Automation Suppliers Show Support for Interoperable Wireless Standard
May 2, 2008
WirelessHART is the solution that will help processors enjoy the benefits of wireless control strategies today and for years to come, says four leading Hart-based process control and automation products.
A multi-vendor, interoperable wireless standard, WirelessHART was defined specifically for the requirements of process field device networks by members of the Hart Communications Foundation (HCF). The companies comprising HCF membership -- among them, ABB, Emerson Process Management, Endress+Hauser and Siemens -- represent more than 90 percent of the field devices and control systems sold in the industry today.
"As automation suppliers, we have a responsibility to innovate and deliver technologies that help customers realize new levels of performance, while ensuring open, interoperable technology platforms," said the companies in a joint release. "This requires a dedicated focus on customer needs, and a spirit of collaboration to co-develop these game-changing, yet easily accessible technologies. Our customers expect no less. WirelessHART is just such a technology."
According to the HCF, the team that developed the interoperable, multi-vendor standard took great effort to ensure it would provide a solid platform for the future. The standard was designed and field proven for reliability, power consumption, security, expandability and other factors against many use cases, including wireless-based control.
Backward compatibility with the Hart “user layer” allows transparent adaptation of Hart-compatible control systems and configuration tools to integrate new wireless networks and their devices, as well as continued use of proven configuration and system-integration work practices.
To address interoperability as process control solutions evolve, in September 2007, the Fieldbus Foundation, Profibus Nutzerorganisation and HCF formed a "wireless cooperation team" to develop a specification for a common interface to a wireless gateway, further protecting users' investments in technology and work practices.
