Product Information

Product Application

The FANUC A20B-8101-0930 PROFINET mother board mini slot assembly is mainly used for compatible FANUC CNC or industrial control equipment communication applications. It may be required when the original PROFINET board assembly is damaged, unstable, disconnected, or causing network communication faults.

Because this is a board-level communication interface assembly, replacement should be carried out after confirming the original board number, CNC system model, communication configuration, connector layout, and alarm or communication error details.

Quality Control and Testing

For FANUC PROFINET communication boards, careful checking is very important before shipment because board condition may directly affect CNC network communication, fieldbus connection stability, data transfer, machine operation, and system reliability. REACO CNC checks qualified products carefully and can provide real product photos or a test video before delivery when required.

Our goal is to help customers receive reliable FANUC CNC spare parts with clear product information, careful inspection, responsive after-sales support, and practical technical assistance.

Compatibility Confirmation

Before ordering, please confirm that the full board number on your original PCB assembly is A20B-8101-0930. Similar FANUC communication boards may have different interface types, mini slot versions, hardware versions, connector layouts, system compatibility, fieldbus settings, or software requirements.

Please pay special attention to the PROFINET interface description, mini slot version, and included part number 1120025001. If you are not sure whether this FANUC PROFINET mother board assembly is suitable for your machine, please send photos of the original board label, connector side photos, CNC system model, communication configuration, and alarm information. REACO CNC can help check the details before purchase.
