Operator Panel Function

The A02B-0323-C231 forms the main section of a compatible machine operator’s panel. It sends physical key inputs to the control, with command processing determined by the machine builder’s PMC ladder and configuration.

Assigned keys may operate modes, cycle commands, manual movement or other machine-specific functions. A printed key symbol does not independently determine its function; the ladder and key assignment must match the machine.

Modular Panel Structure

FANUC lists the A02B-0323-C231 with related components including:

• A02B-0236-C232: Sub Panel A
• A02B-0236-C244: Sub Panel D
• A02B-0333-C250: I/O Link connection unit
• A02B-0236-K170 / K171 / K174: Applicable key-top sets

These are separate parts and are not automatically included with the main panel. Transparent, blank and symbol-English key-top sets are documented for this panel family.

Product Classification

The A02B-0323-C231 may be called a FANUC keyboard or keypad in search results, but its documented classification is a machine operator’s panel main panel.

It is not a complete CNC control, LCD monitor, touch screen, MDI unit, motherboard, PLC or standalone HMI. It works as part of a machine-specific operator station and requires the correct connection hardware and control configuration.

Compatibility Note

FANUC documents this panel in selected Series 30i/31i/32i Model B hardware structures. Compatibility still depends on the operator-panel layout, I/O Link connection, PMC ladder, labeling and machine-tool builder design.

Before ordering, verify:

• Complete number A02B-0323-C231
• Panel revision and label information
• CNC series and complete system number
• Machine manufacturer and model
• Main-panel and sub-panel arrangement
• I/O Link connection-unit number
• Connector, wiring and mounting layout
• Key symbols and key-top configuration
• PMC ladder and key-assignment requirements

Send photographs of the front, rear, labels and connectors if assistance is needed.

Replacement Note

Replacement may be considered for non-responsive or intermittent keys, damaged key surfaces, connector damage or other confirmed faults. Similar symptoms can result from the connection unit, cable, power supply, I/O Link, PMC ladder or machine wiring, so diagnosis is recommended first.
