基于三菱PLC的三轴自动上下料平台

Three-axis automatic loading and unloading platform based onMitsubishi PLCAbstractThis article mainly discusses the three-axis automatic loading and unloading platformbased on Mitsubishi's PLC model FX5U.Programmable logic controller PLC is a digitaloperation controller with a microprocessor for automatic control.It can load controlinstructions into the memory at any time for storage and execution.Programmable controlleris composed of CPU,instruction and data memory,input /output interface,power supply,digital analog conversion and other functional units.Early programmable logic controllersonly had logic control functions,so they were named programmable logic controllers.Later,with continuous development,these computer modules with simple functions had logiccontrol,timing control,analog control,Various functions such as multi-machinecommunication.Nowadays,the programmable logic controller used in the industry has beenequivalent to or close to the host of a compact computer.Its advantages in scalability andreliability make it widely used in various industrial control fields.No matter in the computerdirect control system or the centralized distributed control system DCS or the field bus controlsystem FCS,there are always a large number of PLC controllers.Keywords:programmable logic controller;industrial control;automatic control
