Introduction

The MX Controller serves as a bridge, facilitating communication and control between field devices and other nodes within the control network. Compatible with control strategies and system configurations from earlier DeltaV™ systems, this advanced controller enhances and expands upon the capabilities of the MD Plus Controller, offering twice the capacity. Detailed descriptions of the control languages executed by these controllers are available in the Control Software Suite product data sheet.
