Hi all, I have a DAQMX Physical Channel control connected to a DAQMX Create Channel (digital out). The channal control give you options for each line, for example, cDAQ1Mod4/port0/line4, but I want an option with a set of lines (without having to type it in). Is there a way to put a range of line such as cDAQ1Mod4/port0/line0:7 as an option? I don't want to require the user to have the knowledge to do that. Also, I don't want to required to user to know what the DAQ number and what the module are before running the test. For example, cDAQ1 is "tester1" and module4 is "digitial out 12V", and I want to put these option on the UI as check box, and I built the physical channel value in the program to feed into DAQMX Create Channel. How do I do that?

Use an enum control on your front panel and write whatever text you want as the descriptions for the channels. On the block diagram use the integer value of the enum to index into an array of DAQmx Physical Channel constants. Richard

Multifunction DAQ

String to DAQMX Physical Channel

Solved!

Hello,

I am trying to do the same thing but when I connect the index array to the Physical Channel the line breaks and I get the error "You have connected two terminals of different types". Also from the phot you can see that the Physical channel VI has no output termnial where I can feed it into the create vi. How do I also change that?

It could be a case that the array constant is not of DAQmx physical channel and hence the broken wire.
