The most powerful Automation System within SIMATIC

Superb communication capability and integrated interfaces make the SIMATIC
S7-400 process controller ideal for larger tasks such as the coordination of entire systems.
The graded range of CPUs enables scalable performance and the capacity for I/O
periphery is virtually unlimited.
What's more, process controller signal modules can be inserted and removed while the system is live (hot swapping), making it very easy to expand the system or replace modules.

 

SIMATIC S7-400 controllers stand for: Security of investment Important for plant operators: Long-term security of investment. For this reason, Siemens has systematically further developed the SIMATIC S7-400 series. In this way, they ensure that the right controller will always be available for a vast range of automation solutions in the process industry.

 

High performance Due to its high scalability, the SIMATIC S7-400 series offers various safety and availability levels and thus covers all the relevant applications in the process industry.

Advantages at a glance

• High-availability automation
• Fail-safe automation
• Automation with long-term compatibility
• Scalable automation
• Usable in harsh environments

 

Powerful Depending on the particular industrial application, the optimum automation system can be selected based on performance, quantity structure and communication interfaces. From a favorably priced entry for smaller systems in the lower performance range with limited I/O expansion – up to the high-end range for large networked plants with tasks requiring a high degree of computational performance and where an almost unlimited number of signals can be processed. Companies operating plants profit from the SIMATIC S7-400 series over the long term. These automation systems are being continually innovated, and always represent state-of-the-art technology. These innovations include faster signal processing and expansion of the communication links, for instance. As a consequence, the SIMATIC S7-400 series addresses the upper performance range for industries thus representing the ultimate automation system.

 

Fault tolerant Fault-tolerant S7-400H controllers are your insurance against expensive plant downtimes. The cost effectiveness of your plant or system depends directly on the availability of your production, production lines or complete plant sections, and therefore on the automation system used. With SIMATIC S7-400H, Siemens offers a fault-tolerant automation system, which minimizes the probability of a production failure to nearly 0% – therefore playing a decisive role when it comes to achieving maximum productivity. From the CPU412-5H up to the CPU417-5H, you can select the optimum controller to address your requirements. SIMATIC S7-400H ensures reliable operation of your plants and systems – and avoids production

The SIMATIC S7-1500 significantly increases performance with a fast backplane bus, PROFINET interface, and shortest reaction times.

 

SIMATIC S7-1500 – The ultimate plus for productivity and efficiency

The SIMATIC S7-1500 Advanced Controllers convince with their ultimate power that provides maximum performance for medium-sized to high-end machines with high demands on performance, communication, flexibility, and technology functions.

 

Overview of SIMATIC S7-1500 modules

The SIMATIC S7-1500 features a modular design and can be scaled in terms of its functionality.

Different central processing units (CPU types) are available for multiple performance classes. A wide range of signal modules for input and output as well as technology modules for special technological functions, such as counting, and centralized and decentralized communication modules are available to serve as interfaces to the machine or plant. The SIMATIC S7-1500 is approved for protection class IP20 and designed for installation in a control cabinet.

 

Central processing units

The central processing units (CPU) are the heart of the SIMATIC S7-1500. They execute the user program and network the controller with other automation components.

 

Signal modules

The signal modules or I/O modules form the interface between the controller and the process. They can be used in centralized as well as in decentralized configurations.

 

Technology modules

Technology modules (TM) offer hardware-level signal pre-processing for rapid counting, measurement and position registration for a variety of encoders.

 

S7-1500 Central processing units

 

The central processing units (CPUs) are the heart of the SIMATIC S7-1500.
They execute the user program and network the controller with other automation components.

The scope of Controllers ranges from standard and failsafe CPUs for small to midsize requirements, offering compact size designs with integrated inputs and outputs, supplemented with technological functions, all the way up to most demanding high performance applications.
For applications in the field of midrange motion control, technology CPUs support with extended motion control features. Wherever an integration of high level language C/C++ as PLC function or as self-contained application is needed, multifunctional platform CPUs come into play.

 

 

Features and customer benefits

Thanks to numerous innovations, the CPUs of the SIMATIC S7-1500 deliver the ultimate plus in productivity and efficiency. The hardware is extremely compact. Highly integrated, highly versatile components and modules save space in the cabinet and reduce the spare parts inventory overhead.

 

SIMATIC ET 200MP / S7-1500 Signal Modules

The signal modules or I/O modules provide the interface between the controller and the process. The controller detects the current process status by means of the connected sensors and triggers the corresponding actuator reactions.

The digital and analog modules provide exactly the inputs/outputs that are required for the respective task. They can be used both centrally, i.e. directly on the CPU, as well as locally in the ET 200MP I/O system. 25 mm and 35 mm modules are available.

The analog modules possess expanded functions like oversampling, measuring range adjustments or scaling of measured values.
