Product Description

The SIEMENS Central Control Module, often referred to as the Central Processing Unit (CPU) in the SIMATIC family, is the heart of any Programmable Logic Controller (PLC) system. It is the component responsible for executing the user program, managing the system’s memory, and controlling communication between input/output (I/O) devices, peripheral components, and higher-level networks (like MES/ERP systems).

These modules are designed for high performance and reliability in industrial environments. They typically feature an integrated operating system, robust architecture, and native support for communication protocols. Their design emphasizes integration into the Totally Integrated Automation (TIA) Portal for unified engineering, diagnostics, and data management.

Product Parameters

The key technical parameters for a Central Control Module generally include:

• Processing Power:
  • Cycle Time/Instruction Execution Speed (defining performance for control tasks).
  • Processor Type and Clock Frequency.
• Memory:
  • Working Memory: For the execution of the user program.
  • Load Memory: For storing the program and project data (often via a Memory Card).
• Communication Interfaces:
  • Number and Type of Ports (e.g., integrated PROFINET/Ethernet, PROFIBUS, Industrial Ethernet).
  • Maximum data transfer rates.
• I/O Capacity:
  • Maximum Number of Connectable Local and Distributed I/O Modules.
  • Maximum Address Space for I/O and Process Images.
• Integrated Technology:
  • Number of Integrated Motion Control Axes (e.g., positioning, speed control).
  • Built-in functions for counting, measuring, and PID control.
• Redundancy/High Availability (for certain models): Support for redundant operation (R/H systems).
• Power Requirements: Input voltage range (e.g., DC 24V).
