t TimeStamp MX Time deadbanded magnitude last
exceeded its db configuration parameter
units Unit_Multiplier CF Unit of the attribute representing the data
db INT32U CF Measurement deadband
rangeC RangeConfig_Deadband CF Measurement range configuration
attributes
d VISIBLE_STRING255 D Description of the status element
