摘要
通过分析南瑞MB80系统PLC开出模块防误功能以及机组控制开出特点,提出了监控系统机组开出加装监测继电器,或加装开出保护装置以提高机组监控开出防误功能的建议方案,为相关计算机监控系统顺控防误设计和改造提供参考.
By analyzing the error proofing function of PLC output module of NARI MB80 system and the output characteristics of power unit controls,the proposal is put forward that the monitoring Relay and protectiue setting should be installed in the power unit of monitoring system to improve the error proofing function.It provides reference for the relative error proofing design and transformation of computer monitoning system.
