    • ARC VIEW OCTOBER 17, 2013 Services Oriented Drives Support Critical Energy Management and Asset Management Applications thanks to IT/OT Convergence By Craig Resnick Keywords Information Technology, Services, Control, Convergence, AC Drives, Energy Management, Asset Management, Internet of Things Overview All manufacturing and processing industries face issues that frequently require the convergence of plant automation and business systems. These issues include environmental and business sustainability, preserving and extending the life of capital assets, increasing asset availability and utilization, maximizing operational effectiveness, reducing fixed costs, minimizing variable costs, and empowering workers. Convergence must include key automation solutions that are often overlooked, such as variable speed AC drives, to fully leverage To address these issues, end users and OEMs alike must move beyond simply automating and integrating production processes to au- the energy management, asset management, tomating and integrating workflows and and overall system performance solutions businesses processes. This requires a conver- that can have the greatest effect on gence that intertwines plant automation productivity and profitability systems with business systems. This convergence moves toward single sys- tems to accomplish tasks, streamline operations, and connect customers and suppliers, all with the goal of lowering costs and adding agility. This convergence should extend from the major plant and enterprise systems used for information technology (IT) to major plant systems (DCS, PAC, PLC, etc.), and ideally, right down to the intelligent devices on the plant or factory floor, such as variable speed AC drives. The latter is especially important to enable industrial facilities to fully leverage the potential of the latest applications for energy management and asset management, as well as optimize overall system performance. In this manner, enterpriselevel energy and asset management applications can take advantage of real- VISION, EXPERIENCE, ANSWERS FOR INDUSTRY
    • ARC View, Page 2 time, online data from intelligent plant floor equipment, such as Ethernetconnected drives, and embedded IT-enabled services to enhance flexibility, capability, and application performance. At least one leading automation supplier has begun to use the term, “services oriented drives,” to describe this new class of intelligent, Ethernetconnected drives that supports the critical need for convergence between information technology and operational technology. This concept is consistent with ARC Advisory Group’s ongoing research into IT/OT convergence, predictive plant asset management (PAM), services oriented architectures (SOA), and the emerging Industrial Internet of Things (IoT). Adding Business-Centric to Applications-Centric For many years, a key requirement of automation suppliers was to design and offer applications-centric solutions able to perform the specific tasks and meet requirements unique to each vertical industry. However, these solutions must also be business-centric; able to help companies reduce their energy consumption, manage their assets, and enhance overall production performance. All devices being deployed, including variable speed AC drives, must address the primary concerns of end users and OEMs alike. These include increasing overall equipment effectiveness (OEE) and decreasing total cost of ownership (TCO). The new generation of services oriented drives can help meet these objectives because it takes into account, not only the drive, but also the complete product chain: motors, drives, and actuators. These requirements are particularly important in energy- and asset-intensive industries such as water & wastewater, oil & gas, mining & metals, and food & beverages. Services Oriented Drives and Energy Management One of the primary market demands for services oriented drives is to help address global energy consumption issues. One place to start is the use of AC drives in pumping systems. Across industries, experts estimate that 25 percent of the electricity consumption comes from pumping systems and 40 percent of the overall lifecycle cost of a pumping system relates to energy. Variable speed AC drives are key devices used to save energy in pumping applications in which approximately 80 percent of the time, pumps typically operate at only 60 percent of their full speed capacity. By reducing the flow to 50 percent, pump energy consumption could be reduced by 88 percent. Services oriented drives manage such system intelligently; hence they ©5774 ARC • 3 Allied Drive • Dedham, MA 02026 USA • 781-471-1000 • ARCweb.com
    • ARC View, Page 3 can be employed in conjunction with energy management systems to optimize energy management. Additional energy savings could be realized if the convergence in technologies made possible by modern services oriented drives were combined with excellence in electrical characteristics. For example, if AC drives with a THDi of ≤ 48 percent were replaced with low harmonic AC drives with a reduced THDi of ≤ 5 percent, users would realize a resulting energy savings of approximately 20 percent in the losses at the associated cables and transformers. Additional advantages of harmonic mitigation would include reduced costs by eliminating the need for oversizing AC distribution equipment and/or by lengthening effective product lifecycles. Energy Monitoring and Embedded Services To optimize energy management, it's critical to be able to monitor and integrate both energy consumption and power dynamics for the entire system (motors/drives/actuators), and to provide the energy management application with additional contextual information, including real-time events, alarms, drifts, and historical data. Appropriate data granularity is required, Embedded services include historians for data logging and recording energy usage, and mobility connectivity so real-time information can be locally or remotely accessible via smart phones, tablets, and plus analytics capabilities to be able to convert all these data into meaningful information so management decision can be made locally at the field or the plant level, or remotely via intranets or the Cloud. other wireless devices. Services oriented drives can provide services to deliver the transparent and instantaneous, prepackaged and ready to use information upon process startup; because these services are embedded, it could help eliminate the need to develop or integrate additional drivesrelated software or applications. Services could include historians for data logging and recording energy usage, and mobility connectivity so real-time information could be accessed locally or remotely via smart phones, tablets, and other wireless devices. Services Oriented Drives and Asset Management More effective asset management is another emerging requirement for today’s asset-intensive industries.

    • ARC View, Page 4 support both schedule-based preventive maintenance and condition-based predictive maintenance. The latter utilizes equipment and process data gathered at the drive level, but typically processed into actionable information remotely at the plant or enterprise system level. Predictive maintenance involves applying condition-based monitoring techniques to collect and analyze asset data to better understand asset performance and perform appropriate maintenance before impending issues can negatively impact plant performance, availability, or safety. Converging with Plantwide Asset Management Systems To support traditional schedule-based, preventive maintenance and enable condition-based, predictive asset management, ARC is seeing a significant increase in the number of process plants and utilities that are implementing plant- and/or enterprise-level asset management systems. Predictive maintenance, in particular, requires the integration of key data and information from AC drives. Ethernet-connected services oriented drives, with their additional embedded capabilities, simplify this integration. For asset management applications, these embedded capabilities can include object-oriented services for process devices (such as drives, motors, and pumps); ISA 88- or ISA 95-related services; and dynamic integrated alarming functionality; plus embedded mobility services to enable remote access to asset information, such as pump state, number of starts, running hours, as well as technical documentation and enriched data. Mobility services also enable remote specialists to provide application, diagnostics, analysis, consulting and other services. Services Oriented Drives and Systems Performance Services oriented drives could also help overcome many systems performance challenges. Built-in Ethernet connectivity could help simplify integration with other plant and enterprise systems and applications to help improve process and asset performance. In terms of scalability, services oriented drive functionality could range from a standalone product to a solution approach in which the drives are integrated with systems, such as telemetry, PACs, PLCs, DCSs and SCADA, as well as devices via servicesoriented architecture (SOA) and open technologies, such as FDT Device Type Managers (FDT DTMs). Clearly, to ensure data security and integrity, appropriate security standards, processes, and standards must be put in place.

    • ARC View, Page 5 and application functionality embedded as services could also support equipment and process optimization schemes. For example, services oriented drives can contribute to merge production and asset management systems along with energy management systems. Thanks to object-oriented services, the user can have a full and accurate vision of the process and hence can take more relevant decisions. Conclusion End users and OEMs need to re-examine their automation and operations management strategies and develop plans to break down the remaining barriers to information visibility, collaboration, Services oriented drives not only play a key and unified plantwide control to enable opera- role in drives optimization, but also in the tional excellence and improve overall business managed convergence between plant floor devices, controllers, energy and asset management systems, and business systems. performance. ARC believes that the concept of services oriented drives with web technology standards, built-in Ethernet connectivity to simplify plant- and enterprise wide integration, built-in intelligence, and key energy management, asset management, and system performance improvement functions embedded as services, plays well with this vision and could represent a key component in the emerging Industrial Internet of Things.
