Siemens 6FC5210-0DF31-2AA0 / 6FC5210-0DF33-2AA0 SINUMERIK PCU 50.3 Industrial Computers
Product Description
Both units provide the PC platform used to run SINUMERIK HMI software, connect the operator panel and exchange data with the numerical control. They belong to the same PCU 50.3 generation and use the documented Windows XP PCU base-software environment.
6FC5210-0DF31-2AA0 is the PCU 50.3-C configuration with the CM370 processor class, 1.5 GHz processing and 512 MB memory. It provides the standard computing level within this generation.
6FC5210-0DF33-2AA0 is the PCU 50.3-P configuration with the higher-performance PM760 platform, 2.0 GHz processing and 1024 MB memory. Both 2AA0 orders share the same lifecycle generation, but their processing and memory capacities are not identical.

FAQ
Which performance difference matters between 6FC5210-0DF31-2AA0 and 6FC5210-0DF33-2AA0?
The C order is documented at 1.5 GHz with 512 MB; the P order is 2.0 GHz with 1024 MB.
Why is a PCU 50.3 image not automatically portable between C and P for 6FC5210-0DF31-2AA0 / 6FC5210-0DF33-2AA0?
Hardware class, storage, PCU base software, drivers and licenses must match the target PCU. Create a recovery image for the exact installed order.
What minimum PCU base software is documented for the 2AA0 PCU 50.3 generation for 6FC5210-0DF31-2AA0 / 6FC5210-0DF33-2AA0?
Siemens documents Windows XP PCU basic software V8.0 SP1 or later for the referenced hardware change.
How does the 2011 type-cancellation notice affect spare planning for 6FC5210-0DF31-2AA0 / 6FC5210-0DF33-2AA0?
Both 2AA0 variants should be treated as lifecycle-managed spares with a tested image, license record and migration path.
Which control interface can be missed when Ethernet still works for 6FC5210-0DF31-2AA0 / 6FC5210-0DF33-2AA0?
MPI/DP is a separate control path. Record its hardware, cable and configuration before removing the PCU.
Can 6FC5210-0DF31-2AA0 and 6FC5210-0DF33-2AA0 be reduced to “PCU 50.3” on the purchase order?
No. The complete MLFB distinguishes the C and P performance configurations.
