In an joint open letter to “Customers, Suppliers, Media and Organizations in the Automation Industry”, four prominent process automation companies have emphasized their belief in the relevance and applicability of the WirelessHART standard, which was released as part of the HART 7 specification. Edited extracts are provided below:
“We would like to take this opportunity to share with you our enthusiastic belief that WirelessHART is the solution that will help customers enjoy the benefits of wireless today and for years to follow.
“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.
“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.
“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.
“The HCF technology is also available for license to nonmembers. Following its completed work on the WirelessHART standard in September 2007, the HCF offered ISA an unrestricted, royalty-free copyright license, allowing the ISA100 committee access to the WirelessHART standard. “All of these factors and more give us great confidence that the WirelessHART standard will fully meet the needs of the process industries for a wireless field device network – now, and for many years to come.
“We are all delivering WirelessHART products this year and fully expect other HART member companies to do the same. Customers are gaining benefits today, and interest from the industry is extremely high. We hope you will soon realize the benefits too!”
