1. How can data from LoggerNet be added into the SCADA software OSIsoft PI?

   OSIsoft sells a PI interface for LoggerNet. The OSIsoft part number is PI-IN-CS-LN-NTI. Please direct all inquiries for sales and support of the interface to OSIsoft.

2. Is there any way to set a variable in the data logger using LoggerNet to gain manual control over when data is collected by the data logger?

   A program snippet, such as the one below, would work for this purpose. The Boolean variable can be toggled from the Ports & Flags screen in LoggerNet (accessed via the Connect screen), through the Numeric Display (also accessed via the Connect screen), or under program control.

   public StoreDataFlag as boolean

   DataTable (ConditionalTable,StoreDataFlag,100)

             Sample (1,counter,Long)

   EndTable

   When storing data conditionally, be sure to allocate a specific number of records in the size parameter of the DataTable() instruction. For more information, see the Data Table Memory Allocation Tutorial.

3. How can LoggerNet be used to edit the user drive size in the data logger settings?

   Follow these steps:

   1. Connect to the data logger using the LoggerNet Connect screen.
   2. Find the data logger in the Stations list, and right-click it.
   3. From the menu that is displayed, choose the Settings Editor.
4. How can data during a certain duration be erased without erasing the configuration and the program?

   There is no mechanism to selectively erase data from the data logger for a given date range. However, the data tables in the data logger can be reset, which effectively erases the data.

   Note: Following these steps will cause the loss of all data:

   1. In the LoggerNet Connect screen, click the Station Status button.
   2. When the dialog box opens, select the Table Fill Times tab, which shows the data tables in the data logger and their sizes.
   3. Either select individual tables, or select the Select All checkbox.
   4. Click the Reset Tables button. This will erase all data in the tables.
5. Can two different communications paths to one data logger be set up in LoggerNet?

   LoggerNet can be configured to have two paths to a data logger, simply by entering the data logger twice in the network map with different comms links. LoggerNet, however, treats them as separate entities, so it will try to collect all the data twice via the two separate paths if both are enabled. Some users have set this up where they use one route most often, and manually enable collection to the backup route if the main link is lost.

   An alternative to this scheme is to set up the backup route but not add the data logger. Then, if the main link to the data logger goes down, simply drag-and-drop the data logger to the backup route. After the main link is working again, the data logger can be moved again. This keeps data collection pointers for that data logger intact.

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. Is there a way to set LoggerNet to download only the last x number of hours of data?

   On table-based data loggers, in the LoggerNet Setup screen, on the Data Files tab, there is the Collect at Most option that can be used to indicate how many records to collect. Based on how often data is stored, a calculation can be made to determine how many records represent x hours of data.

8. Does LoggerNet anywhere indicate the battery level of the connected data logger?

   For PakBus data loggers, the battery voltage is found on the Station Status screen. (The Station Status screen is accessed from the LoggerNet Connect screen.) For mixed-array data loggers, Station Status will display the lithium battery and the number of times the 12 V supply has dropped below an acceptable level. If the battery voltage is being read by the program, it may be available from the public table.

9. Can a data logger be configured to place a call to a PC running LoggerNet?

   Yes. If the data logger has a phone modem connected, there are Edlog and CRBasic commands that can be used to initiate calls. For example, in CRBasic a call can be made with SerialOpen(), SendVariables(), and SerialClose() instructions.

10. Does the license for LoggerNet include the application in a virtualized form (App-V sequencing)?

    No. For the current licensing information, refer to the LoggerNet Instruction Manual.
