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.
