I have 4 brand new cDAQ-9132 systems that are going into production thgis week. During the last two weeks as these systems are running, they are crashing. Here is what happens.
1 The system is running our application, or in some cases, just sitting there running Windows 7
2 The screen goes dark, and there is no further response from the system. The power light on the controller is ON.
Restarting the monitor does nothing, unplugging and reinserting the VGA does nothing. No keyboard response at all.
3 Press the RESET button or cycle power using the Power button will restart the computer. Windows error logs have no information at all at the moment of crash, all clean up until the new log entries at boot up.
One odd thing about the setup is that there are very long VGA and USB cables. 16 feet. Two USB cables go 16 feet each to two separate powered USB hubs. One hub has a touchscreen and keyboard, the other hub has a barcode scanner and a label printer.
Four of these systems all have the same symptom. All four racks have one 9229 and one 9422 each.
I setup the bios on one to report USB overcurrent to the OS, and to remain OFF if there is a power interruption. We used a Fluke using Min/Max to check for variability on the 24VDC power supplies used for the controller, nothing was found. The controller has it's own dedicated power supply. Due to a quirk of ordering, two of the system have one type of 24V supply, the other two systems have a different vendor supply. All supplies are more than adequate for the controller.
Any help you can provide is greatly appreciated!
