This paper introduces the framework of the PROFIBUS/DP networked control system based on the distributed I/O model.

本文以分布式I/O控制系统为模型介绍基于PROFIBUS/DP网络通讯的控制系统架构，阐述了PROFIBUS/ DP控制系统的软，硬件设计思想及在轿车座椅装配线的具体应用。

However, the errors are usually relatively high, even leading to unreliable results, because many approximations and assumptions were involved in J-O model.

由于J -O模型涉及许多近似和假设，计算结果误差较大，可能导致结果不可靠。
