Siemens 6FC5371-0AA10-0AA2 SINUMERIK 840D sl NCU 710.2 CNC Control Unit with PLC 317-2 DP
Product Description
6FC5371-0AA10-0AA2 is a SINUMERIK 840D sl NCU 710.2 with an integrated PLC 317-2 DP. It is the entry NCU 7x0.2 performance tier and uses PROFIBUS-based PLC integration.
NCU 710.2 is the lower performance tier of the 7x0.2 family, so expansion and axis demand must remain within its documented system limits. Reconnect PROFIBUS and DRIVE-CLiQ by recorded topology and confirm component recognition before any controlled axis test.

FAQ
Which order-code checks belong to the NCU 710.2 System Configuration decision for 6FC5371-0AA10-0AA2?
Match the complete order code, hardware revision, order identity and installed system configuration; a similar family name is not enough for replacement selection.
What must be backed up before the Series Startup Archive procedure for 6FC5371-0AA10-0AA2?
Save the editable application, hardware configuration, communication parameters, retained production data and the firmware or software baseline used by this SINUMERIK 840D sl NCU 710.2 CNC Control Unit with PLC 317-2 DP.
How does performance tier affect NCU 710.2 System Configuration for 6FC5371-0AA10-0AA2?
The 710.2 has a lower documented expansion ceiling than NCU 720.2/730.2.
Why does plc network need separate verification during Series Startup Archive for 6FC5371-0AA10-0AA2?
Retain PROFIBUS station addresses, termination and bus topology.
How should 6FC5371-0AA10-0AA2 complete the Series Startup Archive sequence before return to service?
Complete the documented startup sequence, verify diagnostics and communications, test the application under controlled conditions and confirm the applicable machine interlocks.
Which records confirm that 6FC5371-0AA10-0AA2 completed the NCU 710.2 System Configuration review?
Keep the restored configuration, test results, diagnostic status and the final record for drive-cliq so the installed baseline can be reproduced during later maintenance.
CNC, drive and motion enquiries can include numerical-control hardware, drive modules, servo-related components, encoders and operator panels.
These categories can be combined with PLC or HMI requirements when one maintenance project spans several control layers.
