Data Logging
Data logs are available for Alarms, OCM flow, Daily Totals, and Primary Variable. The logs can be
examined locally via LUI (see View Logs (3.2.6.), or by uploading the logs to a PC using USB and the
Web Browser tool on a computer.
Using the Web Browser tool, choose menu item Maintenance and Diagnostics > Diagnostics > Data
Logs page which displays a Load Logs button. Click this button and you will be prompted with a
dialog box that allows you to choose the location on your local PC where the uploaded logs will be
placed. Note that the logs uploaded at this point will replace any previous logs you may have
uploaded before, so be sure to choose an empty directory here to avoid losing logs you may have
uploaded in the past.
Log files written to a local computer drive via USB, are comma-delimited files, and a list of file
headings for each type of log is shown below.
To clear entries when log memory becomes full, see
Viewing the Data Log on page 119.
