coal chemical, oil and gas exploitation, municipal engineering, metallurgy, pharmaceutical and other industries.
Central control G3Smart

In recent years, the country has been advocating the direction of development, central control technology early trusted technology and built-in safety technology into the PLC, and obtained the Achilles II certificate. The relevant person in charge of the PLC business said that under the general trend of digitalization and intelligence, the management boundary and business boundary of the control object are gradually blurred, and the user is no longer satisfied with the use of a single automation technology to solve a single specific problem, but requires the integration of management and control, security integration and other complex needs. The trend of integration of PLC, DCS and SCADA is inevitable. The central control technology PLC was originally applied to the process industry as the core of the business extension, and the integration of traditional DCS and SCADA has inherent advantages.

At the same time, Zhongcontrol technology is also continuously investing in research and development, continuously improving product design, and is committed to improving information security, functional safety and high environmental adaptability to meet customer application requirements in the field of major equipment and utilities. In addition, it also innovatively realizes the capability of cloud deployment and multi-level control, providing support for smart factory collaborative management control and artificial intelligence technology based on control optimization.

Under the guidance of relevant policies such as “Made in China 2025”, it is believed that soon, PLC is expected to use the continuous development of cloud computing, artificial intelligence and other new generation technologies, give full play to its own advantages, open new application space, adapt to more complex and changeable market changes and user needs, and lead the continuous progress and development of China’s industrial automation technology
