标准范围
IEC 61784-3-3:20 16规定了基于IEC 61784-1、IEC 61784-2(CP 3/1、CP 3/2、CP 3/4、CP 3/5和CP 3/6)的CPF 3和IEC 61158类型3和10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。与上一版相比,此版本包括以下重大技术变更:-从该协议版本中移除传统V1模式;-防止可能的环回的协议扩展(LP扩展);-为具有大量参与者的安全网络保留SIL3的协议扩展(XP扩展)和随后的新F-参数“F_CRC_Seed”;-除了先前的连续号码之外,引入随机和不相交的基于代号的监控号码(MNR);-通道颗粒钝化和随后的新F参数“F_Passivation”的规定;-由于新的F参数而导致的GSD扩展;-根据IEC 61158中的CP3系列的符号(例如IO控制器);-附加诊断消息类型;-各种错误更正和错别字修复;-更新了参考书目中的文件。
IEC 61784-3-3:2016 specifies a safety communication layer (services and protocol) based on CPF 3 of IEC 61784-1, IEC 61784-2 (CP 3/1, CP 3/2, CP 3/4, CP 3/5 and CP 3/6) and IEC 61158 Types 3 and 10. 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. This edition includes the following significant technical changes with respect to the previous edition:
- Legacy V1-mode removed from this protocol edition;
- Protocol extensions to protect against possible loopbacks (LP extensions);
- Protocol extensions to keep SIL3 for safety networks with large numbers of participants (XP extensions) and subsequent new F-Parameter "F_CRC_Seed";
- Introduction of random and disjoint Codename based MonitoringNumbers (MNR) besides to the previous Consecutive Numbers;
- Provisions for Channel Granular Passivation and subsequent new F-Parameter "F_Passivation";
- GSD extensions due to new F-Parameters;
- Notations according to the CP3 family in IEC 61158 (e.g. IO Controller);
- Additional diagnosis message types;
- Diverse error corrections and fixes of typos;
- Updated documents in bibliography.
