Change the log duration

Change the log duration of a data log to change how long the data log collects the specified tag values on an HMI device. Specify the log duration in minutes, hours, or days. For example, to collect data for a day, specify one day as the log duration. The default log duration is seven days. The maximum log duration is 365 days.
To change the log duration
  1. In the
    Project Explorer
    , expand the
    Data Logs
    folder and double-click the data log. The data log opens in the
    Data Log
    tab.
    TIP:
    Right-clicking the data log in the
    Data Logs
     folder and selecting
    Open
    opens the data log.
  2. In the second box after
    Log Duration
     at the top of the data log, select the duration and unit of measure for the duration. For example, type
    14
     and select
    days
    to have the data log start collecting data for two weeks once the project downloads to the HMI device.
    TIP:
    Tips:
    • Changing the log duration causes previously collected data to no longer appear in the data log when the project downloads again.
    • If there is no change to the sample rate, log duration, or number of tags in the data log, previously collected data in the data log remains unchanged when re-downloading the project to the HMI device.
    • The
      Log Duration
       box has a red outline if it does not contain a valid entry. Enter a valid log duration between 1 of any of the selected units and 365 days. 8760 hours and 525,600 minutes are both equivalents of 365 days.
