| Abstract: | Serial communications between PC and PLC are introduced in this paper.Inferior PLC is in charge of field data acquisition and real-time control,while superior computer displays a human-computer interface using higher-level language.When working,PC operates VB monitor interface,and manages PLC and the motor.PLC is used mainly to acquire information,to control and to accept message of the motor as well as the system.Part of the program design of PC and PLC communication is given.Finally,a simple running demonstration is made. |
