摘要

ControlNet网络被设计为互操作自动化产品的中央通信体系结构。它为控制目的提供快速、确定的计划数据传输，并为同一网络上的配置和内部管理提供非计划的非时间关键消息传递。这是通过将带宽划分为保证在指定的网络更新时间内交付的计划部分和基本上是处理计划流量后剩余时间的非计划部分来实现的。用户为ControlNet提供的一个关键参数是网络更新时间(NUT)。在本文中，我们研究了在控制情况下使用ControlNet网络时的关键参数。给出了仿真结果和结论。

Influence of NUT on Bandwidth Utilization for ControlNet

The ControlNet network is designed to be the central communication architecture for interoperating automation products. It provides fast, deterministic scheduled data transfer for control purposes and unscheduled non–time–critical messaging for configuration and house–keeping on the same network. This is accomplished by partitioning the bandwidth into a scheduled portion that is guaranteed to be delivered within a specified Network Update Time and an unscheduled portion that is essentially the time remaining after the scheduled traffic is handled. A critical user-supplied parameter for ControlNet is the Network Update Time or NUT. In this article, we studied the critical parameter of the ControlNet network when used in a control situation. Simulation results and conclusions are presented.
