Distributed Control System (DCS ):
DEAR air separation has been committed to the development and application of control system in air separation plant for many years, especially the Siemens SIMATIC S7-300/400 H system, and has rich practical experience. SIMATIC S7-400®It is designed as a system solution for production and process automation. The main features of S7-400 are: extremely high processing speed, powerful communication performance and excellent CPU resource margin.
Main performance features:
You can easily assemble S7-400 templates into the baseboard.
• The overall CPU processing speed of the whole series increases 3 to 70 times
Double the working memory, up to 20 MB
• Increase the number of timers and counters by 8 times
• Overall doubled communication performance
Maintain compatibility between components and programming tools
Full support for PROFIBUS isotemporal mode
• Support for modifying distributed hardware without downtime
Special Application fields:
Fault tolerant SIMATIC S7-400H PLC
• S7-400H can be used for applications that require fault tolerance.
• S7-400F can be used for fault safety applications.
In addition, fault tolerant S7-400 HF can also be used
• S7-400 CPU can be used as a PC plug-in
PC-based solutions (WinAC slots)
Configuration of SIMATIC S7-400H with I/O switching connection
Reduce Engineering Cost
S7-400 can be used together with the SIMATIC configuration tool for efficient configuration and programming, especially in a wide range of automation solutions with large quantities. For example, advanced language SCL and graphic configuration tools for sequence control, state diagram, and process-oriented.
Reduce production cost
This product can store the data of the whole project, including symbols and instructions of CPU, so it is helpful for convenient overhaul and maintenance. In addition, the diagnosis function of the powerful integrated system can enhance the practicability of the controller and improve its working efficiency. Therefore, the process diagnosis function that can be set is added to analyze process problems accordingly, thus reducing downtime and further promoting production efficiency.
Increase machine cycle rate
Innovative CPU sets new standards in terms of processing speed and communication performance. Because the performance has been greatly enhanced, the new CPU has laid the foundation for shortening the machine cycle rate.
New features
The backup capacity of the new CPU means that new functions can be integrated without increasing hardware investment, such: quality Data processing, convenient diagnosis, integration into MES scheme or through bus system to achieve fast communication.
This product is a system developed, designed and installed by our company. It has advanced economic and technical indicators and stable and reliable performance.
