Product Description

The SIEMENS Central Control Module, or CPU, is the central intelligence of the SIMATIC system. It houses the processor, working memory, and real-time operating system necessary to execute the entire control program.

Its core function is to operate in a continuous loop: reading the current status of all inputs, executing the user-defined control logic based on this data, performing necessary calculations (e.g., PID control, motion profiles), and subsequently updating the status of all output devices. It also handles essential background tasks, including communication management, system diagnostics, and managing the cyclical data exchange with all connected I/O, both local and decentralized. Modern versions typically integrate high-performance communication ports and specific technology functions (like motion control) directly into the hardware.

Product Parameters

General functional parameters for the Central Control Module (CPU) include:

• Processor Performance: The speed at which the core logic is processed, benchmarked by the execution time per instruction (e.g., $text{ns}$ per $text{bit}$ instruction).

• Memory Architecture: The capacity and type of internal memory, encompassing Work Memory (for execution), Load Memory (for persistent storage, often on a memory card), and Retain Memory (for data preserved during power loss).

• I/O Management: The maximum number of local and networked (decentralized) Input/Output points the CPU can manage and refresh within its cycle time.

• Integrated Interfaces: The quantity and type of built-in communication ports (e.g., dedicated PROFINET ports, Ethernet ports, serial ports).

• Technology Functions: Built-in capabilities such as integrated axes for Motion Control, PID control blocks, and integrated diagnostics capabilities.

• Operating System Features: Support for real-time operation, multitasking, and handling of time-critical interrupts.

• Security Functions: Integrated mechanisms for access protection, programming security, and integrity checking.

Product Advantages

1. High-Speed Control: Offers powerful processors designed to handle complex control programs and fast response times necessary for modern, high-speed machinery.

2. System Integration: Acts as the central hub, integrating various components (I/O, drives, HMIs) through integrated industrial communication standards (e.g., PROFINET), minimizing system complexity.

3. Scalability and Range: CPUs are available in a comprehensive performance range, allowing engineers to perfectly match the computing power to the specific application requirements, ensuring optimized system costs.

4. Diagnostics and Maintenance: Provides extensive system and module diagnostics directly accessible via the engineering software, significantly speeding up troubleshooting and reducing downtime.

5. Future-Proof Engineering: Utilizing the unified engineering environment (TIA Portal) ensures a consistent platform for programming, configuration, and commissioning across all modern SIEMENS control systems.

Notes (Important Considerations)

• Performance Matching: Choosing the correct CPU involves matching its memory capacity and speed to the application’s complexity, the size of the program, and the required control cycle time.

• Licensing and Software: Requires the purchase and use of the appropriate version of the TIA Portal engineering software for configuration and programming.

• Firmware Management: The CPU’s operating firmware must be maintained and occasionally updated to ensure compatibility with new modules, features, and security patches.

• Data Persistence: The amount of data requiring non-volatile storage must be accounted for in the Retain Memory specification.

• High Availability: For mission-critical applications, specific high-availability (redundant) CPU types must be used, which require special configuration and installation procedures.

Product Applications

Central Control Modules are the central components in automated control systems across all industries:

• Complex Machine Control: Coordinating motion, sequencing, and safety logic for robotics, CNC machines, and printing presses.

• Process Automation: Managing large-scale continuous processes such as oil refining, chemical production, and large boiler control.

• Factory and Logistics Automation: Central management of entire production lines, automated storage systems, and material flow control.

• Safety and Security: Executing safety-related logic (when using a Safety CPU variant) and managing industrial control system security.
