Introduction

The DeltaV S-Series controllers provide communication and control functions and integrate field devices and the other nodes on the control network. The SX and SD Plus controllers provide a choice to match the controller capacity to the requirements of the process. They also provide new ease of use features that eliminate mounting screws and accelerate cabinet assembly.

Control strategies and system configurations created on earlier DeltaV systems can be used with this controller. The SD Plus Controller provides all the features and functions of the M-Series controllers with the added support for CHARM based Digital Marshalling.

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

Benefits

Scalable controllers. The SD Plus controller complements the SX controller by providing a smaller controller platform at a reduced price for those small to moderate applications:

 Speed. The SD Plus controller supports all the features you’ve come to expect from the DeltaV system: self-addressing, automatic I/O detection. All these features are designed to make your projects execute faster—just plug and play!

 Redundant architecture. The SD Plus controller supports 1:1 redundancy for increased availability. Redundant SD Plus controllers can be upgraded to SX controllers online—robust!

 Late Changes. You can easily upgrade an SD Plus controller to an SX to handle project scope changes late in the project. Simply replace the SD Plus with the SX and all existing configuration, documentation and hardware design remain the same —forgiving.
