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。 [外文原描述]： IEC 61784-1:2010 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 third edition cancels and replaces the second edition published in 2007. This edition constitutes a technical revision. The main changes with respect to the previous edition are: - update of the dated references to the IEC 61158 series, to IEC 61784-2, to the IEC 61784-3 series, to the IEC 61784-5 series and to IEC 61918 throughout the document; - update of the titles of the referenced documents and references if needed; - update of selection tables for CPF 1, CPF 2, CPF 5 and CPF 8. This bilingual version published in 2011-12, corresponds to the English version published in 2010-07.
