DeltaV System Overview






Fundamental New Architecture

Unlike today’s DCS, PLC, Hybrid, and component solutions, the DeltaVTM system’s unrestricted information flow between intelligent field devices, the DeltaV system, and enterprise resource planning systems gives you a tremendous advantage in ease of use, a significant acceleration in the speed with which your process can be managed, and integrated capabilities, such as fieldbus, advanced control and batch.


Smart Plants Made Easy

Designed with this new architecture in mind, the DeltaV system fully integrates ‘smart plant’ capabilities including HART®, FOUNDATION™ fieldbus, high-speed discrete busses, and embedded advanced control. This seamless, intelligent field integration enables Asset Management Solutions (AMS) for quick, easy re-ranging, configuration and diagnostics. The result is better process efficiency and reduced process variability.


Any Size You Want

DeltaV is scalable in both size and functionality. It’s the first system to offer you a single architecture with full functionality from small to large, so you can cost-effectively implement applications of any scope. You pick the functions that work best for your application across the entire system size. No longer are you constrained to an automation solution based on project size.


Leading the Way

The DeltaV system has delivered a host of industry firsts—including simple plug-and-play OPC integration, and embedded FOUNDATION fieldbus, batch, and advanced control technologies. Being first with these technology innovations has made our users pace-setters in their industries. But more important, it’s delivered dramatic operational improvements. The kind of improvements you can start profiting from today.


The Result

The return on your total automation investment is higher with the DeltaV system —because your operational benefits increase while your automation costs decrease. In the following pages, you’ll see how the DeltaV system is expanding the boundaries of process automation, improving your project cycle time and your operation performance—from installation and start-up, to daily maintenance and operations—all made easy.


The revolutionary PlantWeb architecture changes the economics of process automation, and the DeltaV system makes it easy.




The DeltaV system scales the complete range of applications from an isolated process area to a complete plant-wide automation system. Whether you need tens of I/O or tens of thousands of I/O—any size you want! The DeltaV system provides all the tools to manage your process easier than ever before.



The complete family of controllers is available to power your most advanced control strategies. Full controller and power supply redundancy is available for your mission-critical applications. The controller and I/O sub-system is rated for Class I, Division 2 and Zone 2 environments to reduce your installation costs.



The DeltaV system has the I/O technologies to meet your toughest applications. These include:

iFOUNDATION fieldbus. Field-proven since 1997, FOUNDATION fieldbus fundamentally changes your project economics. It’s built from the ground up into the DeltaV system.

iDiscrete Busses. AS-i bus, Profibus DP, and DeviceNet provide you with high-speed discrete bus solutions.

iHART. The DeltaV system supports the full breadth of information HART-based field instruments provide.

iSerial. The DeltaV system can act as both a MODBUS master and MODBUS slave device to fully integrate with any automation system you currently have. Other popular drives are     available.

iClassic. The classic I/O interfaces support a full range of analog, discrete, thermocouple, and RTD card types.

iIntrinsically Safe. Available for many popular Classic and HART I/O types.


DeltaV Workstations

DeltaV workstations are based on the latest Intel-based microprocessors running the Microsoft Windows NT operating system. A complete range of applications is provided to cover system configuration, operator interface, engineering, maintenance, and integration functions.


Communications Network

The DeltaV control network—a high-speed Ethernet LAN—provides system communications and connects the various system nodes. The control network can be fully redundant. DeltaV remote     services extend the operations, engineering, and diagnostic applications across your enterprise network.




The DeltaV system is built on fundamental ideas that support plant automation - made easy.


Built for Bus.

The DeltaV system is credited with the world’s first FOUNDATION fieldbus installation. This and other installations are delivering formidable results. Like 74% reductions in field wiring, 93% reductions in required control room space, 80% reductions in field device commissioning time.* And that's just the beginning!


The DeltaV system incorporates the FOUNDATION fieldbus function block set, enabling you to run control where it makes most sense; either in the fieldbus device or in the DeltaV system.


The DeltaV ‘built for bus’ architecture auto-senses FOUNDATION fieldbus devices as they’re added to the fieldbus segment, greatly simplifying the installation and engineering process. High speed discrete busses AS-i bus, DeviceNet, and Profibus DP —also key to the DeltaV ‘built for bus’ architecture —the ability to address those areas where many discrete devices are located.


Asset Management

Maintaining your plant field devices need not require sending technicians into harsh, remote, or hazardous locations to check instruments. The Asset Management capabilities inside DeltaV allow easy FOUNDATION fieldbus and HART device configuration, re-ranging, and remote diagnostics.



In another industry breakthrough, the DeltaV system delivered the world's first OPC and Microsoft Distributed COM solution.


The DeltaV OPC server allows simple plug-and-play integration of information from any external OPC-compliant system. The DeltaV system's data acquisition and calculation applications let you seamlessly add external information into your graphical displays, control strategies, and smart alarms.


Unit Management

The DeltaV system’s use of OPC and MODBUS technologies means you can easily integrate with your existing PROVOX®, RS3TM, Honeywell, Bailey, or other systems. If your process application requires complex batch processing, the DeltaV system’s ‘built for batch’ architecture can make it simple. This architecture provides a comprehensive set of easy-to-use tools for cost-effective batch control solutions.


Both batch control and recipe management components are tightly integrated, eliminating multiple configuration databases and ‘no value’ data mapping exercises commonly associated with many ‘flanged’ batch solutions on the market today.


Common Communications Foundation

Unlike PLC/HMI solutions, the completely integrated DeltaV system features a single database that coordinates all configuration activities. System configuration is globally distributed in the run-time environment.


This distributed real-time database creates a common communications foundation that provides:

iAccess to all system information by name. No physical location references are required.

iAutomatic and transparent node-to-node communications.

iSingle global system database.


No database mapping is required for communication between DeltaV workstations and controllers.


Other suppliers’ OPC-enabled applications can use the same communications foundation to access any system information by name.



Remote Access

All configuration, operating, diagnostic, and history applications can be securely accessed remotely across your plant LAN and via modem. Additionally, the DeltaV Web Server gives you access to all your operating and trend information through a standard web browser.


Easy to Learn

The DeltaV system is inherently easy to learn and use. Examples of this built-in ease of use include:

iIntuitive user interface similar to the Microsoft Explorer.

iIntegrated, context-sensitive, on-line help.

iOperator graphics layout including display navigation and alarm management.

iAuto-sensed controllers are physically connected to the control network and auto-sensed IEC 61158 FOUNDATION fieldbus devices are connected to a fieldbus segment.

iA library of  pre-engineered control modules reduces your engineering efforts.

iCut, copy, and paste control strategy development uses simple drag-and-drop modification built to the IEC 61131-3 standard for control strategy development.

iAnd if the system’s built-in control strategies don’t fit your operating and control philosophies, you can quickly and easily create new ones that do.



DeltaV modules let you manage system information as modular components, similar to how you already manage your field devices. These modular components have unique names and specific characteristics, and can be downloaded and modified independently from one another.


Modules are defined as one or more field devices and their related control logic. Loops, motors, and pumps are typical examples. Each module has a unique control tag and contains control strategy diagrams, parameters, alarms, conditions, events, and history.

DeltaV modules are:

iunderstood system-wide by all DeltaV components

iautomatically available throughout the system

ia focal point for system-wide access to all contained control data

icommunicated within the system by their name

icommunicated to integrated external applications by their names.


These capabilities are not limited only to those modules that are pre-engineered and supplied with the system. You also have complete flexibility to create your own standard modules that use all of the same capabilities.


The DeltaV modules are based on the IEC 61131-3 and the S88.01 definitions of hierarchy and offer a modular approach to configuration development. The S88.01 standard provides a sound structure for control development, while allowing full latitude to define modules appropriate for your process needs.


The DeltaV modules put you in control of the configuration process, making it easy for you to engineer your system, your way—whether you do bottom up or top down design and implementation.


The DeltaV system’s pre-engineered module templates enable fast, easy system implementation. Using simple drag-and-drop features, it takes only seconds to create a completed module. All modules are fully customizable for you to add your solutions to the library and to share across your organization or with other users across the internet.


The system’s auto-sense capability builds your configuration as you plug in the system and FOUNDATION fieldbus components. Just plug in your DeltaV cards and fieldbus devices and you're ready to go.


Easy to Upgrade

The DeltaV upgrade utility makes it easy to upgrade your DeltaV system from one revision to the next. Most tasks are performed automatically and the others guide you step by step through the process. Both on-line and off-line upgrades can be performed.


Embedded Advanced Control

Better plant performance is now possible by combining the information in intelligent field devices with the DeltaV system’s advanced control applications. From advanced tuning, through continuous process inspection, predictive modeling, and simulation, you can easily leverage this new wealth of information. And, these advanced control solutions are easy to deploy and maintain with the DeltaV system.





The DeltaV workstations provide you with a complete user environment that supports a broad range of functions—from operating and analyzing the process, configuring and maintaining the system to integrating DeltaV to the rest of your facility. Each function offers a simple, visually intuitive user interface.


The DeltaV workstation hardware is based on commercially available components. These include high-performance PCs based on the latest Pentium processor technology running the Windows NT operating system.


Workstation Hardware

The DeltaV workstation grows in performance as PC performance advances.

Since your DeltaV workstation arrives pre-installed and ready to go, you can do more of what you want to do, instead of spending time installing software. Ease of use defines the DeltaV workstations. No fuss, no trouble-shooting —just plug-and-play.


DeltaV has all the options you need to support any size installation. Dual head monitors, fault tolerant workstations, rugged touchscreens and keyboards are all available. Check the latest product data sheets on for the full range of options.


Workstation Software

The DeltaV workstation software delivers high performance, conveniently packaged software suites to meet your needs.


All workstation software suites come fully loaded and enabled with DeltaV integrated TCP/IP communications. Forget the no-value fussing with DLLs or DDE. With DeltaV communications, you're ready to go.


The DeltaV workstation software is divided into four classes of functionality:

iSystem Definition. This software suite contains the global database where all aspects of your DeltaV system are defined and maintained in addition to the operations and engineering software suites.

iOperations. These applications are used by plant operators and supervisors to control and manage the process.

iEngineering. These software applications are typically used by the engineering and maintenance staff to optimize plant operations.

iIntegration. Your DeltaV system would not be complete without seamless integration to the rest of your plant. The DeltaV OPC server and OPC Mirror facilitate sharing process data with client applications across the plant local area network.


These four classes of software functionality have been bundled into suites for your convenience:









The ProfessionalPLUS software suite contains the DeltaV global database. This completely integrated database coordinates all configuration activities. Forget about data mapping between separate databases or referencing your process and engineering information by arcane registers or numbers. All your DeltaV information is named and easily browsed by name—just like you browse the files on your PC.


All communications between the DeltaV workstations and controller nodes along the control network is automatic and transparent to you.


The ProfessionalPLUS software suite can manage security and access to all of the DeltaV software applications. At each DeltaV workstation with operator functionality, users can be limited to certain plant areas for viewing and operating. This security feature can be defined for an individual station, as well as for specific users. Out of the box, you get a library of control strategies and operator controls to get you going quickly and easily.










System Definition



















This suite contains system configuration, engineering, operations and communications.  Complete system-wide security and state-of-the-art object-oriented database is provided.







The Professional suite contains engineering, operator, and communications functions – allowing you to switch between engineering at startup to operations as the plant comes on line.







The Operator suite contains operations and communications software – all of the tools you need for complete control over your process.







This is a multi-purpose station available for

iPlant history    iBatch history    iIntegration functions







If none of the options above meet your specific requirements, the base station suite gives you the flexibility to individually select software applications from many available.






The DeltaV operations software suite provides an easy-to-use environment for process operation and information access. All operations applications are fully remoteable for access anywhere on your plant LAN or via modem.  Operations applications may include:

     iOperator Interface                    iDiagnostics                 iContinuous History Viewer


Operator Interface

With the DeltaV Operator Interface, you get high-resolution graphics, providing detail and information display flexibility. A standard operator desktop and operating philosophy for all modules provide an easy-to-use, highly reliable operator environment. The bottom line: less training time, and better process operations.


Even better, operating faceplates, detail displays, and process equipment are already pre-engineered. Start with a pre-built control strategy, give it a name, drag, drop, and install it in a controller, and you automatically have associated operating faceplates—easy.


The DeltaV Operator Interface incorporates operator graphics, sophisticated alarm management and presentation, real-time trending, and on-line, context-sensitive help.


You can easily create smart alarms. These can be a combination of other alarms and process conditions. Unlike other control systems, which require a separate expert system to achieve smart alarms, the DeltaV system’s are built right in.


The real-time trends in the Operator Interface give you a quick overview of your process performance. One or more real-time trends can be embedded in the process graphics.



The DeltaV Diagnostics Explorer gives you a complete top-to-bottom, system-wide view—even down into your smart field devices. If you know how to use an explorer, you already know how to use DeltaV diagnostics. Nothing to build or engineer. Diagnostics are ready to use, right out of the box.


View any node across the control network and incorporate diagnostic data into operator graphics, smart alarms, Excel, or OPC applications.


Continuous History Viewer

The DeltaV Continuous History Viewer, built on OSI's PI Server, helps you pinpoint trends and events affecting plant operation. View your operation's continuous, event, and batch data with real-time and historical trends.


The DeltaV system makes history collection and control easy. Each control module—the fundamental building block of control strategies—maintains the historical configuration information for all of the module parameters. Click and drag plant areas in the DeltaV Explorer onto the historian folder and all modules within the area are automatically historized—easy.

You can add additional OSI PI components like the PI System Gateway to SAP R/3 for

enterprise integration and PI DataLink for easy Excel integration, to name a few options.

The DeltaV Continuous History Viewer gives you a view into operational events, such as operator changes, control module installations, alarms and device status changes.


If you use the DeltaV Batch capability, the Continuous History Viewer provides you a view of recipe execution data on a batch basis so you can make batch-to-batch comparisons and analyses. It also displays important production data from each batch run. If you are a DeltaV Batch user, check out the DeltaV ‘built for batch’ brochure for more on the most integrated batch history available.



The DeltaV suite of engineering tools handles configuration management, both locally and remotely, for all aspects of the DeltaV system. Users can concurrently configure the system and access the global configuration database.


To make your project engineering activities easy, a library of pre-engineered, reusable module templates and pieces of control strategies (composite templates) is built in. You have full control over modifying pre-engineered control strategies to meet your operational philosophies. You can save, share, and swap your control modules in the library.


The DeltaV Explorer—the primary navigation tool for DeltaV system configuration— automatically highlights items that have modified configurations and that need to be downloaded. You can select to download a single change, multiple changes, or the complete system.


Key elements of the DeltaV engineering applications include:

iDeltaV Explorer - presents the complete system configuration in a single view and allows direct access to any item.

iDisplay Configuration - provides display and dynamic graphic symbol configuration.

iControl Studio - provides graphical control strategy configuration, on-line view, and debug capability.

iConfiguration Assistant - a software tool that takes you step by step through system configuration.

iAsset Management Inside - an application which performs configuration, re-ranging, and remote diagnostics for your FOUNDATION fieldbus and HART devices.

iRecipe Studio—an environment that develops and manages batch recipes.


DeltaV Explorer

The DeltaV Explorer is the primary navigation tool for system configuration. It presents the complete system configuration in a single view and allows direct access to any item.

The DeltaV Explorer allows drag-and-drop moving, copying, and assigning of items. You can copy a control module template from the library by selecting it and dragging it to the area where you want to create a new module.


When a new controller and I/O are connected to the system, the controller is immediately auto-sensed. When you select the controller, drag it to the control network, and give it a name, you’ve defined a new controller. The I/O interfaces are also displayed as components of the controller.


Display Configuration

Display configuration is simply a mouse click away.  Use standard tools such as cut, copy, paste, and drag-and-drop to easily configure your displays.  You can easily use scanned plant images with actual process dynamics, attach sound to a display, and even build your own animated movement into graphic symbols.

The pre-defined standard operator desktop template simplifies the typical effort of designing your own displays and operating display layout. What information is important, where it should be displayed, and common operating navigation methods are all provided, simplifying your engineering effort.


The pre-defined graphics and dynamic display symbols have embedded script language and logic capabilities. This gives you built-in coordinated display management and dynamic symbol definition.


In addition, the standard module templates include pop-up faceplates, trends, and detail displays, and support discrete, analog, and sequential control module operation.


All DeltaV information is available for display on any process graphics. Unlike other pieced-together solutions, ‘no-value engineering’ is eliminated—special database mapping of the information is no longer necessary.


You do not even need to know the physical location of a module to use its information in a graphics display. All you need to know is the name of the module, and you can simply browse the system for that loop. This browsing even extends to any parameters of modules, including setpoints, status, and tuning.


Control Studio

The DeltaV Control Studio lets you graphically create, modify, and troubleshoot your control strategies. All module control strategies are easily and quickly assembled using drag-and-drop and cut, copy, and paste methods which shorten and simplify your project engineering.


With a choice of IEC 61131-3 graphical control languages, you can select the language that’s appropriate for the type of control functions your process requires:

iFunction Block Diagrams (FBD)—closed loop control functions and continuous calculations

iSequential Function Charts (SFC)—control tasks that are sequential

iStructured Text (ST)—advanced calculations and expression evaluation.


You can also intermix these control languages within a single control module. Thus, a module can leverage function blocks for closed-loop analog control and sequential function charts to perform startup sequencing. All modules are treated as separate entities in the Control Studio, letting you focus on a specific module without impacting other modules running in the same controller.  Because the underlying languages are graphical, there is no translation between what is viewed during configuration and what actually executes in the DeltaV system.


This intuitive graphical representation of your control strategies allows you to use your actual configuration as your control strategy documentation, instead of creating separate documentation.  You can configure modules without first defining the controller where the module will execute which simplifies your engineering efforts.


The Control Studio runs in two modes: edit, and on-line. Edit is where the control strategies are built, using simple drag-and-drop techniques. On-line lets you view its actual execution. You can also debug the strategy from this same graphical view, and use all the troubleshooting tools you need, including breakpoints, single step, force, and override control.


Configuration Assistant

The Configuration Assistant provides information and configuration guidance for new and occasional DeltaV system users.  Using an approach similar to Microsoft Wizards, the Configuration Assistant teaches you system fundamentals while you configure the system.  The Configuration Assistant takes you step by step through each section of the system, providing context-sensitive help for each topic.


Asset Management Inside

With the Asset Management Solutions (AMS) built inside your DeltaV system, configuration, calibration, and remote diagnostics of your field devices has never been easier. This integrated environment eliminates the need for any additional hardware or parallel wiring. This fully integrated approach is the first in the market to combine process automation and asset management.


With AMSinside the DeltaV system, maintaining your device database is easy. Device information is available online. Time-consuming paper records management is eliminated.

You can quickly and conveniently change configurations from the workstation and download them to field devices. This auto configuration streamlines configuration in half the normal time, and improves the accuracy of your work. You can set configuration parameters from the control room, as well as minimize the time spent in validating a loop problem.


Your fieldbus devices can be re-ranged and calibrated from any workstation, significantly reducing time spent on routine preventative maintenance procedures and improving accuracy of the work. Automated tools reduce the time to commission devices.


You get more comprehensive remote diagnostics than ever before. You have complete on-line access remotely from your workstation to device status and diagnostics, reducing the number of field trips that end up with ‘no problem found.’




The DeltaV suite of embedded Advanced Control products gives you the capability to develop the right control strategies for your plant automation needs, at a fraction of the traditional cost. It continuously monitors the performance of those strategies to improve and optimize them over time. All this makes for a better performing automation system and a better performing plant.


DeltaV Neural

Neural networks are capable of modeling noisy and non-linear processes better than other techniques. The DeltaV Neural embeds this advanced technology right into the controller with automatic pre-processing, design, training, and verification.


DeltaV Predict

Embedded in the controller, DeltaV Predict comes with pre-configured operator interface that makes model predictive control easy.


DeltaV Inspect

Consider DeltaV Inspect your own personal loop inspector, focused on one thing— improving your plant’s performance. Loop by loop, DeltaV Inspect seeks out excessive variability and recommends how to eliminate it.


DeltaV Simulate

Simulations model process conditions, enabling you to better understand the process being controlled. The simulation uses the actual I/O of the DeltaV system to simulate field device behavior and response. You get a complete set of simulation tools that allow process information to be imported directly from the DeltaV system.


DeltaV Fuzzy

Far superior to PID control, fuzzy logic control gives you faster response times, virtually no overshoot, and greater tolerance for noisy signals. If your process experiences frequent set point changes and load disturbances, DeltaV Fuzzy is your best bet to minimize the impact. And, the best part of all, like all DeltaV products, it’s easy to use.


DeltaV Tune

To simplify tuning of fuzzy logic loops, as well as standard PID loops, the DeltaV system has an easy-to-use auto-tuning capability. Operators and maintenance personnel can quickly tune loops to keep the process running at peak efficiency.

It connects your OPC server to one or more OPC servers on other systems, software, and devices. You can use DeltaV look-and-feel applications to configure the Mirror application and then the Mirror takes over—pushing values back and forth between systems.


OPC Pager

As your constant watchdog, the OPC Pager monitors data from your OPC server, keeping an eye on critical process values and notifying you when they meet your criteria. The OPC Pager works with alphanumeric pagers that use the TAP communications standard.


Web Server

Now you can view your plant process graphics in any standard web browser anywhere in the world with the DeltaV Web Server. You also have browser access to historic and real-time trends, and Event Chronicle alarms and events.


Data Acquisition

You can do data acquisition by having DeltaV monitor inputs resident in the DeltaV workstations. You can store data from other supplier systems and devices for use as native DeltaV I/O. You can use this data in your DeltaV control strategies, smart alarms, trends, operator displays, or data historian. OLE for Process Control (OPC) moves the data into and out of DeltaV.


This data acquisition capability is sized to bring existing automation systems and PLCs throughout your plant into the DeltaV system, easy. Even better, you get all the standard DeltaV engineering, operating, and diagnostic tools, which means no separate interfaces to learn.



Using DeltaV control modules resident in the workstations, you can perform a wide variety of computations on the external data brought into the DeltaV system. A complete range of mathematical functions allows you to do performance, financial, or efficiency calculations.

Now you can work with the standard DeltaV applications. Your calculations are built with the standard IEC 61131-3 control languages. Forget about custom tools and custom coding—it's native.

Optional DeltaV Applications

You can include many of the popular DeltaV applications, including History Display, Diagnostics, and scheduled reporting, to extend the performance and functionality of the workstation.


User-Written and Other Supplier Applications

The Application workstation is the perfect environment to develop your own custom applications using familiar tools like VBA in the Microsoft Office suite, Visual Basic and Visual C++. Or you can add applications and proprietary drivers from other suppliers to provide comprehensive automation integration.




The DeltaV controller delivers a very compact footprint, can be widely distributed across your facility, and scales to meet your automation applications of any size.


The controller gives you a wide range of control and monitoring functions, including:

iFull redundancy of the controller and power supplies for mission-critical operation

iCompact, rugged DIN rail-mountable hardware

iMonitor, control, and advanced unit management levels of functionality

iComprehensive continuous control

iEmbedded advanced control

iExtensive use of IEC, ISA, and FOUNDATION fieldbus, HART, and discrete bus control standards.


The DeltaV control software is a family of high-performance software that runs on the DeltaV controller. The controller lets you efficiently control everything, from basic monitoring to the most complex advanced control strategies for non-linear and highly integrated processes.

The system offers the best possible combination of the IEC 61131-3, ISA S88.01, and FOUNDATION fieldbus ISA SP50 and IEC 61158 standards for control functions.


The IEC 61131-3 standard provides easy-to-use graphical control languages.

FOUNDATION fieldbus standards are used and extended for function block development. This approach enables control strategies, developed using the DeltaV system, to execute in a FOUNDATION fieldbus device. AS-i bus, DeviceNet, and Profibus DP are also supported for your high-speed discrete bus needs.


The ISA S-88.01 standard offers the system the necessary hierarchical structure and enables easy, intuitive management of the relationship between various control strategies.


Control Software

Software for your DeltaV controllers is completely scalable in size and functionality. You get to easily tailor the amount of monitoring, control, and advanced unit management. Only the DeltaV system offers this level of flexibility—made easy.

This fully scalable approach gives you the ability to grow online as your process needs change, both in size and functionality.

You also decide where the control should execute…

in the controller,…    in the field devices,…    or even in the workstation.


Whatever makes most sense for your application. Not only can you select the mix you need at the start of your automation project, you can change the mix over time between controllers.

You select from three levels of control software: monitor, control and advanced unit management, enabling you to select only the capabilities your process requires.



Monitor inputs are those that do not require control, but can be scaled, displayed, alarmed, historized, event-tracked, and can be reported and analyzed. These signals are often associated with data acquisition and other non-control information.



Control inputs and outputs have all the functionality of monitor signals, with the addition of providing full analog and discrete control capabilities. You have the flexibility within function blocks to manage data manipulations, calculations, logic control functions, and sequences. Additionally, you can organize your control inputs and outputs around units for additional alarm management capabilities. Best of all, you get a library of pre-engineered modules so most of your work is already done.

Advanced Unit Management

Advanced Unit Management adds class-based units and phase logic used for both batch processes and complex sequences in continuous and hybrid processes. With this class-based approach, you get reusable equipment control strategies—saving you time. Additionally, the state transition diagram logic built into the phase class provides you with multiple phase states, automatic state switching, and failure monitoring—all pre-engineered. The phases and units executing in the controller support aliasing and dynamic referencing for your most demanding applications. And the phases may be orchestrated by the DeltaV recipe management and execution software including the use of recipe parameters and history collection.





Engineering is easy with the three graphical control languages within the DeltaV modules:

·         Function Block Diagrams (FBD)— Continuous calculations and closed-loop control functions

·         Sequential Function Charts (SFC)—Control tasks requiring time-variant sequencing

·         Structured Text (ST)— Textual based logic development

All three languages execute within the controller in their native form without translation from one language to another prior to execution. What you see on the diagram is exactly what executes.


Function Block Diagrams

DeltaV system function blocks are implemented using the structure specified by the FOUNDATION fieldbus standard, but they are also enhanced and extended to provide greater flexibility in control strategy design.

A robust set of available function blocks, including module blocks, allows one control module to be represented on the diagram of a different control module, enabling the interactions between several control strategies to be visually created and easily maintained.

iComposite blocks improve strategy readability and engineering effort by representing a group of function blocks, or SFC steps, on the diagram. They provide a hierarchical grouping to segment your strategy, maintain common functions in the library, and intermix control languages within the module.

iComplex blocks are single-function blocks that combine input/output functions, the transfer function, and alarms. These blocks save development and testing time. Most motors, discrete valves, and analog control loops can be implemented with a single complex block.

iExtensible blocks allow you to easily extend the inputs and outputs within the block.

iExpressions execute simple or complex calculations, perform conditional checks, and perform system-wide reads and writes.


Sequential Function Chart

SFCs are useful to depict and control sequential processing behavior. They’re best at controlling strategies requiring multiple states. Transitions allow single-stream or parallel logic execution within the SFC. Standard modes and commands for controlling sequential function charts are provided within the standard structure of the DeltaV system.


Structured Text

The DeltaV system uses the IEC 61131-3 Structured Text instruction set to create custom calculations and algorithms. The instruction set uses operands, operators, functions, and constants to create text expressions. You have tremendous flexibility to perform calculations since every system parameter may be referenced by these expression commands.




The DeltaV control hardware delivers big cost savings to the installation process. The compact, modular design allows you to build controller nodes that cost-effectively meet your process needs. With the FM Class 1, Division 2, and CENELEC Zone 2 certifications (pending), you

can locate entire control hardware components including carriers, power supplies, controllers, I/O cards, and terminations in these hazardous locations.

This packaging design supports installation into field enclosures, near the field devices. The hardware design is based on DIN rail-mountable, modular carriers. Wiring and marshalling panel costs are reduced, saving valuable control and instrument room space as well. Both horizontal and vertical mount options are available to best suit your installation.

With FOUNDATION fieldbus and discrete bus installations, the savings are even more significant. Control room space, instrument-wiring costs, and termination costs can be a quarter or less than a comparable installation with classic I/O technology.



The DeltaV controller provides communication and control activity management between the field devices and the other nodes on the DeltaV Control Network. You have the choice of redundant or simplex controllers, depending your process requirements.

The DeltaV controller saves engineering and installation time by automatically identifying itself to the DeltaV Control Network when you plug it in. A DeltaV workstation automatically assigns the controller a unique address, making controller information available to all nodes on the control network eliminating  ‘no value engineering’ efforts.

The controller also automatically detects any connected I/O card. As soon as an I/O card is plugged in, the controller detects the new I/O functionality and notifies the system to again simplify engineering.



The DeltaV I/O subsystem is designed to open down, allowing you to tap the intelligence of today’s digital field devices.  Once the system is running, you can remove and install I/O cards under power without disconnecting or moving any I/O wiring.  You can view and configured new I/O interfaces from the DeltaV Explorer.  For your convenience, each I/O interface contains pre-defined default settings. This minimizes the controller configuration effort and helps you get your process online faster.


You can use any combination of FOUNDATION fieldbus, HART, Serial, Classic I/O, and AS-i bus, DeviceNet, or Profibus DP discrete bus technologies to optimize your installation, engineering, and operating costs.



FOUNDATION fieldbus standard is inherent in the DeltaV ‘built for bus’ architecture. Auto-recognition—the ability to recognize what specific type of FOUNDATION field device has been installed—is a key element in this ‘built for bus’ architecture. Unlike today’s DCS-based systems, the DeltaV system provides an unrestricted flow of information from these intelligent field devices into the DeltaV system and throughout the plant through DeltaV remote applications and OPC connectivity.


For example, if a new fieldbus device is installed on a H1 segment, the DeltaV system will automatically recognize the type of device, manufacturer, serial number, software revision and functionality supported by the device— dramatically reducing your installation, checkout, and engineering expenses.


The fieldbus H1 card makes adding fieldbus devices to your DeltaV system easy. This card slips into any vacant slot in the I/O carrier, alongside your other I/O cards.

Coupled with Asset Management Inside the DeltaV system, which delivers device configuration, calibration, and remote diagnostics of your fieldbus devices, your commissioning and ongoing maintenance programs are substantially reduced.

High Speed Ethernet

Enhance your remote I/O via a high speed Ethernet fieldbus segment. Now you have the choice of using your existing field wiring for FOUNDATION fieldbus H1 segments or using high-speed ethernet for your fieldbus devices.



Both HART analog input and output I/O cards are available for your HART field devices. HART information is available to any node in the DeltaV control network. The information can be used by the application of your choice without requiring any additional equipment or wiring.



Through the serial card, the DeltaV system can be both a MODBUS master and a MODBUS slave device to give you complete flexibility in integrating with your legacy automation systems.


As a MODBUS slave, the DeltaV system can integrate as I/O into your MODBUS compatible automation system.  As a MODBUS master, the DeltaV system easily accepts information from your current automation system and makes this information available for operator graphics, control strategies and smart alarms, and it can be served anywhere across the plant through the DeltaV OPC Server.


With both MODBUS slave and master capabilities, the DeltaV system easily connects with PROVOX, RS3, and a host of other DCS and PLC-based systems.  The programmable serial cards also provide easy integration with popular industrial serial devices, such as weigh scales, barcode readers, PLCs, and gauging systems.


Intrinsically Safe

Much of the Classic and HART I/O cards are available in intrinsically safe models.



All the discrete ins and outs, and the 4-20mA analog ins and outs you’ve come to know and love over the years are available in the DeltaV system. Redundant I/O is available for Classic I/O.  I/O termination options provide local wiring, channel isolation, and fusing. An optional integrated shield bar kit for terminating wire shields is also available.


The physical design of the I/O termination ensures that only the I/O card type that matches the installed I/O termination can be used. This design further simplifies the installation and maintenance of the DeltaV system.


Discrete Buses

You can select AS-i bus, DeviceNet and Profibus DP to handle your high-speed discrete processing needs or areas of your process with large concentrations of discrete devices.
