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. 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.
3. 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.
4. How does LoggerNet handle data collection when the data logger stores data to a CompactFlash card?

   LoggerNet collects data from the data logger first. If there is additional data on a CompactFlash card, LoggerNet collects that also. Nothing special needs to be set up in LoggerNet to have this occur.

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. 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.

7. 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.

8. 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.

9. 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.
10. 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.
