Configured channels in Measurement Explorer

[Heinrich-Hans]

We have a test system with at least 100 configured digita l IOs and about 30 analog Inputs and Outputs. All channels are configured through the Measurement Explorer using channels names Scale types are applied to the analog Inputs and Outputs.
Reading a analog input with an applied scale type in LabVIEW will result in receiving the scaled data. That's ok.
But now there is one configured analog input with scale type, where LabVIEW completely ignores the configuration. Reading this channel will result in receiving the raw data. Deleting this configuration and reconfigureing this channel has no effect.
Using the builtin testpanel of the Measurement Explorer , I will see the diagram with scaled data.
Does anyone know, what's go
ing on there? Is there a limitation to the number of configurations?

Best regards

first you should use the newest version of NI-DAQ available for your boards. Older version had different problems on scaling data, but the only way to fix this is to install a never version of NI´s driver software.
If you are not sure about the right driver version for your different Boards contact the regular NI Support by phone

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.
