3 Get Magnitude
Value REAL The measured magnitude
value.
4 Get Phase Value REAL The measured phase
value. Degrees
5 Get Status BOOL Indicates if a fault or
alarm has occurred. 0 = Operating without alarms of
faults.
1 = Alarm or fault condition
exists. The Value attributes
may not represent the actual
field value.
6 Get Magnitude Data
Units ENGUNIT The units context of the
Magnitude Value
attribute. This setting is determined by the
Channel Object’s Output Data
Units setting (see page 125).
7 Get/Set Speed Value REAL The speed at which the
magnitude and phase are
measured. A multiple of the measured
machine speed
