1. When a command is sent from the host computer to the ID Controller, R/W
Head 1 enters the waiting condition and waits for the arrival of the DC. The
command data at this time specifies the memory area from which data is to
be read by R/W Head 1.
2. When the DC arrives within communications range of R/W Head 1, the data
(format and machining/inspection command data) in the memory area indi-
cated by the read command is sent to the host computer as the response.
3. Based on the response data, the host computer transmits the workpiece
machining/inspection command to the PC.
4. Once operations in the machining/inspection process have been com-
pleted, machining/inspection results data is sent from the PC to the IBM
PC/AT or compatible.
5. The host computer sends a write command to the ID Controller, and this
time R/W Head 2 waits for arrival of the DC. This command sets the memory
area to which R/W Head 2 is to write data and set the machining/inspection
results data.
6. When the DC arrives in the R/W Head 2 communications range, the machin-
ing/inspection results data is written to the memory area specified by the
DC.
