Compared with traditonal PLC,sinoplc large PLC

Sinoplc large-scale programmable controller (PLC, cpu modules plc ) Hollysys in summing up the control system design of fifteen years and thousands of sets of project implementation experience based on the launch of application in the field of medium and high performance control products.

Compared with the traditional PLC, LK can be programmable controller with full integration of the advantages of DCS and PLC, the high performance analog processing technology, miniaturization structure design, open, industry standard, universal system platform, small plc make the product not only has the powerful function and excellent performance, but also has higher reliability, better openness and ease of use.

The development of sinoplc large cpu modules plc

In the development process of sinoplc large PLC, Hollysys fully consider the users of the system security, performance, structure, applicability, and interface of the demand expansion, cpu modules plc efforts to build the system has the characteristics of high performance, high reliability, novel design, easy to use, open and flexible, can bring many benefits to the user.

Use sinoplc large PLC, you can not only solutions based on the flexibility to customize the site actual demand, perfect to realize the control target, to reduce operating costs, input module plc improve work efficiency and system redundancy schemes, compact structure, humanized design can to you thought, do you seek, make you relaxed freely, anytime, anywhere enjoying the joy of working!

The system control center, PLC CPU module

The CPU module is the control center of the system, the user will be prepared to complete the program is downloaded to the CPU module, the CPU module after the start of a cycle of user program execution, each cycle should be read into the process information, cpu modules plc  logic calculation, output calculation results, but also the timing or by user set time, high-speed counting, event processing and communication interrupt process.

The powerful LK PLC, is the first large-scale programmable controller, system
implementation experience based on Hollysys company has accumulated fifteen years of research, high-speed counter modules development and engineering control system, in-depth study and absorb the essence of the international similar products, PLC years of intensive and meticulous farming.
