新一代开放型PLC的研究

Research on a New Generation of Open Architecture PLC

本文介绍了一种以IPC为核心的，符合IEC1131国际标准的，全新一代开放型体系结构的PLC。它不仅克服了传统PLC互不兼容的缺点，并且将PLC的基本功能与SFC（SequentialFunctionChart）自动编程，监视和故障诊断专家系统的功能结合成一整体。为用户提供了更友好的人机界面。明显提高了系统的性能和效率，提高了可靠性，降低了成本，方便了维修。

A new open-architecture PLC based on IPC is proposed in this paper. I tintegrates the basic function of PLC, SFC auto programming, system monitoring and faultdiagnosis into a single PLC based on IPC with friendly. By obeying the IEC1131 internationalstandard, it also avoids the problem of the conventional PLC. This Kind of PLC has the advantageof higher reliability, lower cost and is easy to maintain. It greatly improves the performance,flexibility and efficiency of the system,and provides more friendly operator interface.
