Access 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
Important: 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 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 138 ).
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 valid only when synchronous
sampling mode is selected for the
corresponding channel.
8 Get Speed Data Units ENGUNIT The units context of the Speed
Value attribute. See DeviceNet Specification Volume 1
Appendix K.
This is set to Orders.
