Abstract： Aiming at problems in control system， such as the long development cycle， poor openness， complex operation， low utilization ratio and the like, the idea about reconfigurable technology was applied to develop the electromechanical control system，  a kind of modularized and static reconfigurable structure of control system was presented. On this basis， a group for action rule warehouse was defined， the analytic method of master computer and coupling mechanism of the slave computer were specified At last， based on the programming port communication protocols for Mitsubishi FX serials， its feasibility and effectiveness were validated with the visual programming software and programmable logical controller The result shows that this designing idea of system structure can make the rapid reconfiguration of the system′s outputting logic， decrease the operation complexity， improve the development effectiveness and utilization of the electromechanical equipment， and enhance the system′s flexibility
