- 267 mm (Width) × 297 mm (Height) × 82 mm (Depth) (10.51" × 11.69" × 3.22").
- Weight: Approximately 6.0 kg (13.23 lb).
- Mounting: Rack-mounted within the CNC cabinet (conforms to industrial standard DIN rails).
- Protection Class: IP20 (dust-protected, suitable for indoor environments).
- Operating Temperature: 5°C to 45°C (41°F to 113°F).
- Storage Temperature: -20°C to 70°C (-4°F to 158°F).
- Relative Humidity: 10–90% (non-condensing).
- CNC Core Processing:
- Executes G-code programs, interpolates motion paths, and coordinates axis movements.
- HMI Interaction:
- Provides a graphical user interface for operators to input commands, monitor processes, and access diagnostics.
- System Communication:
- Manages data exchange between the PCU, drives (e.g., SINAMICS S120), I/O modules, and external devices.
- Firmware Management:
- Supports software updates and system backups via Ghost imaging (included with the unit).
The 6FC5210-0DF31-2AA0 was phased out in 2016 and replaced by the 6FC5210-0DF31-2AA1, which offers identical specifications but with extended lifecycle support. Users are advised to transition to the newer model or consider modern alternatives like the PCU 50.5-C (6FC5210-0DF52-3AA0) for compatibility with Windows 7 Embedded and higher-performance hardware.
- Software Version Dependency:
- Requires SINUMERIK Software Version 8.6.0.2 or later for full functionality. Earlier versions may require firmware updates or a clean reinstallation of the OS and HMI西门子中国.
- Third-Party Integration:
- Supports custom PLC programs and interfaces with Siemens SIMATIC S7 controllers via PROFIBUS.
As a discontinued product, the 6FC5210-0DF31-2AA0 is primarily sourced through authorized resellers offering refurbished units or surplus stock. Purchasers should verify compatibility with their existing CNC system and ensure access to software licenses and technical support.
For critical applications, Siemens recommends upgrading to the PCU 50.5-C (6FC5210-0DF52-3AA0), which features a 1.8 GHz processor, 4 GB RAM, and Windows 7 Embedded, providing enhanced performance and security.
