Channel LEDs
Channel LEDs indicate the operating status of each OSA Remote I/O channel.
Channel LEDs are color-coded according to the configured operating mode of
each channel. In most cases, solid colored LEDs indicate normal operation while
flashing LEDs indicate an error condition. See Table 6-5.
Storing Log Data in a
Database
Bedrock Secure OSA Remotes provide a logging feature for recording significant
OSA Remote events and storing that information in a SQL database. A
Windows service named BedrockLogMonitor runs on the Bedrock Control
System workstation and periodically sends requests for log data to an OSA
Remote. The OSA Remote can then respond with messages that include its log
data. Log messages include information for events such as startup or shutdown,
changes in configuration, errors, and warnings. The BedrockLogMonitor service
uses an ODBC driver to write log entries to the database.
