Hi,
I can't answer your question with the info that you provided, but I'd like to get more infomation from you on the problem.
What version of LV and NI-DAQ are you using?
Are you using Traditional DAQ or DAQmx?
When you say that the channels are "using channels names Scale types" what do you mean? Do you mean using custom scales? Or do you mean that the measurement type is something other than voltage, like temperature?
Is the channel that is giving you the problem on a different device from the ones that are ok? Or is it a different measurement type from the others?
If you are using DAQmx, try this in your LV VI... Drop an I/O name control, select the channel that is giving you a problem. Wire it to a DAQmx Read VI. Create an output for the data
value form the Read VI. Run the VI. Is the reading ok? If not, right click on the i/o control and select "Generate Code > Configuration" and again run the VI. Is this reading ok? If not, take a snapshot of your configuration of this channel in MAX and of your VI diagram and attach them to this post. I'll take a look at what the configuration code is.
