How the Atrium processor behaves after an action on the PC

General

The following table describes the different actions on the PC and what implications they have for the Atrium processor:

Action on the PC	Behavior of the Atrium processor
Accidental disconnection from the mains and reboot of the PC containing the Atrium	warm restart if the application environment has not changed (1).
Micro-outages on the network supplying the PC	As the Atrium processor does not have a filtering mechanism for micro-outages, every micro-outage not filtered by the PC’s internal power supply causes a warm restart of the processor, if the application environment has not changed (1).
Restart software control: Restart	This action has no effect on the operating status of the Atrium processor (if the processor is in RUN mode, it remains in RUN etc.). It triggers neither the warm start nor the cold start of the processor.
Shut down software control: Shut down	The Atrium processor carries out a warm restart if the application context has not changed when the PC starts up. Note: if the 24 V power supply is present and connected, this control has no effect on the operating status of the Atrium processor (the PCI connection is lost however)

(1) if the optional 24 V power supply is present and connected to the mains, the disconnection of the PC from the mains does not effect the operating of the Atrium processor.

NOTE: A PC software blockage has no effect on the current state of the processor (identical behavior to a PC software RESET).
