4. Finally, give the alias a value in the search criteria and use the rule sets to ﬁ nd the tags of interest.

2.4 How to Create the DeltaV Control Strategy

Having got to this stage, you should already have searched for and created a list of signals that you are interested in exporting to DeltaV. See the How to Search for Signals section for instructions.

1. Before you begin, decide if you want to modify the default names for control strategy areas and modules. See the How to Modify Default Control Strategy Areas and Module Names topic for more information.

2. Also before you begin, consider how you will convert your OpenEnterprise tag names so that the DeltaV 16 character limit is not broken. See the Tag Format Page for further information.

3. Add Area and Module nodes to your control strategy using the DeltaV Pane. See the DeltaV Pane topic for more information.

4. Select the required signals and drag them from the Search List pane to the DeltaV pane. For more information see the Search List Pane topic.

5. Check the status pane to see if there are any signal names that need to be changed. See the Status Pane topic for more information.

www.EmersonProcess.com/Remote 5

OpenEnterprise DeltaV Export Configuration Tool

6. Modify or shorten signal names. See the How to Modify Signal Names topic for more information.

7. If there is no further warning about tagnames in the Status Pane, click the [Export] button at the top of the DeltaV pane. See the DeltaV Pane topic for more information on the [Export] button. This will export the .FHX ﬁ le using the ﬁ le name and location conﬁ gured on the General Properties Page.

8. From the DeltaV ProPlus workstation download this control strategy ﬁ le to the virtual controller on the DeltaV RTU Connect machine.

2.4.1 How to Modify Default Control Strategy Areas and Module Names

1. Select Tools > Properties from the Export Conﬁ guration Tool menu bar.

2. Select the Tag Format page. The Area / Module name format section at the bottom of this page contains input ﬁ elds to change these default names. See the Tag Format topic for more information.

2.4.2 How to Modify Signal Names

1. If you have many signals to change and you can live with a shortened format being applied to all tagnames: a. Select Tools > Properties from the Export Conﬁ guration Tool menu bar. b. Use the tag format page of the properties dialog to make the necessary changes. c. When you have ﬁ nished making the changes, click the [OK] button at the bottom of the Tag Format page,

and you have the choice of applying the name changes immediately. See the Tag Format topic for more information.

2. If you only have a small number of tag names to change: a. Use the left and right buttons in the DeltaV explorer view. These will be highlighted if any tag names

require a name change. b. On pressing the right button the next signal requiring a name change will be highlighted for modiﬁ cation. c. he left and right arrow keys can also be used instead of the buttons. This particular method is useful if

you want to modify only the tagnames that require changing (rather than forcing tagname changes to be

applied to all signals). See the DeltaV Pane topic for more information.

3. Knowledge Base

The aim of this section is to help you to understand how the DeltaV RTU Connect integrates remote RTU data collected by OpenEnterprise into DeltaV systems.

A diagrammatic representation of DeltaV RTU Connect integration is shown below. The headings below it will explain each element of the diagram.

3.1 DeltaV Plant

The RTU Connect enables RTU data to be integrated into a DeltaV system using the following DeltaV components:

An application station running OpenEnterprise which is collecting data from RTUs. A DeltaV virtual controller which makes the data from the RTUs available to the DeltaV system. A second application station running the PI historical database and the Plantwide Event Historian to provide historical

signal and alarm-event data from the RTUs.

www.EmersonProcess.com/Remote 7

OpenEnterprise DeltaV Export Configuration Tool

3.2 ProPlus Workstation

The ProfessionPLUS (or ProPlus) workstation is used to provide a single administrative point of entry, allowing for access to all aspects of a DeltaV integrated solution (including third party applications).

The ProPlus workstation also contains the central DeltaV conﬁ guration database. A ProPlus workstation is a

requirement of every DeltaV network. There can be only one ProPlus workstation per system.

3.3 Operator Workstation

A DeltaV operator workstation provides standard plant operational capability. This includes the use of control displays, real-time and historical trending capabilities and the ability to view and process alarms.

3.4 Application Station

As part of the DeltaV suite a user can conﬁ gure a desktop or server to host a DeltaV application station. The application station is used to integrate DeltaV and other applications into the enterprise. A single system can host up to 20 application stations, each with their own virtual controller.

The DeltaV RTU Connect is installed onto a DeltaV application station. Typically, the OpenEnterprise part of the RTU Connect will be installed on one application station and the Plantwide Event Historian and PI Historian are installed on a separate application station.

March 2012

3.5 DeltaV Controller

A plug and play controller that executes control logic based on the process signals derived from the I / O subsystem and provides communication to the rest of the DeltaV control system for operator interaction and data collection.

The controller’s primary function is to execute control modules that are designed to meet the speciﬁ c control requirements of the plant. These control modules use process signals from the controller’s I / O subsystem and provide communication of process data to the rest of the DeltaV control system for operator interaction and data collection.

3.6 Virtual Controller

This is an IEC 61-1131 emulated DeltaV controller (in effect a soft programmable logic controller). The DeltaV Export Conﬁ guration Tool creates a control strategy ﬁ le (an .FHX ﬁ le) that contains references to the remote RTU signals. The control strategy is then downloaded to the virtual controller from the DeltaV system.

The control strategy contains input signal tags which can be arranged by the Export Conﬁ guration Tool within alarm function blocks, linking process signals with their alarm limits.

8 www.EmersonProcess.com/Remote

March 2012

The virtual controller inputs are connected to the OpenEnterprise OPC Data Access server via the OPC Mirror in order to receive real-time data from the DeltaV RTU Connect.

In this way the virtual controller pushes data from the RTU Connect into the DeltaV network to emulate passed through real-time data and alarms from remote controllers.

3.7 Remote Controllers

These are remote ControlWave or ROC controllers that are being integrated into the DeltaV system through the DeltaV RTU Connect.

3.8 Plantwide Event Historian

The Plantwide Event Historian (PEH) captures, stores and displays event data for an entire plant. It records plant event information from any OPC alarm and event server, including the OpenEnterprise OPC Alarm and Event server, and stores that information in a Microsoft SQL Server database.

For more details on how the RTU Connect integrates alarm and event data into DeltaV see the Alarm and Event Integration topic.

3.9 PI Historian

The PI Historian is a standard enterprise database developed by OSIsoft™ that allows for an embedded, centralized alternative to the native DeltaV continuous historian. The PI Historian can be installed onto an application station and embedded into a DeltaV system.

OpenEnterprise DeltaV Export Configuration Tool

The DeltaV RTU Connect streams historical backﬁ ll data via the PI client to the PI historian. DeltaV operator workstations are conﬁ gured to request historical data from the PI Historian rather than the DeltaV continuous historian.

For more details on how the RTU Connect integrates signal history into DeltaV, see the Historical Integration topic.

3.10 OpenEnterprise

OpenEnterprise is an industrial strength SCADA (Supervisory Control and Data Acquisition) system. OpenEnterprise collects data from Remote Telemetry Units (RTUs) using direct low level communications programs and serves the data to clients, normally through standard OPC and ODBC application interfaces.

Typical systems include a processing plant (for instance a well head, pipeline or water processing plant) connected to ControlWave or ROC RTUs and communication systems to transmit the data back to the OpenEnterprise server database.

3.11 OPC Data Access

OPC Data Access is a group of standards that provides speciﬁ cations for communicating real- time data from automation controllers. Real-time data is streamed from the DeltaV RTU Connect through to DeltaV by means of the OPC Mirror application.

For more information on how the DeltaV RTU Connect integrates real time data into DeltaV through OCP Data Access, see the Real Time Integration topic.

www.EmersonProcess.com/Remote 9

OpenEnterprise DeltaV Export Configuration Tool

3.12 PI Client

The Historical Export Application uses the PI SDK to stream historical data from OpenEnterprise to the PI Historian.

For more information on how the DeltaV RTU Connect integrates historical data into DeltaV through the Historical Export Application, see the Historical Integration topic.

3.13 DeltaV RTU Connect

3.13.1 DeltaV RTU Connect

The DeltaV RTU Connect is a suite of software components that when installed together or separately onto DeltaV Application Station nodes within a DeltaV system make it possible to integrate real-time, alarm-event and historical data from remote ControlWave and ROC devices into that DeltaV system:

1. Real Time Integration

2. Historical Integration

3. Alarm and Event Integration

3.13.2 Real Time Integration

In order to allow for the provision of real-time logged data, the DeltaV RTU Connect uses OPC Data Access connectivity.

OpenEnterprise DeltaV Export Configuration Tool

3.13.2.1 The DeltaV Export Configuration Tool

The DeltaV Export Conﬁ guration Tool allows you to select the remote RTU tags that you want to integrate into the DeltaV system. You can then export these tags to a control strategy module ﬁ le (.FHX), which DeltaV downloads to a virtual controller module.

The Export Conﬁ guration Tool also sends mapping information from your selected signals to the OPC Mirror, which enables the OpenEnterprise OPC server and the DeltaV OPC servers to pass the signal data between themselves. The DeltaV OPC server then pushes the RTU data to the virtual controller and it becomes integrated into the DeltaV system.

The Export Conﬁ guration Tool also allows you to conﬁ gure historical integration via the PI Historian.

3.13.2.2 The OPC Mirror

The OPC Mirror is able to create a channel that streams data between two OPC servers. This channel is called a “pipe”. The conﬁ guration required for the OPC Mirror to form a pipe is:

1. The program id of the OpenEnterprise OPC server (let’s call this A)

2. The program id of the DeltaV OPC server (let’s call this B)

3. The direction of the piping a. From A to B b. From B to A c. Both ways (this is the option used)

4. A map of the required signal data.

This is all done automatically when you export an .FHX ﬁ le using the DeltaV Export Conﬁ guration Tool. The Export Conﬁ guration Tool conﬁ gures the OPC Mirror at the same time that it exports the .FHX ﬁ le.

The only thing you will need to do regarding the OPC Mirror itself is to provide a DeltaV administrator name and password when you install it onto the DeltaV RTU Connect application station. The Export Conﬁ guration Tool will do the rest.

3.13.2.2 The OpenEnterprise OPC Server

The OpenEnterprise OPC Data Access server makes data from the OpenEnterprise database available to OPC clients. Its program id is BristolBabcock.BristolOPCServer.

3.13.2.4 The DeltaV OPC Server

The DeltaV OPC server makes data from the RTU Connect available to the DeltaV virtual controller on the application station, which in turn makes it available to the rest of the DeltaV system. Its program id is OPC.DeltaV.1.

3.13.2.5 Virtual Controller

www.EmersonProcess.com/Remote 11

OpenEnterprise DeltaV Export Configuration Tool

The control strategy contains input signal tags which can be arranged by the Export Conﬁ guration Tool within alarm function blocks, linking process signals with their alarm limits.

The virtual controller inputs are connected to the OpenEnterprise OPC Data Access server via the OPC Mirror in order to receive real-time data from the DeltaV RTU Connect.

3.13.2.6 OpenEnterprise

3.13.2.7 Remote Device Interfaces (RDIs)

OpenEnterprise communicates with ControlWave and ROC RTUs using a set of device drivers called Remote Device Interfaces (RDIs). Collected data can consist of current values, history and alarm and event data.

3.13.2.7.1 The ControlWave RDI

The ControlWave RDI is also known as the NW3000 RDI since the original family of Bristol devices were known by the name Network 3000.

The ControlWave RDI (Remote Device Interface) is installed as part of OpenEnterprise. It is a communications program that enables OpenEnterprise to communicate with and collect data from ControlWave RTUs.

™

12 www.EmersonProcess.com/Remote

March 2012

The ControWave RDI’s conﬁ guration program is the NW3000 Setup Tool, which utilizes two other programs:

The NW3000 Signal Builder inserts, modiﬁ es and deletes signals from the database The Template Builder creates polling templates from those signals for efﬁ cient data

The ControlWave RDI requires OpenBSI to be installed on the same machine along with the ControlWave control strategy ﬁ les and network deﬁ nition.

3.13.2.7.2 The ROC RDI

The ROC RDI (Remote Device Interface) is also installed as part of OpenEnterprise. It is a communications program that enables OpenEnterprise to communicate with and collect data from ROC and FloBoss

ROC RDI is has its own conﬁ guration tool which enables you to add ROC devices and points to the database and schedule data collection.

3.13.2.8 Polling of RTUs

The frequency of real-time updates through the OPC Mirror will be restricted by the rate at which OpenEnterprise is able to collect the data. In many cases where only a dial-up connection exists, this may be once a day, and / or on demand. At that time, the RTU Gateway will obtain historical signal data from the RTUs and stream it to DeltaV.

collection.

RTUs.

3.13.3 Historical Integration

There are two methods available for getting historical data from the RTU Connect. It is intended and recommended that most systems use both methods, so that no data is lost:

1. Data pass through. Data is passed directly from the Gateway’s virtual controller via the PI OPC server to the PI database.

2. Use the Gateway Historical Export application to export historical data directly to the PI database.

Method 1 above is good where OpenEnterprise can poll the remote controllers at relatively short intervals.

Method 2 provides a historical backﬁ ll service to the PI historical database if the connection to the remote controllers is lost. If OpenEnterprise cannot poll the remote controllers at short intervals, this will be the main method of integrating historical data.

3.13.3.1 Historical Data Pass Through

Real time signal updates are collected from the Gateway’s virtual controller by the PI OPC server and inserted as historical samples directly into the PI database.

3.13.3.1.7 EntHist Conﬁ guration File The PI database uses ‘PI points’ to store tag information in the pipoint table, each point mapping across to a single DeltaV tag.

In order to conﬁ gure these automatically, the PI historian sources tag information from the EntHist conﬁ guration ﬁ le, created in the DeltaV ﬁ le system.

This is a standard XML ﬁ le containing details of which tags have been conﬁ gured for historical data logging.

The EntHist ﬁ le can only be created when the following has been done:

March 2012

1. The PI historian must be enabled within DeltaV to be the historical data source

2. Signals must have been exported from the Export Conﬁ guration Tool, and downloaded to

the Gateway’s virtual controller.

DeltaV will then create the EntHist conﬁ guration ﬁ le for the PI historian, and the PI OPC Interface will begin passing data through for the tags conﬁ gured in the EntHist ﬁ le.

3.13.3.1.8 PI Historian The PI Historian is a standard enterprise database developed by OSIsoft that allows for an embedded, centralized alternative to the native DeltaV continuous historian. The PI Historian can be installed onto an application station and embedded into a DeltaV system.
