Hi,
In my application, I am using the cRIO 9074 along with the expansion chassis, NI 9144.
I am able to configure the I/O cards on the local chassis, when no hardware is connected
(offline).
But I am unable to configure the expansion chassis.
Is it possible to configure the expansion chassis offline? Or do I need the hardware,
connect it and detect the chassis. Then configure the cards in the expansion chassis.
Thanks & Regards.

Hello,
I have the exact same setup although I do not have access to it today - I'll speak from memory and can answer further questions tonight.
The expansion chassis becomes a target of the 9074. Once configured as a target, modules can be added. I believe these modules can be "virtually" created very similar to the way that is done with the 9074.
I cannot say if the actual expansion chassis itself can be added in this way - you may need to go as far as to have the 9074 and 9144 working together before adding existing or nonexistent c-series modules.
FYI - the modules on the 9144 cannot be targets of the FPGA on the 9074 - They are only targets of the expansion chassis itself and work through the scan engine interface.
Cheers,
