Mode
A mode is a node in the hierarchy that represents a distinct mode of operation for some equipment or system. Typically, there is only one mode for an analytic instance, indicating when the equipment is in a steady state of operation. The mode has established criteria that tell the runtime engine to process the models and evaluate rules only if the mode criteria have been met. For the purpose of writing rules, the mode is contained by the analytic instance and is the container of models.
Reference Data
In a model, reference data is the set of measured actual values that represent the normal range of equipment operating conditions in which equipment is operating in a desired manner. Filtering has been applied to this data set and is the basis for the state matrix.
State Matrix
In a model, the state matrix is a matrix of vectors in which each vector represents one of the normal operating states (for healthy behavior) of the equipment or system. Historical data from all tags in the model are included in the matrix. Using the state matrix, the runtime engine can, in real-time, compare each observation of live data to the set of normal operating states represented in the state matrix. With this comparison, the runtime engine generates an estimate for each tag in the observation and then compares the actual value to the estimate value.
Training
Training is the process used during the initial build of a model to filter out bad data and bad tags and select healthy equipment behavior to be available for the state matrix.
