Metso D201380 CPU / Processor Module

The Metso D201380 (often identified with the model code MBR) is a high-performance CPU / Processor Module belonging to the ACN (Automation Cloud Node) platform of the Metso DNA (now Valmet DNA) Distributed Control System. 

It is a modern, high-tier controller designed for complex automation tasks and high-speed data processing.

1. Introduction

The D201380 MBR functions as a Master Control Node or Real-Time Node within the Valmet DNA environment. 

It is the "brain" of the control cabinet, responsible for executing control logic, processing I/O data, and communicating with the wider DCS network. 

This module is specifically noted for its high-speed processing capabilities and is typically used in the ACN RT (Real-Time) and ACN MR (Master Redundant) configurations.

3. Related Models

The D201380 is part of the "D201" high-performance series and works alongside:

D201138 (IBC): Interface Bus Controller used for local I/O communication.

D201139 (IPS): Intelligent Power Supply or interface component for the CPU.

D201376: A similar Real-Time (RT) node often used in parallel or different cabinet tiers.

D201134 / D201135: Analog Input and Output modules managed by this processor.

4. Application Cases

Pulp & Paper Processing: Managing high-speed paper machine logic and complex fiber-line control loops.

Power Plant Automation: Coordinating boiler and turbine control where millisecond-level precision and high availability are required.

Mining & Aggregates: Acting as the primary controller for Nordberg Crusher Automation systems, providing real-time monitoring and protection.

Chemical Refining: Executing complex PID and sequence control in hazardous or demanding environments.

5. Product Advantages and Features

High Processing Density: Capable of executing thousands of function blocks in very short scan cycles (10 ms – 20 ms).

Cybersecurity Hardened: Features an industrial-grade operating system designed to meet modern security standards (IEC 62443).

Robust Fanless Design: Uses advanced heat dissipation techniques to avoid mechanical fans, increasing reliability in dusty or vibrating industrial settings.

Master Redundancy: Fully supports 1:1 hot-standby redundancy, allowing for "bumpless" transfer of control in the event of a hardware failure.

Hot-Swap Support: The module can be replaced while the rack is powered (in redundant setups) without stopping the process.
