An interface card connects a LAN with a drive. The interface card comprises a dual port memory interface, which interfaces to the main control card of the drive. An interrupt line informs a communication processor on the main control card to update feedbacks in the dual port memory and read the set points from the dual port memory. Special control registers interface the communication processor with the LAN. The apparatus also facilitates a method for interfacing the drive to the LAN without modifying the main control card of the drive.
