Abstract:
1. A method for monitoring a control application, said method comprising: accessing a plurality of data sources for said control application; retrieving, from said data sources, data regarding events occurring in a manufacturing environment monitored by said control application; compiling said data to generate, for said events, records of dataflow paths within said control application, each of said records of said dataflow paths corresponding to a specific event, indicating a type of said specific event and further indicating at least one specific data source to which a data posting was made during said specific event; storing said records of said dataflow paths in a data storage device; and performing an analysis of said records to detect a dataflow interruption within said control application, said analysis comprising comparing a current dataflow path record to historical dataflow path records for same type events to identify differences in data postings indicative of said dataflow interruption.
