INTECH MARCH/APRIL 2018 29 SYSTEM INTEGRATION The next chapter in the wireless sto ry is scale. The deployment of ISA100 Wireless for 100 percent site coverage at Alcoa is a large-scale wire- less infrastructure deployment and sets the stage for ubiquitous sensing. In another use case, hundreds and thousands of steam trap monitors are currently being deployed at hydro - carbon processing sites using ISA100 Wireless networks. Steam trap moni - tors offer huge ROI, with typical pay- back in 12 months or less due to device efficiency improvements and reduc - tions in device maintenance costs. We expect to have a real-world story de - scribing lessons learned and benefits realized by this time next year. Quietly growing The 2017 ON World Market Report on industrial wireless sensor networks and the Industrial Internet of Things (IIoT) said that ISA100 Wireless is the fastest growing industrial wireless mesh stan- dard, with adoption increasing at 2.5 times the pace of its leading competi- tor. ISA100 Wireless adoption increased 67 percent over the past two years. Major factors driving ISA100 Wireless adoption over its competition include: l flexible time scheduling l software and protocol tunneling l support for flexible topologies, such as star and mesh These features are especially impor- tant for growing wireless applications, such as gas detection, steam trap mon - itoring, and oil and gas well site remote monitoring. Suppliers had reduced cost and faster time to market for wireless product of- ferings using ISA100 Wireless. Complex products with proprietary protocols can be converted economically with the pro- tocol tunneling and object technology features of ISA100 Wireless. For example, the GE Bentley Nevada vibration moni- toring application was implemented us- ing protocol tunneling, and the host ap- plications remained unchanged. Further, the ISA100 Wireless network capabilities allow the large wave form data sets to be transmitted through native ISA100 Wire- less networks. Enraf radar level gauges were similarly converted; these instru- ments also use large wave form data sets. Novel uses of ISA100 Wireless in- clude a specialized ISA100 Wireless network and wireless handheld con- trol for loading crane applications at shipping ports, as well as use of ISA100 Wireless networks onboard commu- nication satellites. Native IPv6 to the device provides the advanced features of the updated IP protocol as well as future-proofing device addressing. Further, recent engineering graduates are typically familiar with open stan - dards-based IP addressing schemes, making the technology uptake easier. Staying relevant for process indu stry Although ISA100 Wireless is useful out- side of the traditional process industry, Wireless Compliance Institute mem- bers remain focused on their process industry roots. Through an agreement gateways are appearing in smaller, less expensive packaging and moving into adjacent industry verticals. Shoebox- sized gateways are now appearing in packaging the size of a deck of cards. WCI is investing in improvements to the ISA100 Wireless implementation specification, third-party technology of- ferings, and the supporting technology ecosystem to benefit existing and new suppliers. In midyear 2018, WCI will an- nounce the availability date of an offer- ing that significantly reduces the cost and time to convert wired devices to wireless. Open standards and multivendor in- teroperability continue to be the foun- dation of ISA100 Wireless. In addition to standardized device testing and cer- tification, WCI conducts interoperabil- ity trials one or two times per year to ensure that the ISA100 Wireless brand promise of interoperability works in the Open standards and multivendor interoperability continue to be the foundation of ISA100 Wireless. with Fieldbus Foundation (now FCG), WCI standardized on device descrip- tion (DD) specifications based on the Fieldbus Foundation specifications, thus ensuring device compatibility with host control systems. WCI formed a collaboration agree- ment with FDT, and in 2014 jointly an- nounced availability of an ISA100 Wire- less annex to make FDT device type managers useable by ISA100 Wireless devices. Through collaboration with FCG, WCI developed an ISA100 Wire - less annex for the FDI platform, an important process industry initiative. WCI customers can now generate FDI DD specifications through the ISA100 Wireless FDI annex or through FDT technology, whichever they prefer. What is next? ISA100 WCI suppliers continue to ex- pand the portfolio of ISA100 Wireless products and applications that support traditional process industry needs. How- ever, there is also expansion into new applications that require high reliabil- ity and the advanced features of ISA100 Wireless. While still robust, sensors and real world. These are fun events (see the 2017 Taipei summary on the website) that generate goodwill among members and provide opportunities for business networking. WCI gains valuable feed- back from ISA100 Wireless suppliers at these events, which helps to guide the WCI technology road map. n ABOUT THE AUTHOR Andre Ristaino (aristaino@isa.org) is man- aging director of the ISA Automation Stan- dards Compliance Institute in Research Triangle Park, N.C.
