Same configuration systems have different device addresses

[mjcohen]

The problem we have is that identically configured systems are sometimes
assigning different device numbers when the systems are booted. Each
individual system always assigns the same device numbers - what puzzles us is that
different systems, although configured identically, assign different device numbers.

More particularly:

Problem Description :

A tester with 4 PXI chassis and 10 PCI cards in an industrial computer
backplane with the same configuration of cards (same instruments in same
slots) on a multi-chassis tester gives different addresses or separate
identical testers under Windows XP. To be clear, this system also has
multiple (10) PCI cards in the industrial computer, as well as the MXI-3
interface to multiple (4) PXI chassis. Under Windows 2000, the device
addressing to all the PCI and PXI cards would remain the same as long as
all the cards were put into the same slots. This problem causes us to
modify our software for each new large industrial tester (called UMATS at
Northrop Grumman).

NI Software : LabVIEW  version 8.2.1
NI Hardware : PXI Controllers, Chassis, and MXI device PXI-8330
Driver Version : MXI-3 1.15
OS : Windows XP

I am not sure if this is applicable or not. I uniquely identify the names of the devices via MAX. In the program. I refer to these names. When I have a new setup, I use MAX to configure the various devices on the deploy machine to their respective names (does not matter what order they are placed in). Run my compile code on the machine without any changes to the program.
