Why Do I Receive Error -1074118592 When Using the niHSDIO Write Named Waveform VI?

Hardware: Digital I/O (DIO)>>High-Speed

Problem:
I am trying to generate a digital waveform using the NI-HSDIO instrument driver and supported hardware. When I use the niHSDIO Write Named Waveform VI I get the following message:

Error -1074118592 occurred at niHSDIO Write Named Waveform (1D U32).vi

Possible reason(s):
Driver Status: (Hex 0xBFFA4040) This read or write function is not supported with the current settings. Ensure that you are using the correct function variant for this device.
If you changed the data width or the data rate multiplier, refer to the documentation for these attributes.



Solution:
This error occurs when you attempt to use a data representation not supported by your current NI-HSDIO-supported device. The number of channels and data width determines which representation can be used be specific devices. The table below shows which data types are supported by specific NI-HSDIO devices:

NI-HSDIO Device	Channels	Data Representation
		WDT	U8	U16	U32
6541	32	√	√	√	√
6542	32	√	√	√	√
6551	20	√	√	√	√
