摘　　要：为方便分散控制系统的I/O模件地址设置,基于现有的设置方式,提出一种I/O模件地址自动识别的设计方案。该方案可以灵活地加减需要配置的I/O模件数量,方便更换出现故障的I/O模件或模件背板,极大地方便了电厂操作人员。该方案已应用到工程中,运行状况良好。In order to facilitate the I/O module address setting of decentralized control system,a design scheme of I/O module address automatic recognition is proposed based on the existing setting method.The scheme can flexibly add or reduce the number of I/O modules to be configured,and it is convenient to replace the faulty I/O module or module backplane,which is greatly con-venient for the operator of power plant.The scheme has been applied to the project and runs well.
