Abstract:
 In order to develop the soft PLC with open structure,the whole system based on the open CNC
system is divided into two modules: the development system and the operating system. With the disadvantages of
soft PLC of translation compile principle that reduce the openness and flexibility of CNC system,the proposed
method broke the tradition,which uses the interpretative type compile theory,adapting progressive scan and
keyword matching to develop soft PLC system. This study forces on the interpreted the operating system with the
function of loop execution and progressive pickup,thereby,the corresponding solution is presented. Taking the
non-real time of windows system into consideration,a platform of software based on Windows + RTX( Real-Time
eXtension) is designed to meet the real-time of the operating system. Finally,the result of the experiment shows
that the proposed interpreted soft PLC system is reliable and effective. Furthermore,it can achieve the function to
control logic instruction function of open architecture CNC system.
