To realize the modular development of manufacturing system, this paper proposes a new structure of
reconfigurable manufacturing modular structure by introducing OPC technology. According to the theory hierarchical control system, we add a new OPC standard interface layer to system structure. Then, detailed design of OPC standard interface layer is presented, including design principle, the algorithm to coding OPC server/client and prototype system. Finally, the new modular system is applied in a product line of Molded-low-voltage circuit breaker. The result shows that the new module runs stably to meet reconfiguration of manufacturing system rapidly.
