System diagnostics

SmartFlux System diagnostics are supported by the combined release of win-GHG interface software v8.8.36 and SmartFlux 2/3 System embedded firmware v2.2.50. This feature serves to summarize the system performance by providing status indicators for components and configurations, allowing you to evaluate the system at a glance. Diagnostics are under Diagnostics > SmartFlux tab.

Note: Diagnostics are updated every 15 seconds except when the SmartFlux System is executing an EddyPro run, as indicated by a banner:

Diagnostics refresh at the conclusion of the run (typically 7 to 15 minutes).

To support this feature, the win-GHG application attempts to open port 5050 for communication with the SmartFlux 2/3 System. If the local network prohibits opening port 5050, you will be presented an error message stating that the connection is not possible because port 5050 may be blocked. Contact your network administrator for assistance. If using win-GHG software v8.8.36 and SmartFlux v2.2.49 or earlier, the SmartFlux Diagnostics are not available.

Clock

Clock diagnostics show the time keeping status to help with troubleshooting of timing issues.

Issue Status Description
GPS Firmware Version:
  Message GPS 18x-LVC software ver. 4.3, for example. Compatible firmware versions are 3.8, 3.9, and 4.3 or newer. If the antenna reports 3.7 or older, 4.0, 4.1, or 4.2, replace the antenna with a newer model for reliable performance. Contact LI-COR or your representative for more details.
  Unknown Unable to retrieve information at this time. Typically, wait 15 to 20 more seconds for the information to refresh.
Time Source:
  Primary Precision Time Protocol is running on the SmartFlux 2/3 System in preferred mode. GPS-driven time in the SmartFlux System is the primary clock.
  Secondary Precision Time Protocol is running on the SmartFlux 2/3 System in slave mode. The SmartFlux System is not the primary clock.
Reading GPS Receiver Time?
  Yes GPS receiver is providing valid time.
  No GPS receiver time not valid. Receiver positioned poorly (inside)? Cable unplugged? Failed receiver or cable?
Synced to GPS Satellite Time?
  Yes System clock is synced with the GPS satellite time.
  No System clock is out of sync with GPS satellite time.
GPS Satellites detected:
  # of satellites detected. May be 0 when in a building. >4 is ideal.
Time sources consistent?
  Yes The win-GHG software was able to sample the clocks on both the SmartFlux 2/3 System and the LI-7550 or DSI and that they were satisfactorily synchronized.
  No The two clocks are >2 minutes off. If NO, an error icon will be displayed next to the Time Sources Consistent line and both the SmartFlux Epoch Time and GHG Epoch Time1 will be displayed underneath for diagnostic purposes. To troubleshoot time issues:
  • Make sure the GPS receiver is not in an enclosure.
  • Make sure you are using LI-COR approved network switch.
  • Make sure PTP is set to Automatic on all LI-COR devices.
  • Make sure the date and time are set correctly.
  • Reboot all system components.

Sonic Data Collection

Sonic data collection shows the status of the sonic anemometer and SmartFlux System anemometer data handling.

  Yes The SmartFlux 2/3 System was able to align the high-speed anemometer data and gas data and save the file.
  No The SmartFlux 2/3 System was unable to align the high-speed anemometer and gas data. Expect the next EddyPro run to fail.
    Click Yes/No to view the log for more details (see Sonic data collection information). Copy the log to the clipboard with Ctrl + C for consultation with a LI-COR technician.
Sonic File Names Consistent:
  Yes The SmartFlux 2/3 System has recorded anemometer data files that have consecutive time stamps.
  No Raw anemometer data files have non-consecutive time stamps. If a response of NO is not resolved after rebooting the SmartFlux System, contact LI-COR for assistance.
Digital Sonic File Storage Capacity
  Good Anemometer data files stored on the SmartFlux 2/3 System are within the allotted storage space.
  Exceeded Anemometer data stored has exceeded the storage allotment, indicating a data management issue. These files are automatically deleted normally. Contact LI-COR for assistance.
