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 107.4 Timeline
• SP107.4 Subcommittee meeting at PIWG meeting on
November 9th 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)
