Metso D201463 high-performance Network Controller / Processor Module

The Metso D201463 is a high-performance Network Controller / Processor Module within the ACN C20 family, specifically designed for the Metso DNA (now Valmet DNA) Distributed Control System (DCS).

It serves as a central hub for data concentration and network management in industrial environments.

1. Introduction

The D201463 (ACN C20) is a robust controller that functions as a Network Master and Data Concentrator.

It is engineered to bridge communication between field-level I/O modules and the supervisory DNA network. By utilizing a 32-bit RISC architecture, it provides deterministic control and high-speed data processing, making it ideal for managing complex I/O clusters (up to 64 nodes) in real-time industrial applications.

5. Product Advantages and Features

Deterministic Communication: Uses the proprietary DNA ACN protocol to ensure that control signals are delivered with millisecond precision, essential for stability.

High Reliability: Features dual ACN fiber ring support, providing automatic failover in less than 50 ms to prevent process interruptions.

Rugged Industrial Design: Built with a solid, vibration-resistant shell that meets IEC 61131-2 standards for industrial automation equipment.

Data Concentration: Simplifies system architecture by aggregating data from dozens of I/O modules into a single network stream for the operator station.

Hot-Swap Compatibility: Designed for maintenance in live systems, allowing for module replacement without shutting down the entire control rack.
