1. An apparatus for providing historical data regarding machine operating parameters, comprising:
- a plurality of sensor means for producing signals indicative of the level of machine parameters, said machine parameters including a first operating parameter and two or more dependency parameters, at least one of said dependency parameters being different from said first operating parameter;
means for selecting a processing method according to which operating parameter data is to be processed;
control means for receiving said signals and selecting data representative of said first operating parameter in response to a dependency definition being satisfied and discarding data representative of said first operating parameter in response to said dependency definition being unsatisfied, said dependency definition including a plurality of predefined ranges, each of said dependency parameters corresponding to one of said predefined ranges, said dependency definition being satisfied in response to said two or more dependency parameters each being within the corresponding predefined range;
memory means for storing the level or levels associated with the predefined range for each of said dependency parameters, each of said predefined ranges being accessible by said control means; and
compiling means for receiving the selected data from said control means, processing said selected data according to the selected processing method, and storing the processed data in said memory means.

Abstract
When compiling machine performance data it is advantageous for such data to have been acquired during periods in which the machine was in the same general operating state. The subject invention provides a system for producing historical data regarding machine operating parameters and including a plurality of sensors for producing signals indicative of the level of machine parameters. A control is included for selecting data representative of a first operating parameter in response to a dependency definition being satisfied and for processing the selected data to provide an indication of machine performance.
