Siemens S7 series PLC

Today, let's talk about the PLC project that Longzhong is good at
Programmable Logic Controller,PLC. It is a digital electronic device with a microprocessor, a digital logic controller for automatic control, and can load control instructions into the memory for storage and execution at any time. What I'm going to introduce today is──Siemens series PLC

Siemens S7 series PLC is small in size, fast in speed, standardized, with network communication capability, stronger function 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).

Longzhong SIEMENS S7-200 PLC

SIEMENS S7-200 PLC
It is an ultra-miniaturized PLC, which is suitable for automatic detection, monitoring and control in all walks of life and various occasions. The powerful functions of S7-200 PLC enable it to realize complex control functions whether it is running on a single machine or connected to a network. There are 4 different basic models and 8 CPUs to choose from.

 

Longzhong SIEMENS S7-300 PLC

SIEMENS S7-300 PLC
It is a modular small PLC system, which can meet the application of medium performance requirements. Various individual modules can be widely combined to form systems with different requirements. Compared with the S7-200 PLC, the S7-300 PLC adopts a modular structure and has a high-speed (0.6~0.1μs) instruction operation speed; more complex arithmetic operations are effectively implemented with floating-point number operations; a Software tools with standard user interface allow users to assign parameters to all modules; convenient human-machine interface services have been integrated into the S7-300 operating system, greatly reducing the programming requirements for human-machine dialogue.

Longzhong SIEMENS S7-400 PLC

SIEMENS S7-400 PLC
It is a programmable controller for medium and high-end performance range. It adopts a modular fanless design, which is reliable and durable. At the same time, it can choose a variety of CPU levels (functions are gradually upgraded), and it is equipped with a variety of templates for general functions, which enables users to combine different special systems according to their needs. When the scale of the control system is expanded or upgraded, as long as some templates are appropriately added, the system can be upgraded and fully meet the needs.
