I am working with a ULx labviw driver for a DAQ device from Measurement Computing. The LabVIEW driver calls a DLL. For one of the routine, a physical input is required. However, it is not a daqmx physical channel input. It is something else. I check on he input, and I see a tag that follows it. What type of input is that? I can't find it in LabVIEW, and I can't create it. I can only copy it from another program and paste it to my program. See picture.
Thanks!
Solved! Go to Solution.

Hi,
Thanks! That pointed me to the correct direction. I found a llb that contains the control. However, it is only a control, but not a type def, so I didn't know that the control was stored in a llb until you pointed me to the direction. I attached the controls llb, and I attached another llb that uses the controls. I have some more questions.
1. What type of control is that? I am trying to find it on the pallatte, but I can't. It is bothering me :< If I want to create another one, how do I do that?
2. If you put a vi from the Create Channel.llb on a new vi and right click on the physical channels terminal to create a new control, you will realize you can't do that? What's going on?
It seems to me that the driver that I am using is kind of odd.

It looks like MCC is defining a part of the control functionality in a .NET assembly- I don't have the dll installed)
to get these controls to show up on the palatte you need to import them.
Tools: Import: .NET Controls to Palatte.. and browse to the dlI I'd show pictures but this silly machine doesn't have flash ....yet
Edit- That went faster than I thought it would

For #1, it looks like a Visa Resource name control. Right click on front panel, select I/O pallette, then Visa Resource.

Hi Jeff,
I tried your tip, and I am getting an error that says "you must have the .net framwork 2.0 or later to use .net function and applicatino. Refer to the Microsoft Web site at ...."
I don't understand this error, because my computer has Microsoft .NET Framwork 4.

I think it is different than the one that I am seeing. The one that I am see is not visa based. More on the .Net side.

Intsall >NET. Then install NI-VISA (to provide support for .... yada yada)
Sounds like driver support was installed before ,NET so support for .NET would not be installed

Hi Jeff,
Are you saying that I need to insert my LabVIEW driver's installation DVD and install .NET? Thanks!
