摘要
文章讨论了PLC在双电源自动投切装置中的应用,阐明了该装置的特点,其可以PLC独立单元运行,也可与当地监控微机通讯构成现场监控子系统,还可通过远程通讯上送远程集控站实现远程监控。
This paper is concerned with application of PLC in dual power source automatic cut-in system. PLC can operate on its own in the system, form an on-site monitoring subsystem with a local monitoring micro- processor, or realize remote monitoring through remote communication with a remote control station.
