Parameter Object
(Class ID 0F
H
)
The Parameter Object provides the interface to the Eccentricity configuration
data. There are 18 Parameter Object instances implemented in the Eccentricity
module.
Instances 1-4 and 7-16 are implemented to provide an alternate method of
setting the configuration parameters with ENGUNIT or EPATH data type.
And Parameter Object instances 17 and 18 provide an alternate method for
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.
Parameter Object instances 5 and 6 are for setting the update rate of the
eccentricity measurements. The eccentricity update rate is used in place of the
tachometer when no tachometer is available.
Instances
There are 18 instances of this object.
