Tasks to Monitor the System This chapter describes some of the key tasks to complete to monitor and
maintain your enhanced redundancy system.
Controller Logging Beginning with enhanced redundancy system revision 19.052, you can use the
controller logging feature. This feature provides a way to detect and log changes,
that is, RSLogix 5000 software and controller mode switch interactions, made to
ControlLogix 1756-L6 x and 1756-L7x controllers without adding any auditing
software.
With controller logging, the controller can perform these tasks:
• Detect changes and create logs entries containing information about the
changes.
• Store the log entries to a Compact FLASH (CF) card or Secure Digital
(SD) card for later review.
• Provide programmatic access to log entry counters to provide change
detection information remotely
