摘要
辅机程控系统通过集中上位机、PLC、远程I/O机柜间的光缆冗余通讯,合理的PLC软件设计,形象的上位机监控界面,实现了辅机系统设备运行自动化。并可实现与SIS(厂级实时信息管理系统)系统的联网。
The auxiliary prograrn control system is an important part of thermal power plants. Through the centralized host computer, PLC, remote I / O cabinet cable redundant communications, reasonable PLC software design and image-on-bit control interface, the automation of auxiliary system is achieved. The system can be connected with the SIS （plant-level real-time information management system） system.
