US Patent 7975184 Diagnostic access system

A dedicated processing system for monitoring, processing and combining mass statistical diagnostic data of a process control system. Through real time and near real time network health monitoring by the system statistical inferences can be made to anticipate potential system and device problems with notification(s) to users. A variety of user alerts are facilitated, including status and warning LEDs, direct display, and display on a networked computer. Multiple systems can be employed and systems will discover each other and interoperate. Specific systems can be specified to gather and unify diagnostic data from installations with multiple systems.
