ISA100无线标准:选择太多?

Proponents of the ISA100.11a wireless networking standard say it was designed to enable interoperability and support choice among wireless devices. But can too much flexibility lead to end user frustration? One vendor weighs in.

When自动化世界recently published its电子书有关网络的特别报告,,,,我们希望在连续过程,批处理和离散的制造行业中为用户提供稳固的工业网络技术概述,这些行业超出了individual articlesand new产品公告on the topic.

Ina commenton that E-book, Martin Zielinski, director of HART and Fieldbus Technology for Emerson Process Management, said, “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.”

自动化世界wanted to give someone representing ISA100 Wireless a chance to respond. Honeywell is one of the main vendor advocates for the ISA100.11a protocol; in March it released the availability Release 210 of itsOneWireless Mesh Networkproduct, whose features build on the ISA100.11a standard. The following comes from Soroush Amidi, marketing manager for OneWireless Products and Solutions for Honeywell Process Solutions:

“重要的是要记住用户体验是由产品及其设计定义的,而不是标准。例如,霍尼韦尔(Honeywell)在ISA100无线开发过程中从发病率中吸引了用户。他们的反馈产生了直观的界面,使他们能够在几分钟内部署和配置系统 - 最近进行的调查表明,我们90%的ISA100客户对其无线系统可用性非常满意。

“It is true that ISA100 is very flexible—it is a user-driven standard. More than 400 automation professionals from nearly 250 countries have offered expertise to cooperatively define and design it. The resulting standard has undergone strenuous review and has a diverse base of support.

“ ISA100无线必须是满足用户定义的所有关键要求的全面标准,但是灵活性并不能转化为更复杂的系统。供应商的工作是确保他们以用户友好的方式实施标准。霍尼韦尔在开发其解决方案时对用户体验进行了大量投资,结果得到了回报,正如对我们最近的调查做出回应的满意客户所证明的那样。

“使用ISA100无线的通信协议功能的真实示例是在Honeywell的Onewireless Hart适配器中找到的,该适配器传输了HART数字数据;GE的Nevada的WSIM,该WSIM传输了GE系统1振动分析应用程序使用的振动波形;Gassecure的SIL2批准了通过ISA100无线网络传输Profisafe(功能安全协议)消息的无线气体检测器(行业第一)。

“Users only need to buy the wireless variant of a field instrument from their preferred provider, put it in the field and it will join the ISA100 network. The device will send data using its native protocol (HART, proprietary, ProfiSafe) over the ISA100 network.

“The goal of ISA100 standard, as well as the WirelessHART standard, is to allow interoperability. That’s the whole point of a standard. All these devices mentioned above can communicate with each other and with an ISA100 Wireless Compatible infrastructure. There are many more ISA100 Wireless devices. Visitors to the ISA 100 both in Hannover saw all ISA100 devices communicate with each other. The list of compatible ISA100 Wireless devices is available atwww.isa100wci.org
