• Backup data update process:
When an error occurs in backup data, the following processing methods can be selected
according to the program option setting.
(1)Automatic data copy
When the version of the center file stored in the master terminal (M) is different from that
stored in the backup master terminal (BM), registration jobs are automatically prohibited,
the backup data is properly exchanged.
While updating the backup data, each inquiry from the terminals may result in a “MASTER
IS BUSY” error.
(2)Manual data copy
When the version of the center file stored in the master terminal (M) is different from that of
data stored in the backup master terminal (BM), the master terminal (M) gives a short beep
at the timing of issuing the long receipt to warn that the data is not backed up properly.
The operator should update the backup data manually.
(2)Procedure
1) Changing Program Data (DLL from the PC)
• When various center files from the PC are received via DLL, the master terminal (M) backs
up program data and sales data of the backup master terminal (BM) automatically and
sends the result to the PC.
2) Changing Program Data (Operated on the Master Terminal)
• When center files are being programmed on the master terminal (M), the backup error flag
of the relevant file is turned on. (At this time, backup data is not updated.)
* For details about the backup error flag, refer to 5) Backup Error Flag.
* For an explanation of the backup data update process, refer to 6) Backup Data Update
Process.
3) Updating Sales Data
• For details about updating sales data, refer to the explanation of each of the control func-
tions described in Chapter 7.
