Abstract
A machinery health monitoring module processes machine vibration data based on vibration signals and provides the machine vibration data to a distributed control system. A distributed control system operator computer executes a software user interface that filters relevant configuration parameters based on a selected machine measurement type so that only those parameters that are applicable to the selected measurement type appear on the user interface screen. Further, configuration parameters for individual measurement values within the measurement type are made available only when a particular measurement value is selected for acquisition. This greatly simplifies the information that is displayed on the configuration user interface.
