Abstract
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.
