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.
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.
