ODVA (originally the Open DeviceNet Vendors Association for historical context) has decidedly discrete manufacturing roots. As it migrated from an emphasis on DeviceNet to Ethernet (and its brand EtherNet/IP), it has also struggled mightily to develop protocols that exploit only commercial off-the-shelf Ethernet chips. It was able to conquer the challenges of Ethernet for real-time and deterministic communication (for example for motion control) without the need to bypass the TCP/UDP part of the stack only recently (CIP Sync and CIP Motion).
Now, as its most stalwart member, Rockwell Automation, has moved strongly into process automation, and as Endress + Hauser has joined, ODVA finds itself needing to work on a protocol for EtherNet/IP for process automation. E+H has already announced implementations of EtherNet/IP for some of its instrumentation.
Within that context, ODVA has announced the availability of a new white paper, Optimization of Process Integration, which outlines a strategic vision for manufacturers wishing to implement an Ethernet solution or, in the words of the marketers of ODVA, “looking to maintain cost-effective, sustainable production capacity in the process industries.” The white paper is designed to help business and technical leaders in these industries define their future network architecture and plan for the efficient integration of their plant’s network infrastructure into existing business applications.
In other words, the white paper is a document around which formation of an industry working group (SIG) can begin to develop the protocols.
From the press release, “ODVA envisions an approach to the optimization of process integration that is convergent, compatible, scalable and open for users and their suppliers. The approach will simplify the exchange of configuration, diagnostic and production data between field devices and higher-level systems, such as supervisory control and data acquisition systems.”
“The approach also will enable plant asset management (PAM) and secure remote access of field installations. This, together with the proven benefits and cost advantages of commercially available, off-the-shelf Ethernet and Internet technologies, will help businesses improve productivity and competitiveness.”
Katherine Voss, president and executive director, ODVA, says that industry will see a continued expansion of Ethernet and IP technologies in automation systems used in process industries. “The Optimization of Process Integration leverages the prevailing trend of convergence in information and communication technologies used in industry and in business applications. As EtherNet/IP is proven in hybrid and discrete industries, it is an ideal technology to provide process industries with a unified communication solution from the field to the enterprise.”
In this white paper, ODVA describes the opportunity for the optimization of process integration (OPI) and an overview of its vision for a comprehensive approach including:
- OPI in the industrial ecosystem;
- ODVA’s vision of OPI in the production domain;
- Industrial use cases for OPI;
- ODVA’s technical approach to OPI; and
- OPI in practice.
Looking at the list of members of ODVA with a process industry emphasis, the only other company that I noticed was Schneider Electric (an ODVA member partly as the godfather of Modbus TCP, which fits nicely). But Schneider Electric had only a small process industry focus until last month. I wonder what the acquisition of Invensys (Foxboro, Triconex) might mean. Something to watch, I suppose.

Once upon a time, I was evaluating starting a cloud-based analyst company. The idea would be to obtain more information about the market or industry through a wide-spread network. Trouble was, I really don’t know the inner workings of the analyst business model. Then, Matthew Littlefield started LNS Research and did it.
The FDT Group is taking a page from that idea by publicly releasing a cloud-based link to its technology roadmap process. Seeking broad industry input and collaboration to strengthen the future capabilities and market scope of the FDT standard is the goal of this program.
“The FDT Group has always been very good at collecting and processing input from a variety of end points within our industry,” observes Dan DeYoung of Rockwell Automation who serves as Chairman of the FDT Group Technology Marketing Committee. “By moving our data collection into a cloud-based technology, we break down the last remaining barrier to individuals and organizations wishing to contribute to the development of our technology roadmap. Industry pundits have contributory access 24/7 and are able to stay up to date on the technology roadmap by requesting push updates as to the
status of their contribution.”
Anyone in the industry is welcome to contribute. The tool allows the contributor to describe the proposed new feature or capability for the FDT standard as well as a simple use case. Options are provided to push updates to the contributor if desired. All input is reviewed and prioritized by the FDT Group Technology Marketing committee. Once incorporated into the technology roadmap, the FDT Group Architecture and Specification committee takes over to engineer the capability into the FDT standard and release it to the public.

This is a significant advance for interoperability between EDDL and FDT (finally!) announced at the ARC Forum last week in Orlando. FDI Cooperation LLC announced the first public release of the FDI Usability Style Guide and a preview release of the Field Device Integration (FDI) developer toolkit. This release of the developer tools and style guide comes close on the heels of the first release of the overall FDI specification at the NAMUR annual meeting in Germany in November of 2013. Both of these preview releases will make it possible for automation suppliers to prepare for developing FDI-compatible products and host systems.
The common cross protocol Integrated Development Environment (IDE) will help device manufacturers create FDI Device Packages for FOUNDATION fieldbus, HART, and PROFIBUS devices. The purpose of standard developer tools is to ensure that automation suppliers can develop high quality, reliable FDI-based solutions in a consistent manner. A standard set of developer tools also significantly reduces development costs and time to market for both device and system developers. The IDE includes a reference host that allows device developers to execute and test FDI Device Package against a standard implementation to ensure product quality. With the release of a beta version, FDI Cooperation offers device and system vendors the possibility to become familiar with the FDI Tools and Components before the first release. The vendors benefit from the early access because they get familiar with the tools and can prepare their own product development. FDI Cooperation benefits from the feedback from the beta users, which helps to improve the robustness of the tools and components.
Developers interested in obtaining the FDI IDE or Common Host Components should contact the respective foundations supporting FDI, including Fieldbus Foundation, HART Communication Foundation, and Profibus International.
Demo of FDI Developer Tools
Stephen Mitschke, director of fieldbus products at the Fieldbus Foundation, demonstrated the current release of the FDI developer tools. Mr. Mitschke showed the functionality of the IDE and how it can be used to develop devices. The functionality of device packages was also demonstrated, in addition to the reference host, which can be used by developers to access the functionality of FDI compliant devices.
The demo of the developer tools was based on the protocol independent FDI Common Host Components. Host system manufacturers implement FDI Common Host Components for device management tools, asset management tools, and process automation systems. FDI Common Host Components will allow for rapid development and ensure FDI Device Packages behave consistently across different systems. FDI Host Components fully support legacy EDD libraries to protect end user investments.
FDI Style Guide
The first release of the FDI Usability Style Guide gives developers best practices and guidelines for building products according to the FDI specification. By following the recommendations in the style guide, suppliers can develop devices with a common look and feel under the FDI specification. The style guide provides additional information related to the technical specifications given in IEC 62769 and IEC 61804 and supports FDI Device Package designers to achieve uniform user guidance and uniform behavior independent of the implementation technology (UID, UIP). The FDI Style Guide will be available for download from the FDI web site.
FDI Specification
At the core of the FDI specification is the FDI Device Package that includes everything a host system needs to integrate an intelligent device. With FDI, each device is represented by a single FDI Device Package that can scale according to the complexities and requirements of each device.
Each FDI Device Package contains a mandatory Device Description (EDD) that provides parameter definitions, structure of the parameters for context specific views, and automated work processes for device procedures such as calibration. FDI Device Packages may also include User Interface Plug-Ins, software components that support advanced device setup and diagnostic functions. Product manuals, documentation, images, electronic certifications and other attachments may also be delivered in the FDI Device Package.
FDI Device Packages make it easier for automation suppliers to develop and integrate intelligent devices because they only need to create a single, unified FDI Device Package for each intelligent device that can work with all host systems and tools, reducing overall development costs while preserving and expanding existing functionality. Users will also find it easier to manage information from intelligent devices with a single device package, instead of juggling different technologies and investing significant capital in custom integration efforts to connect multiple technology platforms.
The five major automation foundations, including the FDT Group, Fieldbus Foundation, HART Communication Foundation, PROFIBUS & PROFINET International, and OPC Foundation have developed a single common solution for Field Device Integration (FDI). These foundations have combined their efforts to form a joint company named FDI Cooperation, LLC (a limited liability company under US law). FDI Cooperation, LLC is headed by a “Board of Managers”, which is composed of the representatives of the involved organizations, as well as managers of global automation suppliers including ABB, Emerson, Endress+Hauser, Honeywell, Invensys, Siemens and Yokogawa. FDI’s mandate is to develop a single technology for the management of information that comes from all intelligent devices throughout all areas of the plant.

One of the announcements made at last week’s ARC Forum in Orlando was this one from Yokogawa. Executives presented this new simulation solution to press on Feb. 10.
Yokogawa Electric Corporation executives said that in April it will begin offering new solutions for optimizing plant operations in the oil & gas, petrochemical, and other industries. These solutions will be provided as part of Yokogawa’s VigilantPlant Services suite to support safe, stable, and highly efficient plant operations. The technology underlying these solutions is Yokogawa’s newly developed MIRROR PLANT online simulator.
The MIRROR PLANT simulator can visualize the internal state of a plant process and make near-term predictions on plant behavior. According to the company, this is an industry first, this simulator operates in synchronization with the plant control system and features the good performance required in commercial plants.
Development Background
In recent years, there has been increasing focus on improving plant safety and strengthening competitiveness by making plants more efficient. For example, in the chemical industry, plant operators need in real time to manage or adjust the state of catalysts and the composition of the reagents and product materials in a chemical reactor, to optimize both plant productivity and product quality. However, many of the process variables are difficult to measure or cannot be measured directly. Based on actual process information such as flow rate, temperature, and pressure, simulation technology can make predictions on items that cannot be measured in real time, for example the amount of each component in a product, and thus simulate the state of a plant. By means of high-speed calculations, the simulator can make near-term predictions on the state of a plant. Operators can then anticipate events and take action earlier to ensure safe operation.
Yokogawa and its subsidiary, Omega Simulation Co., Ltd., jointly developed the MIRROR PLANT online plant simulator. It operates in synchronization with the plant control system and constantly updates a process model. Based on this simulator, Yokogawa will offer support solutions that help its customers optimize their plant operations.
Special notes:
1. Near-term prediction of plant states
The MIRROR PLANT simulator operates in synchronization with the plant control system. Based on real-time manufacturing process information and using a proprietary function for adjusting model parameters, MIRROR PLANT precisely simulates the state of a plant. By using plant models, MIRROR PLANT visualizes the current state of the plant, the state of the plant up to several hours in the future, and the state at plant locations where it is not possible to measure temperature or pressure. It then displays these results on screen at a CENTUM VP integrated production control system operator terminal or at a standard PC. MIRROR PLANT also has an alarm function that can alert operators to potential problems. As such, the MIRROR PLANT solution can help our customers operate their plants safely and efficiently while maintaining product quality.
2. Consulting and engineering services
Yokogawa offers consulting and engineering services for building the simulation models that are key to MIRROR PLANT’s effectiveness. Yokogawa’s experienced process control engineers provide our customers these services. The simulation models used in MIRROR PLANT are built based not on statistical data from plant operations, but on physical laws. Thus, processes can be theoretically verified, and the simulator can be used for a broad range of applications such as identifying problems in a process. The optimum operating conditions can then be identified before making changes to items such as the production volume or the feed material composition. Based on MIRROR PLANT, Yokogawa offers these services to help its customers optimize their plant operations.
3. Proven effectiveness
A field test of MIRROR PLANT was conducted from 2011 to 2013 at a plant of Mitsui Chemicals, Inc., and the results showed that it efficiently stabilized and optimized the operation of a distillation tower. As a result, MIRROR PLANT won the Technology Award from the Society of Instrument and Control Engineers (SICE), which commended this innovative technology for boosting plant productivity and safety.
MIRROR PLANT was developed based on the OmegaLand integrated dynamic simulation environment and its core technology, the Visual Modeler plant simulator. OmegaLand and Visual Modeler are software packages that were developed by Yokogawa’s subsidiary, Omega Simulation Co., Ltd. OmegaLand builds virtual plants and simulates their operation under conditions that are close to the actual state. These are used for plant operator training and process design in the oil & gas and petrochemical industries.
