标准范围

IEC 61784 3-2:20 16规定了基于IEC 61784-1、IEC 61784-2和IEC 61158类型2的CPF 2的安全通信层（服务和协议）。它确定了IEC 61784-3中定义的与该安全通信层相关的功能安全通信原则。该安全通信层仅用于在安全设备中实现。这第三版取消并取代了2010年出版的第二版。本版构成技术修订版。与上一版本相比的主要更改如下（在本文档中以黄色突出显示）:-增加了FSCP 2/1与CP 16/3结合使用的详细要求（参见4.1、6.4.3、6.5.3、8.2、8.13和其他参考文献，当提及CPF 2网络时）；-在8中定义了用于EDS文件定义的安全性的对象类部分关键字。10.2.1;-7.1.2.1中关于安全性CRC概述的新章节和7.4中关于EF格式的滚动计数的新章节；-对9.5.2中PFH计算的修正；-从MACID更改为NodeID，作为对网络标识符的一般引用。

IEC 61784 3-2:2016 specifies a safety communication layer (services and protocol) based on CPF 2 of IEC 61784-1, IEC 61784-2 and IEC 61158 Type 2. It identifies the principles for functional safety communications defined in IEC 61784-3 that are relevant for this safety communication layer. This safety communication layer is intended for implementation in safety devices only. This third edition cancels and replaces the second edition published in 2010. This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below (and highlighted in yellow in this document):
- Added detailed requirements for use of FSCP 2/1 in conjunction with CP 16/3 (see 4.1, 6.4.3, 6.5.3, 8.2, 8.13, and miscellaneous references when referencing CPF 2 networks);
- Defined object class section keywords for safety to EDS file definition in 8.10.2.1;
- New sections on safety CRC overview in 7.1.2.1 and Rollover counts for EF format in 7.4;
- Corrections to PFH calculations in 9.5.2;
- Change from MACID to NodeID as general reference to network identifier.
