Introduction
DeltaV™ SQ controllers provide communication and control functions and integrate with ffeld devices and other nodes on the control network.
The SX and SQ controllers offer the option of matching controller capacity to process requirements. In addition, they offer new ease-of-use features that eliminate mounting screws and speed cabinet assembly.
Control strategies and system configurations created on earlier DeltaV systems can be used with this controller.
The SQ controllers have all the features and functionality of the M-Series controllers,www.ge-drive.com including support for CHARM-based electronic commissioning.
See the control software product data sheet for the control language implemented in the controller.
Advantages
Scalable Controller: The SQ controller complements the SX controller by providing a smaller controller platform at a lower price point for small to medium-sized applications:
Fast: The SQ controller supports all the features you would expect from a DeltaV system: self-addressing, automatic I/O detection. All of these features are designed to
All of these features are designed to make your projects faster – plug and play!
Redundant Architecture: SQ controllers support 1:1 redundancy for increased availability. Redundant SQ controllers can be upgraded to SX controllers online – ruggedized!
Back-end Changes: You can easily upgrade SQ controllers to SX to handle project scope changes later in the project.
Simply replace the SQ controllers with SX controllers, and all existing configurations, documentation, and hardware design will remain intact.
Fast Assembly: S-Series hardware is designed to speed project execution. Brackets snap to standard DIN rails, and controllers and S-Series I/O snap into place without the need for set screws.
Easy to Use: The controller is also easy to connect.
Simply connect the SQ to the DeltaV network and have it auto-detected by DeltaV Explorer.
Add the controller and all its I/O interfaces to the system database and all components are automatically addressed and communicated with. No dip switches or jumpers need to be set.
Field-proven architecture The SQ controller is an evolution of the DeltaV MQ controller.
The new design enhances installation and stability while still utilizing the same field-proven processor and operating system.
All S-Series I/O cards run the latest enhancements to the corresponding M-Series I/O cards and provide the same field-proven, reliable operation.
Designed for electronic tuning, the SQ controllers have highly assignable I/O functions that can be electronically dispatched using CHARMs-based functions.
The electronic dispatch I/Os can be mounted in any position for easy system design and expansion with conventional I/O subsystems.
Advanced Control
The SQ controller supports all the advanced control features expected of a world-class distributed control system:
Batch processing software
Model predictive control
Neural Networks
Product Description The SQ controller executes control logic based on process signals from the I/O subsystem.
The SQ Controller executes control logic based on process signals from the I/O subsystem and provides communication with the rest of the DeltaV control system for operator interaction and data collection.
Each controller node can be installed as a simplex or redundant node. Each controller node can be installed as a stand-alone or redundant node.
Each controller node can be installed as a standalone or redundant node.
The controller is connected to an I/O carrier mounted on the right side of the controller carrier. Up to 8 carriers can be connected to the local bus I/O.
Each carrier has 8 I/O cards for a total of 64 legacy I/O cards. In addition to the 8 local input/output carriers, each controller can be connected to an additional 16 I/O carriers.
Each controller can also communicate with an additional 16 remote I/O units that carry legacy card-based inputs/outputs.
In addition to traditional I/O cards, the local bus supports Feldbus technologies including Foundation Feldbus, Proffbus DP, DeviceNet and AS-i protocols.
The I/O subsystem also supports serial interface cards and Ethernet I/O interfaces.
The SQ controller also supports CHARM and WirelessHART I/O cards.
The CHARM I/O card (CIOC) connects through the controller’s redundant Ethernet ports to provide a highly distributed and flexible I/O solution called an e-solution.
solution. Up to 16 CIOCs can be connected to a single controller, each providing up to 96 individually controllable signal types.
SQ controller capacity limits may vary depending on the specific application, number of CHARM I/O signals, and control performance requirements.
Enhanced Memory Handling and Hardware Alarms, Indexed to Cover Capacity and Memory
Enhanced memory handling and hardware alarms covering capacity and memory have been added to the SQ controller’s diagnostic information through indexing.
The WirelessHART I/O Card (WIOC) provides redundant communications for up to 100 WirelessHART devices, ensuring high availability and reliability of wireless data.
Up to 16 WirelessHART I/O cards can be connected to a single controller, each providing up to 100 signals.
The controller automatically schedules control modules based on the assigned scan rate. This allows each control function to be dynamically optimized for the process.
Module scan times can be set as fast as 100 milliseconds and as slow as 60 seconds.
The number of control modules that can be assigned to the controller depends on the complexity and scan rate of each module, as well as the available CPU and memory.
The SQ controller is suitable for small to medium sized applications with up to 750 independent I/O signals.
Designed for harsh environments, the SQ controller is rated for G3 corrosive environments and has an operating temperature range of -40 to 70°C. It is ideal for use close to process equipment.
It is ideal for remote installations close to process equipment. For traditional installations using a central dispatch cabinet, the CHARM I/O card can be installed in a standard I/O cabinet that provides electronic dispatch capabilities.
The CHARM I/O card can also be used in highly distributed I/O applications.
