METSO D200137 high-performance controller module

The Metso D200137 is a critical ACN RT Node (Real-Time Node) or high-performance controller module used in the Metso DNA (now Valmet DNA) Distributed Control System (DCS).

 It is frequently utilized in high-demand environments, such as pulp and paper mills and power plants, where high-speed processing and precise motor control are essential.

1. Introduction

The D200137 serves as a Process Control Station or an Application Control Node (ACN). Its primary role is to execute real-time control logic, handle data acquisition from I/O modules, and manage communication across the process network. 

In many configurations, it is identified as a Servo Drive Module or a Machine Monitoring Node, as it has the processing power required for the complex algorithms used in high-speed machinery and vibration analysis.

2. Technical Parameter Table

The D200137 is often integrated with or succeeded by other nodes in the ACN family:

D200175: Often found as a sub-component or associated interface board for the D200137.

ACN CS: ACN Communication Server used for higher-level data management.

ACN MR: The Master Redundant version of the ACN controller.

ACN RT: The standard Real-Time Node version.

PDP601: The legacy DPU (Distributed Processing Unit) that performs similar functions in older architectures.

4. Application Cases

Pulp & Paper: Precise control of servo motors in paper machine drive systems and coating sections.

Machine Monitoring: Used as a substation for collecting vibration data (accelerometers/velometers) for predictive maintenance.

Energy Production: Managing high-speed logic in biomass-to-energy conversion and turbine protection.

Mining & Minerals: Integrated into the Metso Standard Control System for crushers and mills to optimize material flow and equipment health.

5. Product Advantages and Features

Real-Time Performance: Engineered for ultra-low latency, capable of execution cycles as low as 20ms for demanding control loops.

Extreme Reliability: The "D-series" hardware is built to withstand harsh industrial environments, including high vibration and a wide temperature envelope (-40°C to +70°C).

Advanced Connectivity: Supports modern industrial protocols including PROFIBUS, PROFINET, and Ethernet/IP, ensuring seamless integration with third-party field devices.

High-Precision Servo Control: Provides specialized algorithms for motor position, torque, and speed synchronization, critical for high-speed production lines.

Hot-Swappable Capability: Designed to be replaced with minimal process interruption when used in redundant configurations.
