7.6.2.4.5 Data backup
The "Save values" command can be used as often as desired in the screwdriver operation,
but however, only the last three values are saved. In case of an error or a failure, the
values are always saved.
The value last saved is always available in the range Step_3 / Torque_3 / Angle_3.
When using the "Save values" command multiple times in the screwdriver program, the
previous values are shifted upwards (Step_3  Step_2  Step_1).
If an error occurs during the screwdriver operation, the screw fixing values of the incorrect
step are saved in the range Step_NOk / Torque_NOk / Angle_NOk.
