ENERGY STORAGE METHOD AND SYSTEM TO POWER FUNCTIONAL SAFETY DIAGNOSTIC SUBSYSTEM

摘要

Disclosed is an industrial automation control system, method and apparatus and method of operation including a diagnostic domain subsystem powered by an energy storage subsystem. According to an exemplary embodiment, a diagnostic domain subsystem is configured to perform diagnostics of one or more conditions associated with a functional domain subsystem, where the energy storage subsystem powers the diagnostic subsystem during a normal mode of operation and the energy storage subsystem powers the diagnostic domain and functional domain during a power failure mode and/or power cycling mode.

1. An industrial automation control system comprising:
a power supply subsystem including one or more output voltage rails; a functional domain subsystem including processor circuitry, volatile memory and non-volatile memory configured to monitor and/or control one or more remote devices operatively associated with the industrial automation control system, and the functional domain subsystem operatively powered by one of the one or more output voltage rails during a normal mode of operation; a diagnostic domain subsystem configured to perform diagnostics of one or more conditions associated with the functional domain subsystem; and an energy storage subsystem operatively connected to one of the one or more output voltage rails and configured to store energy supplied from the one of the one or more voltage rails during the normal mode of operation and operatively power the diagnostic subsystem using the stored energy during the normal mode of operation, and the energy storage subsystem configured to operatively power the diagnostic subsystem and functional domain subsystem during a control system operation associated with a failure of one or more of the output voltage rails due to one or more of powering down the industrial automation control system, and a fault associated with an output voltage rail associated with the power supply subsystem.
