I am learning Labview right now,i saw some sample project them used a lot of DLL file,my question is where i can download these DLL file,like the attached file.

I don't think that is inherently a DLL. It might call a DLL internally, but it looks like it's a VI file without the usual "View as Icon" option ticked, and with the label visible.

Here's an example:

As to where you'll find "Connect Plc.vi", I have no idea. Did someone give you this code? That's not a built-in VI - it's probably a VI someone else has written as part of a project to control a PLC.

Looking at the names of the inputs and outputs, I'd guess it might call a DLL or use a .NET object, in which case you'll also need the appropriate supporting files.

What does LabVIEW search for when you try to open this?
