How to check in VB code that PXI-system is on and all cards are working.

[jmsa]

My system: Chassis 1010 with MXI8330, 4 x SCXI1129, 2 x PXI2565, 2 x PXI6508 and PXI4021.

Problem: I'm trying to write section of code with Visual Basic which initializes PXI cards and gives information about system(Is it on? What kind of PXI or SCXI cards do I have in my chassis? Are they working?) but I don't know what functions I should call.

Our PXI chassis are not "smart chassis" that have status registers that can give you information like whether or not the chassis is on, but you should be able to pull some information from the cards themselves. This will vary from card to card, and from driver to driver. I would recommend starting with the programmer's reference manuals for the drivers (NI-DAQ, NI-VISA, etc.) and the user manuals for the cards. If the cards do respond, you can infer then that the chassis is on.
