The programmable controller produced by the German Siemens (SIEMENS) company is also widely used in China, and has applications in metallurgy, chemical industry, printing production lines and other fields. Siemens (SIEMENS) PLC products include LOGO, S7-200, S7-300, S7-400, industrial network, HMI human-machine interface, industrial software, etc. Siemens S7 series PLC is small in size, fast in speed and standardized, with network communication capabilities, stronger functions and higher reliability. S7 series PLC products can be divided into micro PLCs (such as S7-200), PLCs with small-scale performance requirements (such as S7-300), and PLCs with medium and high performance requirements (such as S7-400).
SIMATIC S7-300 PLC
S7-300 is a modular small PLC system that can meet the requirements of medium performance applications. A wide range of individual modules can be combined to form systems with different requirements. Compared with S7-200 PLC, S7-300 PLC adopts a modular structure and has a high-speed (0.6 ~ 0.1μs) instruction operation speed; S7-300 PLC can provide communication configuration function through the user interface of programming software Step 7 to make the State is very easy and simple. S7-300 PLC has a variety of different communication interfaces, and connects AS-I bus interface and industrial Ethernet bus system through a variety of communication processors; serial communication processors are used to connect point-to-point communication systems; multipoint interfaces (MPI) is integrated in the CPU and is used to connect programmers, PCs, human-machine interface systems and other SIMATIC S7 / M7 / C7 automation control systems at the same time.
PLC control cabinet
The PLC control cabinet has protection functions such as overload, short circuit and phase loss protection. It has compact structure, stable work and complete functions. It can be combined according to the actual control gauge size, which can realize single cabinet automatic control or multiple cabinets to form a distributed (DSC) control system through industrial Ethernet or industrial fieldbus network. The PLC control cabinet can adapt to industrial automation control occasions of various sizes. Widely used in power, metallurgy, chemical, papermaking, environmental protection and sewage treatment industries.
