Rule Name Data Type Description Semantics
3 Get Magnitude
Value
REAL The measured magnitude
value.
4 Get Phase Value REAL The measured phase
value.
Degrees
Note: Not valid for instances 5
and 6.
5 Get Status BOOL Indicates if a fault or
alarm has occurred.
0 = Operating without alarms of
faults.
1 = Alarm or fault condition

ENGUNIT The units context of the
Magnitude Value
attribute.
This setting is determined by the
Channel Object’s Output Data
Units setting (see page 128
).
7 Get Speed Value REAL The speed at which the
magnitude and phase are
measured.
Instances 1 and 2 use 1X
machine speed.
Instances 3 and 4 use 2X
machine speed.
Instances 5 and 6 use 3X
machine speed.
The value is only valid when
synchronous sampling mode is
selected for the corresponding
channel.
8 Get Speed Data
Units
ENGUNIT The units context of the
