Channel Object
(Class ID 31F
H
)
The Channel Object models "front-end" processing performed on an input
signal before specific measurements are performed. This processing typically
includes gain, filtering, and/or integration.
Class Attributes
The Channel Object provides no class attributes.
Instances
There are 4 instances of this object. Instance 1 and 2 correspond to the
standard Channels 1 and 2, respectively. Instance 3 and 4 correspond to the
gSE variety of Channels 1 and 2, respectively.

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 3
and 4.
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
For instances 3 and 4, this value
is fixed at gSE = 0A00.
This setting is directly related to
the Sensitivity Units of the
associated transducer and the
Level of Integration performed
on the channel.
4 Get Integration
Level of
Integration
USINT The level of integration to
perform on the signal. 0 = None
1 = Single
2 = Double
For instances 3 and 4, this value
is fixed at 0 = None.
