RAS Functions
•
Alive Monitoring: Provides notification of failures that occur while the OS is
running (i.e., from startup to shutdown).
•
Shutdown Monitoring: Provides notification of failures that occur while shutting
down or rebooting.
•
External Power Supply Undervoltage/Interruption Monitoring: Detects
abnormal power interruptions for the external power supply.
•
Temperature Monitoring: Detects abnormal temperatures in the Motherboard.
•
Voltage Monitoring: Detects abnormal power supply voltages in the
Motherboard.
•
Cumulative Operating Time Monitoring: Detects excessive cumulative
operating time.
•
RAS Board Monitoring: Detects errors in the RAS Board.
•
LCD Monitoring: Detects errors in the LCD.
Action on Error (Forced Shutdown/Forced Reboot)
This function can enable systems to recover to improve the operation rate or
terminate the system to prevent further faults after detecting a failure.
OMRON Industrial PCs with RAS functions have the following capabilities:
•
Rebooting the system automatically when the operating system freezes,
•
Starting the system and restoring operation automatically after the Motherboard
stops because of a failure, such as overheating due to runaway operation,
•
Repeating reboot attempts automatically until the system is successfully
activated, if the system hangs up at startup, and
•
Forcefully terminating the system automatically when the system takes too much
time to shut down.
Failure Notification
The Failure Notification function reports a failure when the failure occurs or after
the system recovers from the error. It notifies the user of a failure with a pop-up
message that allows the user to immediately identify the situation without fail.
•
The user is notified of power failure that causes shutdown of the system.
•
When the system goes down due to some failure, this function notifies the user
of the nature of the failure and the status of the Industrial PC after the system
recovers from the error.
•
The user is immediately notified of any abnormal temperature or voltage in the
Motherboard.
•
The user is notified that LCD Backlight lifetime is nearing its limit.
Status Monitor
The industrial PC’s operating status can be monitored from the RAS Utility. The
following RAS information can be monitored:
•
Motherboard temperatures (CPU temperature and chipset temperature),
•
Motherboard voltages (2.5 V, Vccp, VTR, 5 V, 12 V, HVCC, 1.5 V, and 1.8 V
values),
•
Cumulative operating times (motherboard/LCD and RAS Board),
•
RAS system settings,
•
LCD operating status,
•
RAS Board operating status,
•
Number of errors that have occurred, and
•
Failure status.
