For ensuring the trigger backup, establish a handshake with the trigger device and the process notification device.
An example of a handshake is shown on the next page.

Step 1.
The trigger device (Trigger ID: 1) turns on, and then the GOT starts the backup (Trigger ID: 1).
Step 2.
When the backup is started, the process notification device (Trigger ID: 1) turns on, and the trigger
backup processing setting No. notification (GS657) stores the trigger ID.
When the process notification device turns on, the trigger device (Trigger ID: 1) turns off.
Step 3.
When the backup (Trigger ID: 1) is completed, the GOT recognizes that the trigger device (Trigger ID: 2)
is on and the GOT starts the backup (Trigger ID: 2).
Step 4.
When the backup is started, the process notification device (Trigger ID: 2) turns on, and the trigger
backup processing setting No. notification (GS657) stores the trigger ID.
When the process notification device turns on, the trigger device (Trigger ID: 2) turns off.
