• The method for processing the backup error is selected according to a program option setting. Even if
the automatic data copy operation is selected, data copy can also be performed manually.
1Automatic data copy
When the backup error flag is on (or turned on) , the master terminal (M) automatically sends to
the backup master terminal (BM) the file in which the error has occurred, and updates the backup
data.
2Manual data copy
The backup data is updated by the manual operations of the operator.
* When the backup data is being updated, inquiries from terminals may result in a “MASTER IS BUSY”
error.
* When a “MASTER IS BUSY” error occurs, clear the error using the [C] key. Then, update the backup
data again after the master job (backup process) is complete.
* Only the files with the backup error flag turned on are sent to the backup master terminal (BM) to
update the backup data.
* When the master job is being done on the master terminal (M) ([RTR] key is turned on), backup data is
not checked or updated.
