ABSTRACT:
An apparatus and method including a fieldbus interface board connected to a fieldbus line. The fieldbus interface board includes a main control unit controlling an overall operation of the board. A main memory inputs and outputs data required for the operation of the main control unit, wherein the main control unit controls the main memory. A fieldbus control unit controls transmission and reception of fieldbus data. A buffer memory buffers the fieldbus data to be transmitted to the fieldbus line or to be received from the fieldbus line. A fieldbus access unit transmits the fieldbus data to the fieldbus line or receives the fieldbus data from the fieldbus line, wherein the fieldbus control unit controls the buffer memory and the fieldbus access unit.
