3RT1926-2CH21 SIEMENS Central control module

Product Description

A central control module is the heart of an industrial automation system. It gathers data from input modules, processes that information based on programmed logic, and transmits commands to output modules to control machines or processes. These modules are built for high-performance, real-time deterministic control, ensuring that industrial operations occur with microsecond precision. They feature high-speed microprocessors, integrated system memory, and built-in communication ports. The architecture is designed to withstand the rigors of industrial environments, including electromagnetic interference and physical vibration.

Product Parameters

The technical capabilities of a central control module are defined by its processing power and its capacity to manage a network of devices:

• Instruction Execution Time: The speed at which the processor handles bit-logic and floating-point operations.

• Memory Capacity: Includes work memory for runtime code execution and load memory for permanent program storage.

• Communication Interfaces: Built-in ports supporting industrial standards like PROFINET, PROFIBUS, or Point-to-Point (PtP) protocols.

• Retentive Memory: The ability to store specific process variables and states in non-volatile memory during a power outage.

• I/O Address Space: The maximum number of digital and analog input/output points the module can manage locally and remotely.

• Operating Temperature: Standard industrial ratings, typically ranging from -25°C to +60°C for cabinet installation.

Product Advantages

• High Processing Performance: Capable of handling complex mathematical algorithms and high-speed motion control tasks without increasing cycle times.

• Integrated Technological Functions: Features built-in capabilities for high-speed counting, pulse-width modulation (PWM), and PID control.

• Seamless Integration: Fully optimized for the TIA (Totally Integrated Automation) Portal, allowing for unified engineering, simulation, and diagnostics.

• Scalable Architecture: A wide range of performance tiers allows users to select a module that fits the specific complexity of their application.

• Enhanced Security: Multi-level password protection and block protection protocols are integrated to safeguard intellectual property and prevent unauthorized access.

Precautions for Use

• Firmware Synchronization: Always ensure the module’s firmware is compatible with the version of the engineering software used for development.

• Memory Card Selection: Use only manufacturer-certified industrial memory cards to ensure system stability and prevent data corruption during write cycles.

• Thermal Management: Adhere to the specified mounting clearances to allow for natural convection cooling and prevent the CPU from throttling.

• Grounding and Shielding: Ensure the mounting rail is correctly grounded and that communication cables use proper shielding to prevent electromagnetic noise from affecting the processor logic.

• Power Supply Stability: Use a stabilized 24V DC power source to protect the sensitive internal microelectronics from voltage spikes or sags.

Product Applications

• Discrete Manufacturing: Controlling high-speed assembly lines, packaging machinery, and automotive production cells.

• Process Automation: Regulating variables such as pressure, temperature, and flow in chemical, pharmaceutical, and water treatment plants.

• Motion Control: Coordinating multi-axis movements for robotic systems and synchronized conveyor belts.

• Infrastructure Management: Overseeing large-scale systems such as building HVAC, tunnel ventilation, and power distribution networks.

• Safety-Critical Systems: Executing fail-safe control logic in environments where human safety or environmental protection is a high priority.
