Description
x📌 FANUC A20B-8100-0440 — PROFIBUS-DP Slave Interface Board
What it is:
The FANUC A20B-8100-0440 is a PROFIBUS-DP Slave interface printed circuit board (PCB) used in FANUC CNC control systems to provide PROFIBUS distributed automation communication. It allows a FANUC controller or expansion subsystem to act as a slave device on a PROFIBUS-DP network.
Key Functions & Features:
-
🔗 PROFIBUS-DP Slave Communications: This board implements the PROFIBUS-DP protocol in slave mode, enabling the control system to exchange data with a PROFIBUS master (such as a PLC or higher-level controller). PROFIBUS-DP is a widely used industrial fieldbus standard for fast, deterministic communication in automation.
-
🤝 Network Integration: Typically used where FANUC controllers are integrated into a larger factory automation system that uses PROFIBUS for distributed I/O, remote device control, or data exchange.
-
🛠️ Modular Expansion Card: Installed as an add-on interface card within the controller’s electronics assembly or expansion slots — it does not replace the main CPU but provides additional network communication capability.
-
🧪 Legacy & Compatibility: Often found on controllers like Series 16i, 18i, and 21i i-Series where modular communication cards are supported.
Typical Use Cases:
-
Distributed Factory Networks: Connects FANUC CNC units as PROFIBUS slaves to a central supervisory controller or PLC.
-
Machine Data Sharing: Allows real-time status, command, and I/O data to be shared over an industrial bus system.
Notes:
-
This part is discontinued by FANUC and typically available through industrial suppliers as new, surplus, or refurbished units.
-
Core exchange and repair options depend on vendor policies.
