Hello,
My system is a PXIe-1065 chassis (I've also had the same issue in the PXIe-1082 chassis), PXIe-8101 controller with Windows 7 installed by NI, and the following instruments:
DMM PXI-4071, Power Supply PXI-4110, DAQ PXIe-6356, Timing Card PXIe-6674T, and Motion Control PXI-7332.
I also have a PXIe-8361 which I will use on occasion and will be what I use in the long term.
Now for the actual problem. What happens is I'll put together some code in labview using the instrument driver VI's and everything will work fine. I can make VI's that call subVI's that call the instrument VI's and it works great, but if I double click on an instruments VI and then try to look at the block diagram, for example, opening "DAQmx Create Channel (AI-Voltage-Basic).vi" it seems to break the code. Initially it won't say anything but once I hit the run button the arrow will change to the broken gray arrow and will state that the code failed to compile (this is without actually changing anything with the VI, I open it and look at what it is doing).
Also any code I've written that called that VI will now get the same error, if I click show error it will bring up whatever window I was looking at last, so if I was looking at the front panel, then clicked show error it would just bring up the front panel again without highlighting anything. If I create a new file and build a small vi that uses the instrument drivers it works fine, if I copy the vi's from the broken code and paste it into the new file it will fail with the same error.
It doesn't have this behavior with all the instrument VI's but will happen with some. I mentioned it happens with "DAQmx Create Channel (AI-Voltage-Basic).vi" but then it doesn't happen with "DAQmx Timing(Sample Clock).vi". I haven't gone through and checked exactly which VI's it happens with but it seems to happen with other instruments drivers as well, not just for the DAQ. It also only seems to happen when using the PXIe-8101. If I connect it to a computer this issue doesn't pop up. My company primarily controls the chassis using MXI cards so we don't have any available embedded controllers I could swap in to see if it still happens.
It's not a big issue as looking into the instrument vi's isn't necessary for me to do my job, I just do it to try to better understand what exactly is happening but it is something I'm curious about.
