The system keeps a log of operational events as well as of the status of the
Industrial PC (temperature, voltage, etc.) in memory. The logs are saved in the
RAS Board memory even if the Industrial PC cannot start due to a failure, so the
user can analyze the log based on the information stored in the RAS memory in
order to identify the cause of the failure. The RAS Utility includes Filter and Find
functions to analyze logs. These functions allow the user to analyze the logs more
effectively by specifying events in a particular period or classifying events in
categories.
The RAS Utility allows the user to import/export log files. The user may export log
files to save logs to a file on a regular basis. The user may also import log files to
compare and analyze past logs with logs currently in the memory or to conduct log
analysis on another OMRON Industrial PC.
An OMRON Industrial PC's RAS system functions are achieved with the RAS
Board, RAS Middleware (RAS Service), and RAS Utility.
RAS Board: This is expansion hardware used to monitor failures that occur in the
software/hardware of an OMRON Industrial PC. The RAS Board can restart the
system to recover normal operation when it detects a failure. Additionally, it saves
power supply ON/OFF status, OS startup/shutdown status, and logs of various
failures in the memory backed-up by a battery. This enables the user to analyze
the conditions when failures occur and identify trends.
RAS Middleware: This software operates as part of Windows services. It
communicates with the RAS Board to allow the detection of failures in the
operating system. It also serves as an interface between the RAS Utility and RAS
Board.
RAS Utility: This is a resident application that is automatically activated when
Windows starts. When the RAS Utility detects a failure in the RAS Board, it
provides notification of the failure through a pop-up message that immediately
identifies the failure situation. The RAS Utility also provides functions to analyze
logs that are saved in the RAS Board memory, allowing efficient analysis of the
conditions when failures occur and trends. Additionally, the RAS Utility allows the
OMRON Industrial PC's RAS functions to be set flexibly, including the RAS Board
settings.
