PLC软冗余在氮气连续供应自控系统中的研究与应用

摘要

This paper introduces a low-cost PLC redundancy system-the application of Siemens PLC software redundancy in acontinuous supply of N2. The paper also provides a detailed description and illustration for the composition of the system and the software configuration, finally it introduces the design and realization of the software redundancy programming.%介绍一套低成本的PLC冗余系统——西门子PLC软冗余在氮气连续供应中的实现,对系统的构成、PLC的软冗余组态及其软冗余的编程等进行详细的介绍和说明.实际应用说明本控制系统能够达到期望的控制要求.
