摘要

在现场总线自动化系统中，实时行为的正确性不仅取决于设备内部的处理和进程调度，还取决于设备间交换过程变量信息的通信。本文提出了一种评估工业通信协议时序特性的工具。它可以根据影响通信的可变条件监视拟议通信的运行时时序需求，并以图形方式显示结果验证的时间特征。两个案例研究，一个评估基金会现场总线协议的实时特性，另一个评估所使用的CSMA媒体访问协议的时序特性，以验证所提出的工具的特性。

Tool support for evaluating temporal characteristics of industrial protocols

In fieldbus automation systems, the correctness of the real time behavior depends not only on the intra-device processing and process scheduling, but also on the inter-device communication that exchanges process variables information. The article presents a tool to evaluate temporal characteristics of industrial communication protocols. It can monitor runtime timing requirements of proposed communication, according to variable conditions affecting the communication, and present graphically time characteristics of the resulting validation. Two case studies, one evaluating the real time characteristics of the Foundation Fieldbus protocol and another one evaluating timing characteristics of the CSMA medium access protocol used are presented in order to validate the features of the presented tool.
