Siemens 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0 SINUMERIK PCU 50.5-C Industrial Computers
Product Description
Both models provide the Celeron-class PCU 50.5 computing platform used by the SINUMERIK operator system. They share the same cabinet-computer role and documented mechanical envelope while hosting the HMI software and machine-specific operating environment.
6FC5210-0DF52-2AA0 is the Windows XP configuration with 1024 MB memory and the corresponding PCU base-software line. It supports installations that remain on the earlier SINUMERIK software environment.
6FC5210-0DF52-3AA0 is the Windows 7 Embedded 64-bit configuration with 4 GB memory. The common hardware family does not make the system images interchangeable because operating system, memory, drivers and application compatibility differ.

FAQ
Can a Windows XP image from 6FC5210-0DF52-2AA0 be restored to 6FC5210-0DF52-3AA0?
No. The latter is the Windows 7 Embedded 64-bit configuration with 4 GB memory; plan application, driver and license migration.
What is the documented memory difference between the two PCU 50.5-C orders for 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0?
The XP 2AA0 configuration has 1024 MB, while the Windows 7 3AA0 configuration has 4 GB.
Why must the Windows 7 PCU be shut down through Operate or Windows for 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0?
Siemens documents a controlled shutdown before power-off to protect the operating system and storage.
Does the common 297 × 267 × 82 mm size make the two orders software-compatible for 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0?
No. Mechanical commonality does not remove the operating-system, memory, driver and application differences.
Which mounting item should be checked in the bill of materials for 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0?
The catalog lists the mounting bracket separately, so confirm it is present and suitable for the enclosure.
What should be tested after an XP-to-Windows 7 migration for 6FC5210-0DF52-2AA0 / 6FC5210-0DF52-3AA0?
Validate SINUMERIK Operate/HMI, control communication, screen path, network services, peripherals and all required licenses.
