Use the DAQ assistant included with DAQmx libraries to start. You can find it in the diagram's functions palette "NI Measurements"-> "DAQmx - Data Acquisition" -> DAQ Assistant (left bottom corner). Once you have configured the measurement with the assistant. Now open the front panel by right click on the DAQ assistant icon on the diagram and choose "Convert". Now you can see how the measurement has to be programmed with DAQmx drivers. The resolution of the 6220 card is 16bit. So, if you select a range from -5 to 5 Volts the resolution is 10 Volts divided by 65536 = 152,5

It not possible to run the NI-6220 card with traditional NI-DAQ. You have to use the DAQmx driver, as best in version 7.4. Here you can configure most NI cards in the MAX even by simulation. Once created you can open a test panel to play with the hardware. As an easy programming start, use the DAQ assistant included with DAQmx libraries. Wolfram

I found no password protection in these VIs.

There ist a VI already in the vi.lib. -> "Open a Document on Disk.vi" Can be found here: ...\LabVIEW 7.1\vi.lib\platform\browser.llb Wolfram

You have to select the right data type. Is the type of local "Locals.nom_test" a string? Select the right type by right click on the subVI. Regards Wolfram

Use this as a start Download File:post-1013-1122317126.vi

On this I see that you use a DAQ card that holds only one DMA channel. Use the channel property data transfer mechanism: -> Interrrupts for AO -> DMA for AI This should work fine. See the attachment. Regards

Did you know that it is also possible to use the VIs inside an executable in new VIs. Simple use the "Select a VI" to drop into the diagram. So, it is possible to read out data from sub-VIs that the author of the executable want to never appear. You can read even the connectors and context help of the dropped VIs. This works even, if the front panel of the dropped VI was removed. Hence, spy out of software is supported well. I find that issues very bad.

Creating array of arrays cannot be done directly. Just wrap a cluster around the array and make an array of cluster of arrays. See the attached example. Download File:post-1013-1111010072.vi

I've got some trouble when I run an executable made with 7.1. After updating to LV 7.1.1, the 7.1 executable was not running any more. It was also impossible to install the LV run time engine 7.1 additionally to the run time engine 7.1.1. So I had to rebuild another executable with 7.1.1 in order to fix the problem. But this is not good, because any launched application built with 7.1. may not be running any more, when updating to 7.1.1. :thumbdown:

This can also be set programmatically (see example). Download File:post-1013-1103214564.vi

Hello all, there is a new version of LabVIEW for download on the NI ftp. Look at: ftp.ni.com\support\labview\updates\windows\7.1.1

:worship: Absolutely crazy tool. Many thanks.

I am searching for a strict reference on a formula node. Is there anyone that has one?
