The second step, if the purchase of domestic PLC, how to seamlessly connect with the original system of everything, conversion, synchronous operation?

The domestic PLC replacement process, the way around is the mix and match of domestic and foreign brands, including the seamless integration of different brands of hosts and IO modules… In any case, the essence of the test is the communication ability and performance matching ability of domestic PLC. Brands that can be mixed and matched to the same production line naturally pass the test. Large PLC has open communication capability, supporting Ethernet, Profinet, EtherCAT, CANopen, RS485 and other communication protocols. In the multi-brand integrated system, the IO module of RPC3000 can be used as a Profinet slave station, and the IO module can be easily managed in the original master station.

Of course, each PLC brand is most willing to see the system purchase. For use as a host, we provide four different buses: CE bus, CH bus, CC bus and CR bus. CC bus is used for simple single-machine IO expansion; CH bus is responsible for redundant data synchronization and communication expansion; CE bus is responsible for high-speed IO expansion; CR bus is responsible for the networking communication of different series of products. For different applications, we can flexibly choose cost-effective IO expansion solutions.

In this way, it can replace imported PLC to meet the needs of high-end applications such as nuclear power, metallurgy, subway and so on?

In the actual application scenario, the large PLC adopts the dual rack redundancy system, the CE bus expansion IO module, and the data interaction and monitoring and control of various devices through the redundant CPU and ring network can meet the needs of more high-end applications.

In the process of localization in various industries, the biggest obstacle is not from the gap in product technology, but the inertia of engineers. Whenever there is change, it means new learning. Especially in the PLC hardware wiring installation, PLC programming language, etc., some people are familiar with Siemens, some people are familiar with Schneider, some people are good at Rockwell… For the blue Light PLC, for the engineers who are used to imported PLC, a familiar process is needed.

For example: Do redundant devices need two backplanes?

A: There is a spare space on the same backplane.

For example: What if I don’t know how to use Rampf programming language?

A: The PLC programming software complies with IEC61131-3 international standards and supports six mainstream programming languages such as ST, LD, IL and FBD.

For engineers who want to learn and understand Lampufeng PLC, we have prepared a wealth of online explanation videos, explanation documents, and more importantly, our strong local technical support team can come to your side at any time to solve problems.

In the current large PLC market share of less than 10% of the domestic brand, its existing technology performance can be fully realized localization replacement? There are several domestic brands with core technology that can be used to replace domestic PLC, but we cannot deny that at present, no one can completely surpass several mainstream international PLC giant brands, and no one can completely replace the market position of imported high-end PLC in China. In the process of domestic replacement of large PLC, it is also for some scenes, some level, some demand, and steadily promote the replacement of domestic PLC.

We believe that every step of the PLC localization replacement is based on the independent research and development of components from product design, and every point of the improvement of the PLC localization replacement market is bound to come from the continuous breakthrough of research and development and industrialization capabilities.

This is the third step to replace PLC localization: lower your head, humble learning, research and innovation; Look up, pick up domestic confidence, and forge ahead!
