1. Why might the numeric and graph displays (accessed from the LoggerNet Connect screen) no longer update?

   If communication is interrupted or intermittent, LoggerNet may stop updating the Table Monitor, Numeric Display, and Graphs. When this occurs, a button on the display that is normally titled Stop (to stop the update) changes to Start, and the button must be pressed to resume the update. Also, check the update interval on the display, as it may be set to a higher value than expected.

2. Is there a possibility to auto-update the graphs in View Pro or other functions inside LoggerNet 4 without pushing the Refresh button in View Pro?

   View Pro is meant to be a file viewer, so there is no automatic update capability.

   To view graphs in real time, there are graphs that can be launched from the numeric monitor. For fully customizable displays, RTMC can be used. RTMC uses the LoggerNet server for its data source, but RTMC Pro (purchased separately from LoggerNet 4) can also use a DAT file.

3. Why does LoggerNet create a backup data file every time data collection is triggered?

   Before it appends to a TOA5, TOB1, or TOACI1 data file, LoggerNet first scans the header of that file and compares the information that it contains with the information reported in the data logger table definitions. For TOA5, the following conditions can result in errors that will cause LoggerNet to refuse to append to the file:

   • The table names do not match.
   • The number of columns does not match.
   • One or more column names do not match.
   • The number of units strings does not match the number of column names.
   • The number of process strings does not match the number of column names.

   There have been cases where, using the FieldNames() instruction, the data logger program specified a double quote character (") in the units string, and this character unbalanced the quote marks in the TOA5 format, which in turn threw off the TOA5 parser.

4. What is the station name?

   There are two station names associated with a data logger. One name is the Station Name used in the LoggerNet network map. The other name is the Station Name field in the data logger Status table. Almost all data file formats work in LoggerNet include a station name in the header of the data file. By default, the network map station name is used. However, a checkbox in the LoggerNet Setup window, Data Files tab, allows choosing the data logger Status table station name instead.

5. Does the LoggerNet server have a specific limit on the length of a generic modem script?

   The LoggerNet server imposes no specific limits on the lengths of the generic modem scripts.

6. What might cause Windows to display a "Blue Screen of Death" when LoggerNet is running?

   Typically, blue screens are the result of bad device drivers. The Internet can be very helpful in tracking down the cause of blue screens. Copy down the codes displayed. Search the Internet for “blue screen” and the code to see what device is causing the crash. Often, an updated device driver will resolve the issue.

7. How can a data logger be switched out (for example, from a CR800 to a CR1000) in LoggerNet?

   Follow these steps:

   1. In the Setup screen, record the pertinent data from the Schedule and Data Files tabs. 
   2. Delete the listed data logger.
   3. Add the new data logger. 
   4. Adjust the settings on the Schedule and Data Files tabs to match what was being done previously.
      • If the settings are complicated, review the Help menu from the Setup screen to learn more about the option in LoggerNet 4.2 to Copy Device Settings in the Tools menu.
8. Can backups from older versions of LoggerNet work on newer versions?

   Typically, a backup from an older version of LoggerNet will work on a newer version, but there will be issues trying to go from a newer version back to an older version.

9. How long does it take to install LoggerNet?

   The LoggerNet application is distributed on CD media and can be installed in minutes.

10. Does LoggerNet stay connected to the data logger after the scheduled collection is finished?

    If only scheduled collection is running, LoggerNet will connect to the data logger, collect the data, and then disconnect automatically.
