Abstract: This paper introduces the constitutes and control principle of automatic sorting system and describes the design and implementation of serial communication between the Panasonic’s FP1 series PLC and the host-computer in the system with introduction to the communication protocols and parameters setting and part of the serial-communication programs based on visual basic 6.0. The implementation of communication ensures that the automatic sorting system has the property of high intelligence, high reliability and ease of second development.
