Parameter Object
(Class ID 0F
H
)
The Parameter Object provides the interface to the Standard Dynamic
Measurement Module configuration data. There are 51 Parameter Object
instances implemented in the module.
Parameter Object instances 1…4 and 7…37 are implemented to provide an
alternate method of setting the configuration parameters with EPATH or
ENGUNIT data types. Parameter Object instances 38 and 39 provide an
alternate method of setting the Produced Connection Size and Produced
Connection Path attributes for the Poll Connection because these attributes can
be difficult to get/set directly through the Connection Object. Note that these
cannot be set if there is an active Poll Connection.
Parameter Object instances 5 and 6 are for setting the starting order for the Sum
Harmonics measurements. Instances 40 and 41 are for setting the Measurement
Mode for each Channel. Instances 42… 49 are for setting the Spectrum Option
for Band object instances 1… 8. Instances 50 and 51 are for setting the Update
Rate for the Eccentricity measurements.
8 Get Value Data Type USINT Determines the data type of the
Value. 1 = REAL
122 Get/Set Calibration Bias REAL Offset added into the raw
measurement value. Used to set the ‘zero point’ for the Thrust
Position measurements.
147 Get Data Units ENGUNIT The units context of the Value
attribute. See DeviceNet Specification Volume 1
