William,
In the process of trying to recreate your problem, I think I stumbled into the solution.
The Get SCXI Information VI is a traditional DAQ VI. This VI will only
work if you have configured your SCXI chassis for the Traditional DAQ
driver in MAX. Most likely, you have configured the SCXI chassis under
the NI-DAQmx driver and not the Traditional DAQ driver.
Configure the SCXI chassis under the Traditional DAQ driver in
MAX. This involves right clicking Traditional DAQ Devices under
Devices and Interfaces in MAX. Select ADD SCXI Chassis...
and select the proper settings for your devices. The downside to
doing this is that you probably already have code written for the DAQmx
driver and accessing the DAQmx driver at the same time you access the
Traditional DAQ driver can cause problems.
There is no equivalent in the DAQmx driver to the "Get SCXI Infromation.VI".
If you try to use DAQmx VIs and Traditional DAQ VIs at the same time on
the same device and your program starts to crash, reset the drivers
each time you switch from DAQmx to traditional, using the reset device
VIs.
If I am completely off base here, please reply and I will continue to work on the issue.
I hope this helps,
