Wireless standard moves to ballot stage
The ISA committee has issued the ISA100.11a draft open standard for initial work group balloting, which is the first step in the consensus based approval process for the standard. The standard is focused on process industry applications without excluding factory automation. The standard will use a single application layer, providing both native and tunnelling protocol capability for broad usability, and provide simple, flexible, and scaleable security addressing major industrial threats.
Release 1 of ISA100.11a is intended to provide technology to address non-critical Class 1 to Class 5 applications, such as monitoring. The standard will assure multi-vendor device interoperability, and will include 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 also offer field device meshing and star capability.
The system architecture will include provisions to accommodate alternate radios in future releases, support factory automation applications, support low latency applications, and will not preclude low cost implementations over the life cycle of the intended deployments.
