2013 is not only the 10thanniversary ofAutomation World; it also marks the 20thanniversary of the哈特通信基金会, developers of the HART communication protocol and WirelessHART technology. HART is a global standard for sending and receiving digital information across analog wires between smart devices and control or monitoring system. More specifically, HART is a bi-directional communication protocol that provides data access between intelligent field instruments and host systems.
什么时候Automation World最近出版了它的E-Book Special Report on Networks,we wanted to provide a solid overview of industrial networking technology for users in the continuous process, batch and discrete manufacturing industries that went beyond单个文章and newproduct announcementson the topic. Regarding wireless communications, we included information from the HART Communications Foundation as well as from theISA100 Wireless Compliance Institute, which provides support for vendors designing products to ISA100.11a, an industrial wireless sensor networking standard that is competing with WirelessHart as an enabler of smart instrumentation.
该电子书被广泛接受为可靠的概述，但还有很多话要说。我从Hart和FieldBus Technology的总监Martin Zielinski听到了Emerson Process Management,and he wanted to make sure users knew some additional information.
“我刚读过你的文章,“无线协议s for the Process Industries”, that appeared in your E-Book Special Report, “Networks: Wired and Wireless”. Your article accurately points out the philosophical differences between WirelessHART® and ISA100.11a. WirelessHART is all about making WirelessHART easy and straightforward for the end user to deploy. ISA100.11a is all about flexibility and forcing end users to make choices about a communication technology—choices that can lead to configuration mistakes and end user frustration. It is clear that a device utilizing ISA100.11a will not interoperate with WirelessHART based devices,” Zielinski says.
Zielinski补充说：“虽然暗示，但您没有明确说明在无线通信协议中，有多个供应商的无线产品确实相互互操作。”“哈特通讯基金会发布了一份清单WirelessHART registered productson their web site. Please point this fact out to your readers.”
AtAutomation World, we’re happy to point out such links for further information and discussion. For users who what to find out additional information or ask questions of WirelessHART users and product suppliers, Zielinski notes that the HART Communication Foundation hosts aforumfor the entire HART protocol, of which WirelessHART is a part. That forum can be found by clicking the “Advance Search” button toward the upper right hand corner of the foundation’s web page and searching for WirelessHART topics. Readers are also welcome to leave comments here to continue the discussion.
Tomorrow I’ll post information that developers of the ISA100 standard would like users to know.
