IIC consortium testbeds provide real-world IIoT deliverables

Testbeds enable members to think through innovations, test new applications, processes, products, services and business models to ascertain their usefulness and viability before taking them to market.

THE FOLLOWING IIC TESTBEDS have shared important first results.

The Manufacturing Quality Management testbed is focused on improving manufacturing quality by retrofitting outdated factories using modern sensory networks and analytic technologies.

Track & Trace Testbed: Initially formed to trace process tools, the team deployed sensors that provided information about the location of tools and assets in use. It was expanded from tools to logistics equipment and forklifts.

Results: The testbed identified standardization opportunities in localization-technology interfaces, tightening-tool interfaces, enterprise-system interfaces, data models, data communications and device management. It also identified reusable interfaces that opened the solution to components from different vendors.

Time Sensitive Networking Testbed: Time-sensitive networking (TSN) enhances Ethernet to bring more deterministic capabilities to the network, including time synchronization, which schedules traffic flows and manages central automated system configuration. This testbed applies TSN technology in a manufacturing system with a wide range of automation and control vendors.

Results: The testbed deployed early-phase IEEE 802.1 and IEEE 802 Ethernet standards. The testbed will improve upon those standards, making the use of TSN where it can improve efficiency, such as manufacturing and energy.

Manufacturing Quality Management Testbed: This testbed will improve manufacturing quality by retrofitting outdated factories using modern sensory networks and analytic technologies. The initial success was shown using the welding section of the air conditioner production line in a factory.

Results: In March 2017, an optimized noise detection analytic engine was proven to help reduce the false detection rate by 45%. In June 2017, the analytic engine for noise detection was integrated into the production line and the accuracy of pass/fail detection was dramatically improved.

Communication and Control for Microgrid Applications Testbed: A microgrid combines generation and storage into a local power system. It allows more reliable use of renewable sources like solar or wind power in conjunction with, or even isolated from, the rest of the power grid. Near-term uses are for limited areas, such as a campus, corporation, hospital, factory or residential area. Someday, the microgrid architecture will enable deeper use of renewables throughout the main grid.

Results: This testbed proves the viability of a real-time, securely distributed control architecture for real-world microgrid applications. It leverages an Industrial Internet Reference Architecture (IIRA) pattern called the "layered databus" that federates multiple connectivity domains into a larger system. The testbed implemented the pattern with the Data Distribution Service (DDS) standard as explained in the Industrial Internet Connectivity Framework (IICF) guidance. The testbed validated both the pattern and its implementation, contributing to the Open Field Message Bus (OpenFMB) design, now a power industry standard.

INFINITE Testbed: The INternational Future INdustrial Internet TEstbed (INFINITE) uses software-defined networking to create virtual domains so that multiple virtual domains can run securely on a single physical network.

Results: This testbed enabled intelligent route planning for ambulances to improve response times, leading to better pre-hospital emergency care experiences and outcomes for patients. It also led to improved safety and effectiveness of rst responders in emergency situations, especially in harsh environments. A third use case enabled detection of anomalies or fraudulent behavior within the power grid through machine learning algorithms.

Condition Monitoring and Predictive Maintenance Testbed: This testbed provides insight into the health of critical assets. It leverages advanced sensors that automatically predict equipment failure and notifies a person or system so that pro-active steps can avoid equipment damage and downtime.

Results: This testbed demonstrated how to make older assets smart, collecting asset health data from four pump/motor skids used to pump chilled water from an HVAC system.

Smart Factory Web Testbed: This testbed networks a web of smart factories to improve order fulfillment by aligning capacity across production sites.

Results: Factory assets can be registered and searched for in the Smart Factory Web (SFW) portal. IEC standards OPC UA and AutomationML are used to achieve semantic interoperability and are applied to exchange information between engineering tools.

The IIC reviews testbed proposals to identify goals, value, potential partners and commercial viability of each testbed. The testbeds must offer a solid business case and have relevance to IIC IIoT frameworks to help members develop IIoT systems more rapidly.
