Proposal : If left unwired, the DAQmx Create Channel Minimum and Maximum Value inputs would default to the maximum value for whatever physical channel was wired.  Currently for example, AO Voltage defaults to +/- 10 V.  Some devices such as the USB 6008 are limited to 0 to +5 V.  For programs that allow for different daq devices to be used and changed at run time, one does not know ahead of time what the allowable input limits will be and cannot be assigned.  Is it possible to use the DAQmx Device property I/O Type:Analog Output:Voltage:Ranges to obtain the limits and then wire that result however this involves extra coding to make use of them.  If the DAQmx Create Channel is used at many places in a vi it becomes cumbersome to have to extract the property for every instance of use.  i.e. even if DAQmx Create Channel is done once, another call to it does not retain the values previously set.  A solution would be for DAQmx Create Channel to simply obtain the minimum and maximum values based on whatever physical channel was wired to it and use them.
