德州奧斯汀2007年6月22日消息，現場總線基金會宣布FF-5692.0版主機互用性支持測試和程序規定已經面市。新公布的內容包括：更新的基金會現場主機特征，互用性要求定義，測試步驟通向主機測試。主機成功完成了注冊，測試將通過基金會正式的注冊和審定。 　　由現場總線基金會系統整合和維護工作組開發的FF-5692.0版，是基于基金會新主機側面測試和注冊程序基礎之上的組件。現存的主機互用性支持測試（HIST）程序將由主機注冊程序所取代。 　　在基金會現場自動化架構中，主機特征是系統互用性的主關鍵部分。主機特征定義了主機所表現的不同級別，包括61級整合主機，62級訪問主機和63/64椅型主機 　　自動化設備提供商和終端用戶將受益于主機注冊程序。如目前設備注冊過程，主機注冊將鞏固現場總線互用性和系統整合。更新的主機特征規定比現行規定要更容易理解，同時消除了不一致性有利于主機外形特征。 　　現場總線基金會現場總線經理Stephen Mitschke說：“FF-5692.0版主機特征規定加強了測試的步驟和基金會現場總線主機的注冊。更新的主機規定是通過領先設備提供商，主機提供商和終端用戶共同開發的。每一次進步都為檢驗現場總線系統互用性提供了工業領域堅實的解決方案。” 　　由現場總線基金會正在開發的主機測試工具包預定在8月面市。測試包將充許買主在遞交之前進行預測試。工具包與新規定一起應用到主機應用的功能性測試中，同時檢驗主機特征是否合適。主機特征注冊程序（FF-525）將在主機測試工具包面市后下載獲得。 　　更多信息請登錄網址： （http://www.fieldbus.org/images/stories/newsroom/downloads/faq569_61907.pdf） original text [COLOR=#708090]Fieldbus Foundation updates Host Profile Spec 　　AUSTIN, Texas, June 22, 2007 - The Fieldbus Foundation announced the availability of the FF-569 Version 2.0 Host Interoperability Support Test Profile and Procedures Specification. The new release includes updated FOUNDATION fieldbus host profiles and features defining interoperability requirements and test procedures leading to host registration. Hosts successfully completing registration testing will be authorized to bear the foundation‘s official product registration symbol. 　　Developed by the Fieldbus Foundation‘s System Integration and Maintenance （SIM） Working Group, FF-569 Version 2.0 is the basis for the foundation‘s new Host Profile Test & Registration Program. The existing Host Interoperability Support Test （HIST） program will be superseded by the host registration program. 　　In the FOUNDATION fieldbus automation infrastructure, host profiles are a key to system interoperability. The profiles define required host features for different classes of hosts, including Class 61 Integrated Hosts, Class 62 Visitor Hosts, and Class 63/64 Bench Hosts. 　　Both automation suppliers and end users will benefit from host registration. Like the current device registration process, host registration will strengthen fieldbus interoperability and system integration. The updated host profile specification is easier to understand than current specifications, and eliminates inconsistent features in favor of defined host profiles. 　　Fieldbus Foundation Manager-Fieldbus Products, Stephen Mitschke, said, "The FF-569 Version 2.0 Host Profile Specification enhances the procedures for testing and enables registering FOUNDATION fieldbus hosts. The updated host profile specifications were developed through the cooperation of leading device suppliers, host vendors, and end users. Every effort has been made to provide the industry with a robust solution for verifying fieldbus system interoperability." 　　The Fieldbus Foundation is in the process of developing a Host Test Kit that is scheduled for release in August. The test kit will allow vendors to pre-test their host before submitting it for testing and registration by the foundation. The kit works in conjunction with the new specification to apply functional testing to host applications, and to verify that host features are properly implemented. The Host Profile Registration Process （FF-525） will be available for download after the release of the Host Test Kit. 　　For additional information, please review the Frequently Asked Questions document available on the foundation‘s website （http://www.fieldbus.org/images/stories/newsroom/downloads/faq569_61907.pdf）[/COLOR]
