Design of Communication Among Vision System, PLC and Industrial Robot based on Modbus-TCP protocol

摘要

Abstract In order to solve the problems of small system, single machine and single function operation of industrial robots and improve the automation of the system, Modbus-TCP protocol is used as communication platform to realize data exchange among industrial robot, vision system and main control PLC, and an automatic assembly control system composed of Siemens S7-1200 PLC, industrial robot, vision system, conveying line and assembly line is constructed. The application of the system in automatic identification and assembly line will improve production efficiency and reduce labor costs.
