3 Get Overall Value REAL Measured value The output value of the measurement
performed by the Overall Measurement
Object on the input signal. The result of the
measurement process specified by
Measurement is converted to the units
specified by Data Units to produce the
Overall Value.
4 Get Status BOOL Indicates if a fault or alarm has
occurred. 0 = Operating without alarms or faults.
1 = Alarm or fault condition exists. The
Overall Value attribute may not
represent the actual field value.
5 Get Data Units ENGUNIT The units context of the Overall
Value attribute. This setting is determined by the Channel
Object’s Output Data Units attribute (see
page 138 ).
6 Get/Set Measurement USINT The measurement (or calculation)
performed to produce the Overall
Value. 0 = RMS
1 = RMS peak
2 = RMS pk-to-pk
3 = Peak
4 = Peak-to-peak
