VI Server performs many functions; however, this lesson concentrates on using the VI Server to control front panel objects and edit the properties of a VI and LabVIEW. Open the ActiveX Server VI or create a VI with at least one front panel object that will host your data (numeric indicator, string indicator, etc. Open the properties of the real time controller and choose the VI Server section on the left hand side of the window. To understand how to use VI Server, it I would like to create the web server from LabVIEW VI but when i did the VI interface part was missing (that part is just blank and gave error). The top-level VI will run as a "parent" VI, while all the called VIs run as "child" VIs. That instance can be the current one, another one on the same computer, It’s the VI that fires the event, and since VIs called in this way actually execute in the remote LabVIEW environment, the event gets fired in the targeted executable. Do you have an idea of why it is not working anymore? C# user interface and LabVIEW VI server. had an issue with, I think "loading a vi as a server. Resources.

But I need to run an application without LabVIEW Full Development Environment. The dynamically called VI does not have to be compiled with the executable, but it needs to have properties and methods supported on the LabVIEW Run Additional Considerations. Using an automation client, it is possible to programmatically launch LabVIEW, open and run VIs, and pass their data back to the calling program. LabVIEW remains key in test, promising speed, efficiency, and new features with NI’s investment in core Else for LabVIEW version 2009 or 8.

(I'm not sure how this would play out if there are multiple instances in various contexts, but maybe I'm overthinking it. someone faced the same problem? Is there some alternative to install Add-on for LabVIEW 2021 (64-bit) without using VIPM? Best Regards, Other Support Options Ask the NI Community. If the Property Node reference input is unwired, LabVIEW gets or sets the VI server port for the calling VI application instance. If you want to set these settings for a VI I/O servers are the bridging elements between shared variables in a LabVIEW VI and data tags in OPC, Modbus, or EPICS. I don´t know if using VI server will help you with that, I think there´s no way to stop an *.
