RAS Function

RAS: System Diagnostic, Surveillance Function

Industrial Computers have the following system diagnostic and surveillance function called RAS. This function enables you to monitor the operating condition of the different parts of the product and identifies faults, if any.

RAS window

  • ● Main Unit Temperature Error
  • ● Monitoring Lithium Battery Voltage And Input Voltage
  • ● Monitoring Fan Operation
  • ● Monitoring Hard Disks
  • ● Monitoring Program Crash (Watchdog Timer Monitoring)
  • ● Internal Temperature Trend Monitoring
  • ● Event Logging
  • ● Monitoring Parts Of Limited Service Life For Length Of Use

Diagnostic

Advantages

It is easy for you, the user, to identify faults, if any. This offers you the advantage of a speedy recovery from a failure, reducing recovery expenses, and management of periodic replacement of parts with limited service life.

 

Capabilities

The RAS function covers system status detection and system control as described below.

 

System Status Detection

Watchdog Timer*1 Hardware WDT to detect and notify software crash
Source Voltage Drop Detection *2 Detects source voltage drop during operation
Internal Temperature Rise Detection Detects internal temperature rise above permissible level and notifies as temperature error
CPU Temperature Rise Detection Detects CPU temperature rise above permissible level and notifies as temperature error
Fan Stop Detection Detects stoppage of intake or exhaust fans and notifies as fan stop
Hard Disk Monitor Detects and notifies hard disk errors (This applies to RAID only.)
Digital Input/Output (DI/DO, 4 Each) External digital signals (4 digital inputs, 4 digital outputs)(Interrupt signal can be specified for inputs.)

*1 DO output upon timeout on the watchdog timer is selectable with the DIP switches on the main board
*2 DO output at secondary source voltage drop is selectable with the DIP switches on the main board

 

System Control Function

Software Power Off (Shutdown) Power is turned off with power switch after automatic OS shutdown.
Remote Initialize *3 External signal restarts OS after its automatic shutdown
Remote Power On/Off *3 External signal turns power on and turns it off after OS automatic shutdown.
RAS Memory Information Storage Information on start, run, stop is stored in RAS memory (non-volatile memory with battery backup)

*3 Either remote initialize or remote power on/off can be selected. Default (before shipment): Remote initialize
