System for processing command sent from external controller by executing information stored just before and after the processing and informing back to controller the contents of command |
摘要 |
In a command processing system for processing a command sent from an external controller (111) to an equipment (100, 200) via a digital interface (112), a status/command storage unit (103) stores the last executed commands to inform the external controller (111) 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 (103) 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.
