I want to build a realtime sysytem, use one PXIe-8840 ,three PXIe-1075 Chassis ,two PXIe-8381,two PXIe-8384,but some PXI card could not work after I install the software for rt system。When I use only two PXIe-1075, the system is OK. Pls give me some support for MXI use. The software is Labview 2015 Sp1 EN and Driver DCD-Aug16, DAQmx 16.0.

The first troubleshooting step I would try is to put both PXIe-8384s into the same chassis with the PXIe-8840. This will change a couple of things about power on enumeration and may either resolve the problem or give another clue about what's going wrong.

Thanks for reply! As the picture 2 shows, I install two PXIe-8384s in slot 17 and slot 18,and the first PXIe-8384 connect the second chassis and the second PXIe-8384 connect the third chassis. NI MAX also had the same problems. The slot 2,3,4,6,7,8,9 of the second chassis and the slot 8 ,9 of the third chassis are not OK. The PXIe-4300 shows PXIe-4300 "PXI94::0::INSTR" ,and the self test is bad and reset is not work.

if self test goes bad, i suggest you may consider report for damaged device test

I am having the same issue.
I have a PXIe-8880 with three PXIe-1085 chassis.
I am trying to use two PXIe-8384 in the first chassis and extending to PXIe-8381 in the controller slot of the other two Chassis. I can reliably only get one of the two chassis to show in NI MAX.
I have tried updating platform drivers etc on controller and PC with no luck.
I know the controller can see and recognize all modules, but everytime I plug in all three chassis and reboot it can ping for a second while it boots and then is not able to be contacted. Not sure what else to try on the software side.

By moving cards around, I am now able to get all three chassis to show. Now the issue is there is a limit on how many cards I can have installed among all three chassis.
The limit seems to be around 34 cards between all three chassis. Not sure what is limiting this, but adding one more card results in the entire controller being unable to ping and not shown in NI max
