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 that are 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. These
attributes 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.
