  • Load Memory: Supports external memory cards (e.g., SIMATIC Memory Card, 256 MB to 8 GB) for program storage and backup.
  • Retentive Memory: 128 KB (for retaining critical data during power-off, expandable via external memory).

2. Communication Interfaces

• Built-in Interfaces:
  • 1 x MPI/DP interface (MPI: up to 12 Mbit/s; DP: up to 12 Mbit/s, supports Profibus DP V1 for cyclic/acyclic data exchange)
  • 2 x Ethernet/Profinet interfaces (2-port switch, 10/100 Mbit/s, supports Profinet IRT, TCP/IP, and PROFINET CBA for real-time communication)
• Expansion Interface: 1 x IFM (Interface Module) slot for adding optional communication modules (e.g., Profibus DP, Industrial Ethernet) to extend connectivity.

3. Power Supply & Electrical Ratings

• Input Voltage: 24 V DC (tolerance range: 20.4 V DC – 28.8 V DC)
• Power Consumption: Typical 25 W (no external loads connected)
• Backplane Bus Current: Supplies 5 V DC / 4 A to the S7-400 backplane bus for powering connected modules (e.g., I/O, communication modules).

4. Operating Environment

• Temperature Range:
  • Operating: 0 °C – 60 °C (suitable for most industrial on-site conditions)
  • Storage: -25 °C – 70 °C (protects components during transportation and storage)
• Humidity: 5% – 95% (non-condensing, compliant with IEC 61131-2)
• Electromagnetic Compatibility (EMC): Complies with EN 61000-6-2 (industrial immunity) and EN 61000-6-4 (emission), resisting interference from motors, drives, and other industrial equipment.
• Vibration/Shock Resistance:
  • Vibration: 5 Hz – 150 Hz, 0.5 g acceleration (IEC 60068-2-6)
  • Shock: 15 g acceleration (11 ms duration, IEC 60068-2-27)

5. Mechanical Characteristics

• Dimensions (W×H×D): 40 mm × 290 mm × 210 mm (fits S7-400 standard rack slots)
• Mounting Method: Installed in S7-400 backplane racks (e.g., UR1, UR2) via slide-in mounting
• Protection Level: IP20 (front panel; prevents dust and small debris from entering internal components)

Functional Features

1. High Computing Power: Handles large user programs (up to 48 MB code) and high-volume process data, ideal for large-scale systems (e.g., multi-line production plants, complex process control).
2. Redundancy Support: Optional redundancy configuration (with S7-400H components) for mission-critical applications, ensuring zero downtime in case of CPU failure.
3. Real-Time Communication: Profinet IRT (Isochronous Real-Time) support enables deterministic data transmission (cycle times down to 1 ms), critical for synchronized processes (e.g., robotics, motion control).
4. Diagnostic Functions: Built-in self-diagnosis for CPU, memory, and communication interfaces; provides detailed fault codes via LEDs and software, reducing troubleshooting time.
5. Data Security: Supports password protection and access control (via STEP 7/TIA Portal) to prevent unauthorized modification of user programs.
6. Expandability: Compatible with all S7-400 I/O modules (digital/analog), function modules (e.g., FM 458 for motion control), and communication modules, allowing flexible system scaling.

Application Areas

• Large-Scale Industrial Automation: Used in automotive manufacturing (multi-station assembly lines), electronics production (high-precision component placement), and packaging machinery (synchronized multi-axis control).
• Process Industry: Ideal for chemical, petroleum, and pharmaceutical plants requiring complex process control (e.g., batch processing, continuous flow regulation) and high reliability.
• Energy & Utilities: Applied in power generation (thermal, wind, solar) and water treatment plants to control distributed equipment and transmit real-time data to SCADA systems.
• Infrastructure: Used in airport baggage handling systems, logistics warehouses (automated storage/retrieval systems), and smart factories (Industry 4.0) for integrated, data-driven control.
