摘要
系统是在LM系列PLC的无负压供水标准程序的基础上建立的,实现的功能包括了水泵的自动投切功能、休眠倒泵功能、水泵优先级判断功能、优化的故障处理功能、多时段设定功能、低水位自动保护功能、无负压功能、短信通讯功能以及PLC锁定功能等。整个系统的搭建过程几乎没有对标准程序进行修改,在实现了强大功能的基础上,方便快速地完成了控制系统的搭建。
The system is no negative pressure water standard procedure based on the LM series PLC, functions include automatic switching function of the pump, sleep down the pump function, pump priority judgment function, optimization of fault processing functions. multi-period setting, the low water level automatic protection function, no vacuum function, SMS communication capabilities, as well as PLC lock. The structures of the entire system is almost standard procedure be modified quickly and easily on the basis of powerful control structures.
