Status flag
Bit 0: If this bit is 1, the attribute is within the insurance range of the device when the attribute exceeds the threshold.
If this bit is 0, the attribute is outside the insurance range of the device when the attribute exceeds the threshold.
Bits 1 to 15: Reserved bits
Current attribute value
The current attribute value is the normalized raw attribute data. The value varies between 01h and 64h. The closer the value gets to 01h, the higher the possibility of a failure. The device compares the attribute values with thresholds. When the attribute values are larger than the thresholds, the device is operating normally.
∙Attribute value for the worst case so far
∙
∙
∙
This is the worst attribute value among the attribute values collected to date. This value indicates the state nearest to a failure so far.
Raw attribute value
Raw attributes data is retained.
Failure prediction capability flag
Bit 0: The attribute value data is saved to a medium before the device enters power saving mode.
Bit 1: The device automatically saves the attribute value data to a medium after the previously set operation.
Bits 2 to 15: Reserved bits
Check sum
Two’s complement of the lower byte, obtained by adding
