ISA subcommittee heads for ‘single standard’

02 June 2008

Options for convergence of the ISA100.11a and WirelessHART standards are to be discussed following the creation of a subcommittee by the ISA100 Standards Committee. The move is set to bolster the committee’s attempts to develop universal industrial wireless standards.

The subcommittee aims to contrast and compare the technology within the ISA100.11a and WirelessHART standards, building on the experiences gained with industrial applications of both standards, with an ultimate goal of merging the best of both standards into a single converged subsequent release of the ISA standard.

Paul Sereiko of Airsprite was invited, along with Dick Caro of CMC Associates, to serve as co-chair of the new subcommittee.

He said its creation was an important development. ‘It furthers the mission of ISA100 to embrace relevant industrial wireless standards and serves the expressed needs of the end user community.

‘On behalf of end users, I believe I can safely state that our ultimate goal is to have a single industry standard for process applications,’ said ISA 100 End User Working Group co-chair, Jim Reizner of Proctor and Gamble.

‘We are pleased that a path is developing to achieve that goal and that interim steps for achieving interoperable practical experience with both standards have been identified,’ Reizner added.

Reizner led a team of end users, including Pat Schweitzer of ExxonMobil, Herman Storey of Shell Global Solutions, and others, which stimulated the formation of the subcommittee.

An early activity of the ISA100 WirelessHART Convergence Subcommittee is to prepare the WirelessHART standard in an ISA standard format by the end of July to facilitate the evaluations.

‘We look forward to the prospects of evaluating WirelessHART for convergence within ISA100 and remain committed to the timely approval of the ISA100.11a standard in 2008,’ said Jose Gutierrez of Emerson Electric Company.

‘We remain committed to the final release of an approved ISA100.11a standard and to the subsequent collaborative evaluation of WirelessHART within the ISA100 family of universal wireless standards,’ said Dave Kaufman of Honeywell International.

Schweitzer, who serves as co-chair of the ISA100 committee along with Wayne Manges of Oak Ridge National Laboratories, said adoption of the ISA100.11a standard in 2008 would be an important step for the committee and industry.

‘This new subcommittee is the next logical step to helping industry fully achieve the significant benefits of wireless technology,’ he said.
