4.7 VIEWING LOGGED INFORMATION
4.7.1 Introduction
The Microlok II system logs and reports information in three classifications. These are critical
errors, warnings, and operational events. The Historical Data section of the Maintenance Tools
main menu contains four tools that enable you to review the logged system information in several
ways:
• The user data log records only those events that the user specifies.
• The system event log records up to 5000 of the most recent critical errors, warnings, and
events.
• The system error log records up to 50 of the most recent critical system errors.
• The merged events log enables you view errors, warnings, and events as in the system event
log. This log also provides graphic displays of parameters and events as specified in the user
data log.
4.7.2 Viewing the User Data Log
The user data log enables users to monitor a specifically chosen set of events. These events are
assigned in the configuration section of the Tools program (see section 4.12.4). The system then
records in the log any state changes of the assigned events, along with the date and time that each
state changes occurs. This log is capable of recording up to 90,000 of the most recent specified
boolean changes, or at least 64,000 boolean and/or numeric changes. To view the user data log,
click on the User Data Log button on the Maintenance Tools main menu.
The first screen allows the user to determine how much of the log to view. This window is
shown below:
These options are available from the first screen:
