3 Get/Set Output Data
Units ENGUNIT The data units of the
signal resulting from the
signal processing
performed in the channel. See DeviceNet Specification
Volume 1 Appendix K. Also see
Parameter Object Instances 7 to
12.
Valid values:
g =1504 hex
in/sec = 2B07 hex
mils = 0800 hex
psi = 1300 hex
volt = 2D00 hex
mm/s = 0900 hex
µm = 2204 hex
Pa = 1309 hex
This setting is directly related to
the Sensitivity Units of the
associated transducer and the
Level of Integration performed
in the channel.
4 Get Integration
Level of
Integration
USINT The level of integration to
perform on the signal. 0 = None
1 = Single
5 Get/Set Low Cutoff
Frequency USINT The effective high pass
filter (low frequency
corner) selection. 0 = Very low
1 = Low
9 Get/Set Name STRING2 A name to help identify
this channel.
10 Get/Set Full Scale REAL The maximum signal
expected to be processed
by the channel. Output Data Units + Overall
Base Measurement Class (RMS,
Pk, Pk-Pk)
Setting the Full Scale to a
greater value allows the
channel to handle greater input
signals without saturating or
clipping. Setting the Full Scale
to a lesser value allows the
signal to be measured with
greater resolution.
100 Get Very Low HPF
Corner
Frequency REAL The frequency, in Hz, of
the "Very low" Low
Cutoff Frequency option
for attribute 5. Hz
101 Get Low HPF Corner
Frequency REAL The frequency, in Hz, of
the "Low" Low Cutoff
Frequency option for
attribute 5. Hz
