Pengukuran Kecepatan Putar Motor Berbasis Programmable Logic Controller (PLC) Omron CPM2A dan Komputer

PLC (Programmable Logic Control) is widely used in the industry as the main control unit on production machines. PLC is a set of electronic switches that can be set when to ON and when to OFF in accordance with the laws of logic control has been programmed. One of the advantages of PLC is that it can be used to control machine tools are different just by changing the existing program in the PLC without having to change the hardware. In this research will be designed to drive the motor and read speed of rotation (RPM)
