Setting DAQ channel by property node does not display the value

Advertisement

I am writing a configuration VI to set channel selection and calibration parameters for an SCXI chassis. I store a default setup in a configuration (ini) file and read that file automatically when the VI is called. The value from the file are set by property nodes using the "Value" property. The values from the file do not display in the DAQ channel selection rings, but the numerical calibration values do display correctly. When I click the down arrow in the channel rings, the correct value displays.
This behavior exists both in LabView and app-builder EXEs. Also, if I change the property nodes for the DAQ channels to local variables, it works. The Value (signaling) property doesn't cause them to display
properly either. Why can't I use the property node?

I don't understand exactly what you are trying to do.
Please upload a simple VI to demonstrate the behavior you are describing. Remember also to attach the .ini file.
