摘要
通过对PLC实现液位多段控制的设定、显示和报警,克服了由于硬件电器连接导致系统可靠性差的不足。该控制系统具有投资少成本低,不仅自动化程度高,而且还具有在线修改程序的功能,大大提高了控制系统的灵活性和可靠性。
The PLC is used to implement the Setting, demonstration and alarming of multistage liquid level controlling. It overcomes the poor reliablity of the system deficiency. The controlling system has low cost, high automatization degree, and the function of program modification online, and it greatly promotes the flexibility and reliability of the controlling system.
