Understand the major concepts that underpin NI-XNET and general NI-XNET programming tasks so you can successfully create programs for your interfaces.

NI-XNET State Models for Ethernet
The NI-XNET driver encompasses two state models: a model that governs the driver session and another model that governs the interface.
NI-XNET Session Modes for Ethernet
In general, the NI-XNET session mode specifies the type of data and the direction of data in the session, as well as how data is transferred between your application and the network. NI Ethernet interfaces support specific NI-XNET session modes.
Creating a Basic NI-XNET Program
At its most basic, NI-XNET allows you to read information from a network or to write information to a network. You can create complex applications with NI-XNET, but it is possible to create a basic, functional NI-XNET program with these elements alone.
Choosing How to Create NI-XNET Sessions
NI-XNET includes two methods for creating sessions: a LabVIEW project and the NI-XNET Create Session function. You typically use only one method to create all sessions for your application; each method is best suited to different situations.
Required and Optional NI-XNET Properties
When you create a new object with NI-XNET, the properties may be optional or required depending on whether you must configure a value for that property in your application.
NI-XNET I/O Names in LabVIEW
LabVIEW I/O names (also known as refnum tags) are provided for various object classes within NI-XNET. I/O names provide user interface features for easy configuration.
Error Handling in NI-XNET
Learn how NI-XNET reacts to error conditions in NI-XNET programs.
Displaying Available NI-XNET Interfaces
There are multiple ways, both interactive and programmatic, to view the NI-XNET interfaces that are included in a system.
Creating a Built NI-XNET Application with LabVIEW a Project
NI-XNET supports building applications using LabVIEW projects. You typically distribute these executables to multiple end users, which means you copy the executable to multiple computers (targets).
