System log
The Daniel 3410 Series Gas Ultrasonic Flow Meter meter logs all system messages in the
system log.
The meter can store up to 3000 system records. The user can select whether old, unread
records can be overwritten by new records when the log becomes full via the data point
DoOverwriteUnreadSystemLog.
This point can be modified using the Daniel MeterLink Tools > Edit/Compare
Configuration screen. The default is to overwrite old, unread records. Refer to
reading audit, alarm, and/or system log records
marking records as read. The data point IsSystemLogFull indicates whether or not the
system log is full and cannot overwrite old, unread records.
Repetitive system messages are prevented from filling up the system log. When a
particular system message occurs 3 times within 60 seconds, that system message is
suppressed until that message's frequency drops below the 3 times-per-60 sec rate. The
system log records indicate when a system message suppression is started and ended.
6.1.3 Reading log records
Daniel 3410 Series Ultrasonic Flow Meter log records are read using the Daniel MeterLink
Logs/Reports > Meter Archive Logs screen.
