基金会现场总线获得安全批准

The specifications are in compliance with the International Electrotechnical Commission (IEC) 61508 standard (functional safety of electrical/electronic/programmable electronic safety-related systems) requirements up to, and including, Safety Integrity Level 3 (SIL 3).

With the TÜV Protocol Type Approval, Foundation Fieldbus technology has been extended to provide a comprehensive solution for Safety Instrumented Systems in a wide range of industrial plant applications. The specifications enable manufacturers to build Foundation Fieldbus devices in compliance with IEC 61508. Third-party test agencies such as TÜV will certify that these devices are suitable for use in safety instrumented systems. End-users will be able to choose devices meeting the requirements of IEC 61511 (Functional Safety: Safety Instrumented Systems for the Process Industry Sector) from multiple suppliers, instead of being restricted to devices designed specifically for a proprietary safety system platform. IEC 61511 is also available as an ANSI/ISA Standard: ANSI/ISA-84.00.01-2004, promulgated by the American National Standards Institute and the Instrumentation, Systems and Automation Society.

The Safety Instrumented System project was initiated by end-users and approved by the Fieldbus Foundation’s board of directors in October 2002. Companies participating in the project include: ABB, BP, Chevron, Cooper Crouse-Hinds GmbH, DuPont, Emerson Process Management, E+H Process Solutions, ExxonMobil, Fieldbus Diagnostics, Fieldbus Inc., Flowserve, HIMA, Hirshmann, Honeywell, ICE-Pros Inc., Invensys/Triconex, Magnetrol, Metso Automation, MTL, Relcom, R&M Industrieservice, Rockwell Automation, Rotork Control Systems, Saudi Aramco, Shell Global Solutions, Smar, Softing, TopWorx, TÜV, Tyco/Westlock and Yokogawa.

开发团队于2003年底实现了其第一主要里程碑，并在整个系统概念批准。该开发团队在2004年3月在荷兰阿姆斯特丹举办的壳牌全球解决方案的会议上会面外部专家，以审查初始规范。评论中的评论得到了解决，管理团队开发了实验室验证测试的顶级项目计划。

During the lab test phase, conducted at the R&M Industrieservice facility in Frankfurt, Germany, each prototype supplier independently implemented the foundation’s safety instrumented systems specifications. In parallel, the test team separately developed test cases and prepared expected test results.

关键系统

According to the Fieldbus Foundation’s director of technology development, David A. Glanzer, extensive laboratory testing and application analysis has verified that the Foundation’s safety instrumented systems technology meets the needs of industrial end-users, who regard these systems as critical to their overall plant operating strategy.

“TÜV型批准将有助于满足加入基础现场总线技术的商业，标准，安全仪表系统产品的不断增长的需求，”Glanzer说。“最终用户现在可以采用基础现场总线的强大诊断，同时保持在SIL 3环境中的保护。现有的H1协议无需更改，以添加安全仪表系统协议扩展，清楚地表明基础技术的综合前瞻性思维设计的价值。“
