Introduction - Facilitators Teja Kuruganti –Oak Ridge National Laboratory –Background: 10 years of experience in wireless sensor networks particularly in harsh environments, communications modeling, applications of wireless sensors for energy efficiency improvements –Participated in ISA 100 activities –Current interests: Next generation wireless technologies for secure communication networks for electric grid, cybersecurity of communications in electric grid, control over communication networks, channel modeling in harsh environments Dan Sexton –GE Global Research –Background: 33 years of industry experience in wireless sensors, analog and digital design, system design –Co-chair ISA100.11a – Wireless Industrial Sensor Networks –Current Interests: Multi-industry wireless sensor networks, wireless interface standards that are vendor agnostic and help to proliferate the use of wireless technologies where they can offer value for reduced installation costs and open up new applications spaces Wayne Manges –Oak Ridge National Laboratory –Background: 34 years of experience in communications, control systems, systems integration, and standards development –Co-chair ISA100 – Wireless Industrial Sensor Networks –Current Interests: Standards development for introduction of next-generation wireless networks in to industry (process, manufacturing) and smart grid, trustworthiness of wireless sensors in harsh industrial applications, interoperability of multi-vendor wireless sensors networks

ISA107.4 Scope The Subcommittee’s focus is to define scalable architectures, system components, and protocols that allow secure reliable wireless connectivity for test cell based turbine engine measurements. The results of this Subcommittee may serve as a basis for future on-wing engine health monitoring or control systems. This subcommittee will leverage the efforts of existing committees (e.g. ISA84, ISA99, ISA100) and contribute to these committees as necessary. Scope developed at Subcommittee’s first face-to-face meeting at Automation Week 2011, St. Louis

ISA Timeline SP107.4 Subcommittee meeting at PIWG meeting on November 9 th 2011 in Chatsworth, CA –Establish goals like future proof, vendor agnostic, make sure we aren’t excluding approaches (inclusivity). –Harmonize Subcommittee’s Goals with DO #1 : Identification of Current and Future Sensor and Instrumentation Technology –Goals agreed to in tcon’s before 11/9 and requirements. Present goals and start of requirements Define requirements by 1/1/2012 RFI issue 2/15/2012 Intent to respond by 3/1/2012 RFI actual response 4/15/2012 RFI responders make presentations at PIWG spring meeting – 20 minute presentations, with 10 minute Q/A

Standard vs. Proprietary Solutions Proprietary Pros –Single point of contact –Customized/targeted solutions –Vendor relationship Cons –Scalability –Interoperability –Very limited suppliers –Life-cycle cost Standard Pros –Multi-vendor solutions –Low-cost –Interoperability –Extensive support –Non-traditional suppliers –Flexible Cons –Consensus-based activity –Intense user participation required –Homogenized outcome

What is the Purpose of this Subcommittee Where shall the wireless interfaces need to be? –Define the surrounding environment (inside or outside engine) –Identify the radio frequency (RF) environment Multi-vendor interoperability support for various applications on the test stand –System integration support for critical and non-critical measurements –Common application interfaces –Common network management –Enhanced security management Co-existence support –With other network standards – possible –Other proprietary networks – not addressable

Goals for this meeting Does the wider-community want a standard for wireless instrumentation in turbine test stand environments? –PIWG already endorsed the concept What should the standard be from this community perspective? –What problems should be addressed? –What are requirements? –Data delivery requirements to make meaningful observations –List of sensing modalities –Where shall the interfaces need to be to perform observations Recruit people – primarily industry experts (turbine) –Step 1 – define and develop the requirements –Step 2 – understanding what is feasible (technology)
