The Application of the Way for PLC to Treat Analog Quantity in the Detecting of the Machine Tool Parameter

Zhu Chao-kuan

Abstract

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.
