Fieldbus Specification for Wireless Fieldbus Foundation Releases Specification for Wireless Devices in ROM Systems

The advance of wireless devices in the process industry in inevitable: Now the Fieldbus Foundation has released the final specification for integration of ISA100.11a wireless field devices into its Foundation for Remote Operations Management (ROM) technology. The new standard shall help to use multiple wired and wireless protocols simultaneously...

Austin/Texas – The new Foundation for ROM shall extend the capabilities of Foundation Fieldbus systems in remote and hazardous locations, the organisation explained. Key features are a a true predictive and proactive maintenance strategy for remote assets that could not previously support one as well as a unified digital infrastructure for asset management in applications ranging from tank farms and terminals to pipelines, offshore platforms, and even OEM skids.

Wireless Technology with Leading Network Protocols

With this release, the Fieldbus Foundation has finalized the remote I/O, wired HART and WirelessHART, and ISA100.11a portions of the Foundation for ROM specification. The technology integrates these protocols, along with H1 fieldbus, into the FOUNDATION fieldbus managed infrastructure. Specifications for Modbus communications are in development that will enable Modbus devices such as wellhead flow meters and submersible pump controllers to be integrated in a similar way.

Final Specification for ISA100.11a Device Integration Released

The new Foundation specification means that end users will be able to manage their ISA100.11a wireless devices just like Foundation fieldbus devices within an existing fieldbus infrastructure. The new specification includes parameters for ISA100.11a transducer blocks, providing the block application objects into which ISA100.11a variables may be mapped for access by other fieldbus devices. The transducer blocks also provide a mechanism to pass data to and from ISA100.11a devices directly from configuration or asset management hosts.

The Fieldbus Foundation's director of technology development, Dave Glanzer, commented, "Our new specification will benefit end users who need to be able to interface ISA100.11a wireless devices to improve their integration with a control system and field devices. It also provides a networked method for an asset-managing host to access a large set of ISA100.11a devices for configuration and maintenance purposes.
