With the further research of Networked Control System (NCS), research on simulation platform of NCS has been attracting significant attention. NCS is a hybrid system aggregating time and event, which brings some difficulties in the research of NCS simulation. In this paper, a novel NCS simulation called MS2 with Simulink and Stateflow tools is proposed. MS2 simulation method is designed, and its validity is also analyzed which proves that MS2 method is effective from the perspective of hybrid system. The proposed NCS simulation method is an open simulation platform, which breaks the restriction of simulation environment based on "Black box", and provides a novel idea for simulation research of NCS.
