Since the development of PLC technology, the development direction is mainly toward  miniaturization, standardization, serialization, intelligence, high speed, large capacity and network has made PLC function stronger and higher reliability. Siemens S7 series PLC Technology fully reflects this direction of development.

Siemens PLC products include LOGO, S7-200, S7-300, S7-400. Industrial network, HMI man-machine interface, industrial software, etc., covering all automation fields. Its PLC products mainly include: SIMATIC mainly includes S7 PLC, M7  Automation computer, C7, SIMATIC NET industrial network, SIMATIC HMI operator interface, DP distributed I/O device, SIMATIC PC and PCS7 process control system.

plc siemens simatic s7-300 siemens simatic s7 400 are our advantages products,our company specializes in selling various industrial automation equipment such as Allen Bradley, GE                FANUC,OMRON,SIEMENS,SCHNEIDER,MITSUBISHI,ARO. ETC.for many years. Please add my email address and contact information to your contact. Maybe you don't have a demand yet, but one more choice, one more way. If you have any needs, I am willing to quote you, or if there are some problems, please send me an email, maybe I can help you. Thank you again for knowing you in this big world!

SIMATIC S7 series programmable logic controllers are divided into mini PLC (such as S7-200), PLC with small-scale performance requirements (such as S7-300) and PLC  with medium and high performance requirements (such as S7-400).  SIMATIC M7 PLC brings the performance of AT-compatible computers to PLC, facing computer users, and bringing the PLC functions into the computer, while keep the user familiar programming environment.

The SIMATIC C7 system is an organic combination of PLC (S7-300) and man-machine operation panel. The HMI human-machine interface series mainly includes text operation panels TD200, OP3, OP7, OP17, etc.; graphic/text operation panel OP27, OP37, etc.; touch screen operation  Panel TP7, TP27-6, TP27-10.TP37, etc.; SIMAT-IC panel type PC670, etc.

The programming and engineering tools include all the tools required for programming, configuration (integration of ProTool), simulation and maintenance based on PLC or PC.  With STEP7, you can select the programming language ladder (LD) and function diagram (FBD) instruction list (IL) programming language and IEC1131 programming language, etc., you can also use the high-level language structure text S7-SCL or the sequential function diagram S7-Graph,  The language uses a very efficient method to graphically describe the sequential control system. The entire engineering system includes advanced system diagnostic capabilities, process diagnostic tools, PLC simulation, remote maintenance and project documentation:

SIMATIC STEP7 is a project management tool for configuration programming and maintenance of SIMATIC S7-300/400, C7PLC and SIMATIC Win AC PC-based control products. STEP7 for Micro/Win is for programming SIMATIC S7-200 series PLC, online  Simulation software.

PC based control software includes PC based solutions instead of traditional PLC to automate user applications or processes. WinAC is a PC based control translated into Windows Automation Center (WinAC). WinAC is integrated with controls running on the same platform.  , HMI, network and data processing integration. The WinAC control section allows the use of a personal computer as a programmable controller (PLC) to run the user's process. WinAC can provide two kind of PLC, one is a software PLC.

It runs as a Windows task on the user's computer. The other is the slot PLC, which has all the functions of the hardware PLC. These PC based engines communicate via PROFIBUS distributed I/O. WinAC calculation/visual part provides  All open interfaces required to navigate through the standard application and modify process data.  These solutions are fully compatible with SIMATIC S7-PLC. In this case, the same configuration data, the same program, the same 1/0 can be used immediately.

The Human Machine Interface (HMI) provides a human-machine interface or SCADA system for user automation projects, supporting a wide range of platforms. ProTool is used for machine-level applications and is suitable for most HMI hardware configurations, from operator panels to standard PCs.  ProTool integrated in the Step7 software can be configured very efficiently.  The Step 7 symbol database is easily accessible from ProTool. The ProTool/lite software is used for the configuration of text displays, like OP3, OP7, OP17, TP17.

These configuration software are easy to development: screen information; alarm system; recipe management; printer interface; connection to PLC.-PTO Tool/Pro software for configuring standard PC, ProTool/Pro also provides other tools for development.  In addition to the features of PToToo/Lite and ProTool, ProTool/Pro offers other tools for development.  The WinCC software is suitable for monitoring applications. WCC is an open HMI SCADA software: it can be run on any PC. WCC fully supports distributed system architecture, it is designed for a wide range of applications and can be connected to existing ones.  In an automated environment, there are a large number of communication interfaces and comprehensive process information and data processing capabilities.
