The implementation of communication between the upper computer and lower PLC of rescue robot

Abstract

The realization of communication between PC and PLC is the basic constituent part in rescue robot control system. It has direct impact to the function of entire system. This paper introduces a method in detail which can make the communication between the rescue robot upper computer and lower PLC come true. It also analyses how to implement communication between S7-200 programmable logic controller and personal computer in the mode of free port, and given the programming instance. Practice indicates the idea of the scheme is succinct and also very effective.
