PURPOSE:To eliminate the waiting time of a master equipment and to efficiently operate the master and satellite equipments by receiving a command from the master equipment to a storing means irrespective of the processing state of the respective satellite equipments. CONSTITUTION:When the command constantly transmitted from the master equipment is received in the satellite equipment, it is temporarily stored in a buffer RAM 6. At the time of receiving the command, a sequence number is attached and the contents are stored in a data area. Then, at an arbitrary time, the start of a command processing is instructed from a keyboard 1 or the like, thereby, an operation program based on a prescribed flow stored in a ROM 7 operates a CPU 4. Accordingly, according to the processing state of the satellite equipment, the received command can be constantly processed and the waiting time of a command transmission unable is not applied to the master equipment. |
