本文件规定了网络控制系统的通信协议。该协议使用web服务为网络控制提供对等通信。本文档描述了第1层和第2层中的服务。 第1层（物理层）规范描述了MAC子层与物理层的接口。如EN 14908-1所述，第2层（数据链路层）使用IPv4和IPv6协议集成在UDP/IP通信中。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control using web-services. This document describes services in layer 1 and layer 2. The layer 1 (physical layer) specification describes the MAC sub-layer interface to the physical layer. The layer 2 (data link layer), as described in EN 14908-1, is integrated in UDP/IP communication using IPv4 and IPv6 protocols.All current amendments available at time of purchase are included with the purchase of this document.
