In a command processing system for processing a command sent from an external controller ( ) to an equipment ( ) via a digital interface ( ), a status/command storage unit ( ) stores the last executed commands to inform the external controller ( ) of contents thereof in response to the command. Meanwhile, a management information storage unit stores the management information just before and just after execution of the received command, wherein upon receipt of a command (Z) for inquiring contents of the previously executed commands, the commands (X, Y) stored in the status/command storage unit ( ) are read out to produce a response data to the inquiring command. Thus, the user can easily know the content of the last control command provided for controlling equipment.
