Emerson M-series MD Plus Controller

Introduction

The MD Plus Controller provides communication and control between the field devices and the other nodes on the control network.

Control strategies and system configurations created on earlier DeltaV™ systems can be used with this powerful controller.

The MD Plus Controller provides all the features and functions of the M5 Plus Controller,

with plenty of memory for large batch and other memory-intensive applications.

The control languages executed in the controllers are described in the Configuration Software Suite product data sheet.

Benefits

Increases productivity

Faster. The MD Plus Controller is more than 400% faster than the M5 Plus Controller and over

3X the user configurable memory as the MD controller. The Ethernet ports are full duplex, 100MB/second maximum throughput.

The results are lower CPU utilization and higher capacity for control strategies.

Self-addressing. The DeltaV controller is unique in its ability to automatically identify itself to the DeltaV control network.

When the controller is powered up, it is automatically assigned a unique address—no dip switches, no configuring—just plug and play!

Self-locating. A controller’s physical location is easy to find. LEDs on the face of the controller can be made to flash, providing a strong visual clue.

Automatic I/O detection. The controller can identify all I/O interface channels located on the subsystem.

As soon as an I/O interface is plugged in, the controller knows the general characteristics of the field devices managed by that I/O interface.

This reduces the no value engineering associated with configuration — easy!
