摘要
介绍利用PLC及其专用的A/D模块,将传感器对物理量转换后的模拟电压信号采集输入到PLC中,然后进行整定变换,并将结果加以运算、显示的一般处理方法,结合机床液压系统压力参数的检测,叙述了处理的详细过程。
The way that the PLC treated analog quantity by using its exclusive A/D module was introduced.For this way,physical quantity signal was converted to analog voltage signal,then it was gathered and input to PLC,and PLC transformed those signal to data,finally those signal data was calculated and displayed.Combining the detecting of machine’s pressure system parameter, the detailed procedure was discussed.
