标准摘要
[中文适用范围]: IEC 60079 的这一部分包含与现场总线本质安全概念 (FISCO) 一起使用的设备、系统和安装实践的详细信息。它基于曼彻斯特编码、总线供电系统的概念,按照 IEC 61158-2(现场总线安装的物理层标准)设计。 FISCO 设备和系统的结构和安装要求由 IEC 60079-11、IEC 60079-14 和 IEC 60079-25 确定,除非本标准进行了修改。现场总线设备的一部分可以通过 IEC 60079-0 中列出的适合预期使用区域的任何防爆方法进行保护。在这些情况下,本标准的要求仅适用于直接连接到本质安全干线或支线的设备部分。 [外文原描述]: This part of IEC 60079 contains the details of apparatus, systems and installation practice for use with the Fieldbus Intrinsically Safe Concept (FISCO). It is based on the concepts of Manchester encoded, bus powered systems designed in accordance with IEC 61158-2 which is the physical layer standard for Fieldbus installations. The significant change with respect to the first edition is that this standard replaces the FNICO requirements with the requirements of an "ic" FISCO system.
