LOGGERNET-SDK LoggerNet Software Development Kit


Current Version: 4.5

LoggerNet-SDK is a flexible and powerful programming tool that creates innovative client applications (such as Setup, Connect, Status Monitor) for communicating with our data loggers. It includes a reduced LoggerNet server that only allows direct RS-232 and IP communication links. LoggerNet-SDK can also be used to customize client applications that extend an existing LoggerNet installation with all of its possible communication links.

Detailed Description

LoggerNet-SDK includes ActiveX controls that encapsulate some of the fundamental tasks users want to perform with our data loggers. It also provides a limited LoggerNet Server that allows direct RS-232 and IP port connections with a single data logger.

ActiveX Controls/Functions Supported

  • Browse the data logger network to display station and data table information
  • Establish connection to a data logger via the LoggerNet server
  • Check/set the data logger clock
  • Transfer data logger programs to and from the data logger
  • Toggle ports and flags
  • Collect data from a data logger
  • Set input location variables
  • Retrieve data from the LoggerNet server cache
  • Pass CoraScript commands to the LoggerNet server
  • Access the transaction and communications log of the LoggerNet server
  • Start and stop the included, limited LoggerNet server communications DLL

Documentation and Examples Included

  • SDK Beginner’s Guide
  • Programmer’s Reference Manual
  • CoraScript Commands Reference
  • Visual C++ MFC, VB.NET, and C# .NET examples for each ActiveX control with both source code and compiled executables


  • Developer should be familiar with Campbell Scientific’s hardware and software.
  • The developer must create all of the clients that will start, stop, and administer the included LoggerNet Server DLL.

Expand AllCollapse All

  1. Check the connection between the SDK app and the LoggerNet server. This, of course, assumes that the LoggerNet server is remote and accessible to the SDK app via TCP/IP. Is the physical TCP/IP connection constant? Is there intermittent service?

    The other possibility is that the LoggerNet server is being stopped from time to time. When the LoggerNet server stops, the SDK app gets this error code.

  2. Yes, as part of the SDK—the CSIDataSource control.

  3. This can only be done by sending a different program using the FileControl() or File_Send() instruction. Data tables in a data logger cannot be added or deleted at data logger runtime using any of our data logger communication software, such as LoggerNet, PC400, PC200W, or any of the SDKs. Changes (additions, deletions, or modifications) to data tables within a data logger have to be changed inside the actual data logger program using a program editor such as CRBasic. After the data tables are modified within the program, the program must be resent to the data logger. Compiling the new program on the data logger will reset and create new tables as defined by the program.

    To clear a data table (zero out the data), the CoraScript control, found in either the LoggerNet-SDK or the LoggerNet Server SDK, would need to be used. This functionality does not exist in the BMP5 Direct SDK.

  4. This is not supported in the BMP5 Direct SDK. The options available are to specify a starting record number, get the most recent record, or collect all available records. When specifying a starting record, all data from that record forward is then retrieved. The burden is on the programmer that uses the SDK to keep track of the last record number retrieved within the program and then to retrieve what is needed or desired in the future.

    The functionality to specify a date/time data collection range is available in the LoggerNet-SDK and the LoggerNet Server SDK. Both the LoggerNet-SDK and the LoggerNet Server SDK are available for purchase from Campbell Scientific.

  5. The blog article "How to Navigate the World of Software Upgrades, Patches, and Trials" explains the difference between patches (free of charge) and upgrades (for a fee). This example quickly shows the difference between an upgrade and a patch:

    Upgrade Patch

    Major version change, such as 1.3 to 2.0

    Minor version change, such as 1.3 to 1.4

    Typically requires purchase for a fee

    Free of charge

  6. Campbell Scientific data loggers cannot communicate directly with LabVIEW. However, after retrieving data collected by any of the Campbell Scientific data loggers and placing the data in the LoggerNet data cache, the data can be shared with LabVIEW using a LoggerNet client called PC-OPC. A trial version of PC-OPC is available in the Downloads section of the PC-OPC product page.  

    The PC-OPC Server software provides a standard interface that allows third-party OPC-compatible graphics packages, including LabVIEW, to display the data logger data.

    In addition to using the PC-OPC Server and the data socket feature in LabVIEW, communication can also be established using LoggerNet-SDK with ActiveX controls.
