Name Data Type Description Semantics
3 Get DC Bias REAL The measured average DC bias of
the transducer signal in volts. Volts
4 Get Status BOOL Indicates whether a transducer
fault exists (the measured DC Bias
is outside the range specified by
Fault High and Low). 0 = No fault
1 = A transducer fault exists
5 Get/Set Sensitivity Value REAL Value of the sensitivity of the
transducer in millivolts per
Sensitivity Units. See Valid Full Scale Selections for valid
Sensitivity and Full Scale value pairs.
6 Get/Set Sensitivity Units ENGUNIT Units of the denominator of the
Sensitivity Value. See DeviceNet Specification Volume 1
Appendix K. Also see Parameter Object
instances 1 and 2 (
page 128 ).
Valid values:
g = 1504
h
in/sec = 2B07
h
mil = 0800
h
psi = 1300
h
volt = 2D00
h
mm/s = 0900
h
μm = 2204
h
mbar = 1308
h
Pa = 1309
h
7 Get/Set Fault High REAL The maximum expected DC Bias
voltage from the transducer in
volts. Volts
A reading above this value causes a
transducer fault, which is indicated by the
Channel status indicator flashing red.
