Research Triangle Park , NC —At a recent ISA-SP100.11a working group meeting in Karlsruhe, Germany, 60 attendees unanimously approved the scope and systems architecture of Release 1 of the draft standard, ISA announced March 30. “ISA-SP100.11a Release 1 will be an open standard for anyone to implement and deploy. The standard will be simple to use, and will be focused on serving process industry applications without excluding factory automation,” said ISA-SP100.11a lead editor and co-chair Pat Kinney of Kinney Consulting LLC.

Release 1 is intended to provide technology to address Class 1 (non-critical) to Class 5 applications, such as monitoring. The standard will ensure multi-vendor device interoperability, and will embrace only 2.4 GHz 802.15.4-2006 radios. The work of the committee will adhere to a comprehensive coexistence strategy, and will use channel hopping to support co-existence and increase reliability. The standard will use a single application layer, providing both native and tunneling protocol capability for broad usability, and provide simple, flexible, and scaleable security addressing major industrial threats. The standard also will offer field device meshing and star capability, ISA says.

A draft standard is expected in October 2007. ISA’s announcement on the progress of ISA-SP100.11a Release 1 contains more information.
