基于高速以太网的基金会现场总线功能块应用进程模态分析

Analysis on mode and parameter status of function block application process in foundation fieldbus based on high speed Ethernet

介绍了基金会现场总线中高速以太网(HSE)功能块的参数状态和工作模式的基本结构,总结了参数状态传播和工作模式切换的基本规则,并且以液体温度控制系统的两种典型的控制方案为例,分析了其中功能块的工作模式切换和参数状态传递的具体方法。

The basic architecture and the transition rules of HSE function block mode and parameter status are introduced first in this paper.Then,based on the analysis of typical control strategies in liquid-temperature control system,a concrete transition method of mode and parameter status in function blocks is present in detail.
