标准范围

IEC 61158-4-19:20 14规定了用于从一个数据链路用户实体到对等用户实体以及在形成分布式数据链路服务提供商的数据链路实体之间及时传输数据和控制信息的过程，以及用于通过本标准的协议传输数据和控制信息的现场总线DLPDU的结构，以及它们作为物理接口数据单元的表示。本第三版取消并取代2010年出版的第二版，构成技术修订。主要变化有:-基于生产者-消费者模型引入连接；-引入附加机制以实现诸如时间戳和过采样的特征；-改进热插拔和冗余特征；-改进相位切换和错误处理。

IEC 61158-4-19:2014 specifies procedures for the timely transfer of data and control information from one data-link user entity to a peer user entity, and among the data-link entities forming the distributed data-link service provider and the structure of the fieldbus DLPDUs used for the transfer of data and control information by the protocol of this standard, and their representation as physical interface data units. This third edition cancels and replaces the second edition published in 2010 and constitutes a technical revision. The main changes are:
- introducing connections based on a producer-consumer model;
- introducing additional mechanisms to realize features such as timestamping and oversampling;
- improving the hotplug and redundancy features;
- improving the phase switching and the error handling.
