If this bit is 0, the attribute is outside the insurance range of the device when the exceeds the threshold. attribute 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. 5 - 52 C141-E034-02EN

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.
