标准摘要
[中文适用范围]： IEC 61784 的这一部分定义了一组主要基于 IEC 61158 系列的协议特定通信配置文件，用于工厂制造和过程控制中涉及通信的设备设计。每个配置文件都选择设备上的通信协议栈的规范。它包含应用程序层所需的最小服务集以及通过引用定义的中间层中的选项规范。如果不包括应用层，则指定数据链路层所需的最小服务集。每个通信配置文件系列或关联的配置文件中都给出了对协议特定类型的适当引用。注：所有配置文件均基于 IEC 发布的标准或标准草案或国际标准，或者来自其他标准机构或开放标准流程制定的标准或国际标准。 [外文原描述]： IEC 61784-1:2007 defines a set of protocol specific communication profiles based primarily on the IEC 61158 series, to be used in the design of devices involved in communications in factory manufacturing and process control. Each profile selects specifications for the communications protocol stack at a device. It contains a minimal set of required services at the Application Layer and specification of options in intermediate layers defined through references. If no Application Layer is included, then a minimal set of required services at the Data-link layer is specified. The appropriate references to the protocol specific types are given in each communication profile family or associated profiles. This bilingual version (2014-12) corresponds to the English version, published in 2007-12. This second edition cancels and replaces IEC 61784 1:2003. This edition of this part constitutes a technical revision. This edition of IEC 61784-1 includes the following significant technical changes from the previous edition: partition of IEC 61158 parts 3, 4 ,5, and 6 of the third edition into multiple parts numbered for example IEC 61158-6-1, 6-2, 6-3,... deletion of the former Type 6 fieldbus in IEC 61158 series and CPF 7 for lack of market relevance; addition of new types of fieldbuses in IEC 61158 series leading to new CPF 8, 9, and 16.
