General Information

• Manufacturer: Siemens AG
• Product Series: SINUMERIK
• Product Type: HDD Module with Mechanical Support
• Status: Discontinued (Product Cancellation – PM410 lifecycle phase since September 30, 2004)
• Target Systems:
  • SINUMERIK 810D/840D/840Di CNC systems
  • MMC 103 (6FC5210-0DA20-1AA1/0DA20-2AA1/0DA21-2AA1/0DB21-3AA1)
  • PCU 50 (e.g., 6FC5210-0DFxx series)

Hardware Specifications

1. Storage Capacity:
   • 32 MB DRAM for caching and data processing.
   • 10 GB HDD (as inferred from similar 6FC5247-0AF08-2AA0 models designed for PCU 50/70).
2. Interface:
   • ATA-66/100 (Parallel ATA) for high-speed data transfer.
3. Physical Design:
   • Mounting: Integrated with a steel support plate and vibration damper to withstand industrial environments.
   • Dimensions: Approx. 100 mm (W) × 50 mm (H) × 15 mm (D) (compact form factor for CNC cabinets).
   • Weight: ~1.28 kg (including mounting hardware).
4. Compatibility:
   • Requires SINUMERIK Software Version 3.x or later for full functionality.
   • Supports Windows 3.11 (original OS) and Windows XP Embedded (via firmware updates).

Functional Role

1. System Storage:
   • Stores CNC system firmware, PLC programs, and machine configuration parameters.
   • Hosts user-generated G-code programs and production logs.
2. Data Backup/Recovery:
   • Enables cloning of system images via Ghost software (included with MMC 103).
   • Supports manual backup to external PC Cards (e.g., 6FC5247-0AA00-0AA3).
3. Performance:
   • 5400 RPM spindle speed for moderate access times.
   • 2 MB cache buffer to optimize read/write operations.

Environmental Specifications

• Operating Temperature: 5°C to 45°C (41°F to 113°F).
• Storage Temperature: -20°C to 70°C (-4°F to 158°F).
• Vibration Resistance: 5–500 Hz (compliant with ISO 14641-1 for industrial machinery).
• Protection Class: IP20 (dust-protected, indoor use only).

Discontinuation and Alternatives

• Replacement Model: None directly listed; Siemens recommends transitioning to PCU 50.5-C (6FC5210-0DF52-3AA0) with 4 GB SSD and Windows 7 Embedded for modernized storage.
• Legacy Support:
  • Firmware updates are no longer available.
  • Refurbished units may be sourced through authorized resellers, but compatibility with newer CNC systems is limited.

Installation Notes

1. Physical Installation:
   • Requires 拆卸 MMC 103 from the PCU and replacing it with the HDD module.
   • Torque specifications: 1.5 N·m for mounting screws to prevent loosening.
2. Software Configuration:
   • Must be initialized via SINUMERIK Start-up Tools to format the HDD and load the OS.
   • May require reactivation of software licenses after installation.

Important Warnings

• Data Loss Risk: Mechanical HDDs are prone to failure; regular backups are critical.
• Obsolescence: No technical support is available from Siemens. Users are advised to plan system upgrades.

Verification Tips

• Product Authenticity: Check the 6FC5247-0AA36-0AA1 label for the Siemens logo and holographic sticker.
• Compatibility Check: Use the Siemens Product Compatibility Tool to confirm hardware/software alignment.
