The present invention provides an interface module for transmitting data between MES and PLC. The interface module for transmitting data between MES and PLC according to the present invention is installed between an MES server for manufacture and a PLC for manufacture, can store data information while broadcasting it real-time simultaneously, can transmit data information to the MES server and the PLC without any loss of data information even in the situation of communication errors or communication failure between the MES and the PLC, can minimize the usage of a control device and store device of the PLC for processing data information transmitted from the MES server, and can maximize the equipment control capacity of the PLC. The interface module for transmitting data between MES and PLC according to the present invention includes a communication unit communicating with an MES server for manufacture and a PLC for manufacture; a memory unit capable of storing data information transmitted from the MES server and the PLC; and a control unit controlling the communication unit and the memory unit and transmitting data information to the MES server and the PLC; and allows data information generated in the MES server and the PLC to transmit through the memory unit between the MES server and the PLC, preventing data information loss due to communication errors by transmitting data information each generated at the MES server and the PLC and transmitting data information between the MES server and PLC.
