Being able to specify skipping cyclic frames and determining the transmit time of a cyclic frame can be important. For example, assume that you want to create a Signal Input Single-Point session and want the VI end user to select signals from the front panel. The main difference is in the NI VeriStand project setup phase. Once the appropriate NI-XNET port has been added, configure addition settings for the port through the protocols configuration page. You can achieve this in several different ways.

Using LabVIEW project sessions is best suited for static applications, in that the network data does not change from one execution to the next. Right-click the signal list control and select Browse for Database File to nk the database file. What Is an Alias?
NI-XNET Driver and LabVIEW Compatibility
There are two methods for creating a session: Frame Output Stream Mode: There are some notes included in this section below based on the hardware in the system. Want to Use a File?
Using this technique, you can avoid files entirely and make your application self contained. NI VeriStand uses projects to help get up and running quickly. Using the time when the signal frame is transmitted according to the database, resamples the signal data from a waveform with a fixed sample rate.
NI VeriStand provides a framework for real-time testing applications such as embedded software validation and real-time control and monitoring of mechanical test cell applications. Once configured and saved, the application can use a single point session to transmit or receive this frame.
You can create sessions for other input or output modes using the same technique.
A description of each step in the process follows the flowchart. You can choose from two cnet techniques to edit a database file: NI LabVIEW gives you a single environment in which to acquire, analyze, and present your data and it abstracts low-level programming calls.
Frames are messages transmitted across an embedded network. After you browse to xneet file and select a cluster, that information is saved with the VI, so you need to select only signal names from that point onward.
The constant is placed on your block diagram.

Back to Top 4. Signal Input Single-Point Mode: Back to Top 5. When you deploy to a LabVIEW RT target, the large text file is compressed to an optimized binary format, and that binary file is transferred to the target.
Nevertheless, each LIN schedule entry generally fits the xner of cyclic and event timing that are common for other protocols such as CAN and FlexRay.

The VI user selects signals from this tree control. This property specifies the static slot that the session interface uses to transmit a startup frame. The controller specification screen enables NI VeriStand to communicate with ji appropriate device and at the specified target rate. The following three types of Frame Information channels can be accessed: Back to Top 5.

Back to Top 7. In the FlexRay database, two or more hardware products are designated to transmit a special startup frame.
