    You may need to verify if your firewall will allow NTP or Rdate packets to pass through. Generally, it is better to use a local time server if possible. The time server time.leviton.com supports both NTP and Rdate time protocols. If you use a GSM connected system, you will probably need to use Rdate.
  • Page 33 11 SYSTEM OPTIONS If you store data in local time, you will have the following issues. Local time is relative. Is Local the time where the DAS exists, or local to where the data is stored? If local to the DAS , you must shift each DAS data set depending on its location. There are about 11 time zones in the US.

The Reset Configuration option will remove all the user settings, data, and passwords that have been configured and will return the DAS to the factory default settings.

  • Page 38: Log File Data

    14 LOG FILE DATA The DAS stores data from the modbus devices in text (.CSV) log files. One log file is created for each modbus device on the system. On a daily basis, the log files are “rotated”, that is, the current log file is renamed and compressed with gzip compression, and a new log file is started.
  • Page 39 14 LOG FILE DATA Comments: Date/Time: The date/time column reports the time at which data was logged from the Modbus device. Note: this is not necessarily the time at the start of the log cycle. Users with large number of devices may notice some of the Modbus devices at higher address numbers report 1 or 2 seconds after the first Modbus devices.
