9 System Backup
9.3 Automatic Backup Function
MH900, DX200 Controller
With the automatic backup function, all the part where the internal data is
stored in the physical memory area is collectively saved. If there is any
data which is in the middle of changing while executing the automatic
backup function, the data might not be usable for restoration because of
its inconsistency. Therefore, the function is terminated with an error during
the play back operation or while the manipulator is in motion so that the
automatic backup cannot be operated. Set the automatic backup function
to be executed while the manipulator is not in the playback status and
while the manipulator is stopped.
The automatic backup function has the following functions and features.
No Function/Feature Explanation
1
Cyclic backup
In the teach mode, the data in
memory is backed up in a specified
cycle from a specified starting time.
This function backs up as much of
the latest data as possible during
editing. The backup data saved in
the CompactFlash can be loaded to
the controller in case of data loss so
that the damage can be minimized.
2
Backup when switching modes
When switching the mode from the
teach mode to the play mode, the
data in memory is backed up.
The editing data is backed up when
editing is completed. The latest data
is automatically backed up with this
mode.
3
Backup when start-up
When the controller is start-up, the
data in memory is backed up.
When the controller starts up, the
data in memory is backed up. Since
the editing/playback operation is
usually completed when the
controller power is turned OFF, the
latest data is automatically backed
up with this mode.
4
Backup when inputting specified
signals
The data in memory is backed up
when a specified signal (#40560) is
input.
The data in memory is backed up
by the signal from the host at the
intended timing. Although the
above mentioned items 1 to 3 are
designed to back up the data
automatically, this function backs up
the data in accordance with the
instruction from the host.
5
Backup while robot program is
stopped
The backup during playback is
disabled. However, in the play mode,
the backup is enabled if the robot is
stopped. (“Cyclic backup” and
“Backup when inputting specified
signals”)
Backs up the variables for essential
data.
6
Backup and retry at low priority
The data in memory is backed up at
low priority so that this operation
does not affect the other operations.
When other operations affect the
backup operation, the backup is
suspended and retried later.
The backup operation hardly affects
the other operations so that the
programming pendant can be used
even during the backup operation.
7
Backup in binary
The data is saved as binary data.
Backup in binary allows the system
to be easily and speedily restored.
8
Setting of items
Parameters can limit the settings of
the backup condition.
Unnecessary settings can be
avoided with this setting.
