Description

DeltaV™ SQ Controller
The DeltaV™ SQ controller and the DeltaV I/O subsystem
make rapid installation easy.
Introduction
The DeltaV™ SQ controllers provides communication and
control functions and integrate field devices and the other
nodes on the control network. The SX and SQ 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 SQ controller provides all the features and functions
of the M-series controllers including support for CHARM
based Electronic Marshalling.
The control languages executed in the controllers are
described in the control software product data sheet.
Benefits
Scalable Controllers. The SQ controller complements the
SX controller by providing a smaller controller platform at
a reduced price for those small to moderate applications:
„ Speed. The SQ 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 SQ controller supports
1:1 redundancy for increased availability. Redundant SQ
controllers can be upgraded to SX controllers online — robust!
„ Late Changes. You can easily upgrade an SQ controller
to an SX to handle project scope changes late in the
project. Simply replace the SQ with the SX and all existing
configuration, documentation and hardware design remain
the same — forgiving.

Quick Assembly. The S-series hardware has been designed for
speed of project execution. Carriers snap to standard DIN rails
and controllers and S-series I/O snap into position without the
use of retaining screws.
Easy to Use. Controllers are also easy to configure.
Simply connect the SQ to the DeltaV network and Auto-Sense
it from DeltaV Explorer. Add the controller and all its I/O
interfaces to the system database and all components are
automatically addressed and communicating. There are no
dip switches or jumpers to set.
„ Control strategies are developed using IEC-61131
programming techniques: Function Blocks,
Sequential Function Charts and Structured Text.
„ Automatic diagnostic and event reporting
with time stamps applied in the controller.
„ Set control execution to match process dynamics
and controller scheduling adjusts automatically.
„ Reference any parameter by its module name,
regardless of its location in the system.
„ Synchronized system clock for consistent time
based event driven actions across the system.
„ Online expandable I/O carriers allow new cards to be added
online, with autosense capability, for modular system growth.
„ Hardware redundancy is automatically detected with zero
configuration effort.
Field Proven Architecture. The SQ controller is an evolution
of the DeltaV MQ controller. The new design delivers
installation and robustness enhancement while still using
the same processor and OS that has proven itself in the field.
All S-series I/O cards run the latest software enhancements
of corresponding M-series I/O cards and deliver the same
field proven, reliable operation.
Designed for Electronic Marshalling. The SQ controller
have highly distributable I/O capabilities with CHARMs based
Electronic Marshalling. Electronic Marshalling I/O can be
mounted anywhere, facilitating system design and expansion
while reducing overall system footprint over traditional
marshalled I/O Subsystems.

Advanced Controls. The SQ controller supports all the
advanced control features that are expected in a world class
Distributed Control System:
„ Batch Software
„ Model Predictive Control
„ Neural Networks
