Siemens NCU710.2 SINUMERIK Numerical Control Unit
A SINUMERIK 840D sl CNC/PLC unit designation documented with 3 MB CNC user memory and 512 KB PLC user memory.
Product Overview
NCU710.2 is a Siemens SINUMERIK 840D sl numerical control unit designation integrating CNC and PLC hardware for the machine-control system. Siemens documentation identifies NCU710.2 generations with the 6FC5371-0AA10 base article family.
The complete suffix remains essential: earlier documentation lists 6FC5371-0AA10-0AA1, while a later spare record exists as 6FC5371-0AA10-0AA2 with PLC 317-2DP and internal cooling. Hardware generation, software, licenses and machine archive must be matched.
Performance
- Executes the CNC and machine PLC functions within the SINUMERIK 840D sl system architecture.
- Provides the documented user-memory class for NC programs and PLC application data.
- Coordinates the operator components, drive system, distributed I/O and machine communications defined by the project.
- Supports service replacement only when hardware suffix, software release and licensed options align.

System Integration
- Record the full 6FC order number, hardware version, CompactFlash or storage media, software and option licenses.
- Back up NC, PLC, drive, HMI and machine data with tools supported by the installed SINUMERIK release.
- Verify compatibility with operator-panel, DRIVE-CLiQ, I/O, PROFIBUS or PROFINET and safety architecture used by the machine.
- Commission under machine-builder procedures and prove axes, limits, interlocks and safety functions before production.
Applications
- SINUMERIK 840D sl machine-tool control
- CNC and PLC service replacement
- Machine control repair and lifecycle planning
- Installed-base hardware and software migration
FAQ
Is NCU710.2 enough information to order a replacement?
No. Use the full 6FC suffix, hardware generation, software, storage media, licenses and machine project to identify the correct execution.
Are the -0AA1 and -0AA2 NCU710.2 executions automatically interchangeable?
No automatic interchange should be assumed; compare PLC generation, firmware, software release, interfaces and Siemens service guidance.
What must be backed up before replacing NCU710.2?
Preserve NC and PLC archives, drives, machine data, HMI settings, tool and user data, licenses and network configuration.
Can NCU710.2 be commissioned from a blank storage card?
The machine-specific software image, licenses and archives must be available and compatible; a blank card alone does not restore the control.
Which connected-system details matter for NCU710.2?
Document operator panels, drives, I/O, fieldbus devices, safety functions, network addresses and every option used by the machine.
What acceptance sequence follows an NCU710.2 exchange?
Verify boot, licensing, PLC state, communications, I/O, axes, feedback, limits, HMI, alarms and the complete machine safety validation.
