9. BACKUP FUNCTION
9. BACKUP FUNCTION
(ONLY WHEN THE BACKUP MASTER IS CONNECTED)
(1) Function
• By connecting the backup master terminal (BM), the various files stored in the master terminal (M) can
be backed up.
• The terminal assigned to ID No. 2 will function as a backup master terminal (BM). By programming ID
No. 2 in the terminal connection table and downloading this data to each terminal, the system will
function as a system in which the backup master terminal (BM) is connected.
• By changing terminal ID from 2 to 1, the backup master terminal (BM) will function as the master
terminal (M).
<Files to be Backed Up>
NOTES: 1. Data capture (DC) transaction files are not backed up.
2. The tables (center files) managed by the master terminal (M) and used by each terminal via
inquiries and PC transmission information tables are backed up.
• Sales data is backed up on a real-time basis.
When sales data of the master terminal (M) is updated, sales data of the backup master terminal (BM)
is updated at the same time.
• Backup data check function:
Correspondence between the center files and backup data is checked every certain period of time.
• 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.
