基于工业以太网的高速现场总线GSK-Link

High Speed Fieldbus GSK-Link Based on Industrial Ethernet

提出一种基于工业以太网的高速现场总线GSK-Link,它是一种数字化、串行网络的数据总线,用于机床数控系统各组成部分互连通信。GSK-Link修改标准以太网的七层参考模型为三层参考模型,采用环形或线性网络拓扑结构,采用专用的应用层和数据链路层协议,满足高速现场总线的高实时性、高可靠性和精确同步性。

A high-speed fieldbus GSK-Link based on industrial Ethernet is presented in this paper.It is a kind of digital and se- rial network data bus,and used for inerconnect communicating for each component of CNC system.GSK-Link fieldbus mod- ifies the standard Ethernet seven layer reference model for three layer reference model,and adopts annular or linear net- work topology structure,and special application layer and the data Link layer protocol to meet the fieldbus high real-time, high reliability and precision synchronicity.
