IEC 61158-3-14:20 14定义了在现场总线参考模型的应用层和数据链路层之间的边界处向类型14现场总线应用层提供的服务，以及在现场总线参考模型的数据链路层和系统管理之间的边界处向系统管理提供的服务。这第三版取消并取代了2010年出版的第二版。它构成技术修订。主要变化有: -更新通信模型； -更新5.4.2中FRT应用的DL-管理服务的原语和参数； -纠正编辑错误； -更新所有符合性类别的要求； -更新所有一致性服务的要求。

IEC 61158-3-14:2014 defines the services provided to the Type 14 fieldbus application layer at the boundary between the application and data-link layers of the fieldbus reference model and systems management at the boundary between the data-link layer and systems management of the fieldbus reference model. This third edition cancels and replaces the second edition published in 2010. It constitutes a technical revision. The main changes are:
- update the Communication model;
- update the primitives and parameters of the DL-management service for FRT applications in 5.4.2;
