Abstract

Abstract: Serial communication between computer and PLC is often used in modern industrial control. Computer is the host, PLC is the slavery, specific to the communication protocol between Mitsubishi FX PLC and the host computer, the paper gives programming and process of serial communication between PLC and host computer by VB6.0. The result of test indicates that this serial communication is accuracy for transferring data, simple and strong portability.

Key words: PLC, VB6.0, serial communication, communication protocol
