Device Status:
The eight standard status conditions (present in ANY HART field device) are all represented by a Boolean “true” or
“false” state. These eight conditions, discussed on page 7, are:
D DEVICE_MALFUNCTION
D CONFIGURATION_CHANGED
D COLD_START
D MORE_STATUS_AVAILABLE
D LOOP_CURRENT_FIXED
D LOOP_CURRENT_SATURATED
D NONPRIMARY_VALUE_OUT_OF_LIMITS
D PRIMARY_VALUE_OUT_OF_LIMITS
Detailed Device Alerts:
The Alert Groupings are:
D ADDITIONAL_STATUS_0
D ADDITIONAL_STATUS_1
D ADDITIONAL_STATUS_2
D ADDITIONAL_STATUS_3
D ADDITIONAL_STATUS_4
D ADDITIONAL_STATUS_5
D ADDITIONAL_STATUS_6
D ADDITIONAL_STATUS_7
Each of these status bytes represent eight individual bits with values that range from “00” to “255”. To determine
which of the eight bits are active requires converting a decimal value to its binary equivalent value. Refer to Command
48 on page 17 for details on the individual alert bits inside of each Additional Status Byte.
