The FANUC A16B-3200-0350 is a combined RISC and Data Server option PCB used in compatible FANUC i-Series stand-alone CNC control units.

FANUC parts documentation identifies the exact A16B-3200-0350 board as a RISC + Data Server Board with hardware identification codes 0xF4 and 0xF5. It combines the functionality provided separately by the A16B-3200-0351 RISC board and A16B-3200-0352 Data Server board.

Within a correctly configured CNC system, its two principal functions are:

• Supporting the RISC-based high-precision contour-control function
• Providing the CNC data-server function through ATA storage media

FANUC system documentation associates this combined option with applicable M-series stand-alone control configurations.

The board is commonly found in organic search results under names such as:

• FANUC RISC and Data Server PCB
• FANUC RISC Data Server Board
• FANUC Series 16i RISC Board with Data Server
• FANUC i-Series Option PCB
• FANUC CNC Data Server Processor Board

The most technically accurate primary name is RISC + Data Server Option PCB rather than Main CPU Board or stand-alone processor controller.

It may be suitable for replacing a confirmed faulty option board associated with loss of data-server functionality, failure to recognize the ATA storage device, RISC-related system alarms, high-precision contour-control problems, board-detection errors, or damaged PCB circuitry.

RISC and Data Server Functions

The A16B-3200-0350 combines two different CNC options on one PCB.

RISC functionality

The RISC section supports the high-precision contour-control function in applicable M-series CNC configurations. Its availability and actual performance depend on the CNC software, purchased options, machine parameters, and system hardware.

Data Server functionality

The Data Server section supports the use of ATA storage for CNC data-server operation. It is not a conventional office or network server; it is a dedicated CNC option for handling data within the supported FANUC control architecture.

The required ATA adapter, storage device, cables, CNC software, and option settings must be confirmed separately.

Related FANUC Boards

FANUC documentation distinguishes the following related option PCBs:

• A16B-3200-0350: Combined RISC + Data Server Board
• A16B-3200-0351: RISC Board Only
• A16B-3200-0352: Data Server Board Only

These boards provide different functional combinations and should not be treated as automatically interchangeable.

A later-generation fast version is also listed separately in FANUC parts information:

• A16B-3200-0460: RISC + Fast Data Server Board

The A16B-3200-0460 should not be considered a direct substitute for the A16B-3200-0350 without checking the CNC model, software, option specification, back panel, and storage-interface configuration.

System Compatibility Note

Available FANUC hardware documentation places the A16B-3200-0350 within applicable stand-alone configurations for the Series 16i/160i and 18i/180i platforms.

The combined RISC + Data Server option is identified as an M-series-only function. A separate FANUC Ethernet hardware guide also marks the RISC-equipped Data Server configuration as not available for Series 21i.

Before ordering, please verify:

• Complete FANUC PCB number
• Board revision printed after A16B-3200-0350
• CNC model and series
• Whether the CNC is an M-series configuration
• Stand-alone or LCD-mounted control structure
• Existing main CPU board number
• RISC and Data Server option status
• CNC software series and edition
• ATA storage device and adapter configuration
• Back-panel and slot arrangement
• Existing hardware identification information
• Availability of the original CNC data backup

The board revision and complete CNC configuration should be matched rather than relying on the A16B-3200-0350 base number alone.

Storage and Data Warning

Replacing this board does not automatically restore the original CNC data-server contents.

Depending on the installed system, the following may need to be transferred, restored, or reconfigured:

• ATA storage card
• CNC machining programs
• Data-server parameters
• Ethernet settings
• CNC software options
• High-precision contour-control parameters
• Machine-specific communication settings
• Related cables and ATA adapter
• System software and hardware-option registration

The original storage media and CNC data should be backed up whenever they remain accessible.

Common Use Cases

• FANUC A16B-3200-0350 option-board replacement
• Repair of a failed RISC and Data Server PCB
• Troubleshooting ATA storage detection problems
• Restoration of CNC data-server functionality
• Diagnosis of RISC-related board or system alarms
• Repair of high-precision contour-control option faults
• Rebuilding a compatible FANUC stand-alone control unit
• Preparation of a tested spare option board
