Exception Detail Warning
Attribute ID #14 identifies the specific warning condition(s) detected by the DMA transducer.
This attribute is a Structure of three Structures containing a bit ma
pped representation of the
warning detail. This structure contains a total of 9 bytes. The first group contains 3 bytes
representing Common Exception Detail Warning Bytes. The second group contains 4 bytes
representing Device Exception Detail Warning Bytes. The third group contains 2 bytes
representing Manufacturer Exception Detail Warning Bytes.
The response is a byte with each bit representing a specific exception (alarm) condition, as listed
in Table 46. The bit that is set indicates that the alarm
assigned to that bit is active. The response
returns a binary (hex) value with the least signi
ficant bit (bit 0) as the last digit. The response
values are additive; therefore, one hex value reports all alarm conditions.
