Problem reading serial number on PXI

[julien_icon-tech]

Hi ,

I'm using LabVIEW to get  access programmatically on hardware informations on my PXI using the System property Node.The informations I'm trying to retrieved are the following.

1. SerialNum
2. ProdName
3. Slot

My actual configuration is 

Slot 0 : Chassis PXIe-1082,SN:305630A

Slot 1 : Controller PXIe-8135, SN:2F25FD89

Slot 5 : PXIe-6674T, SN:00F5929A

Slot 6 : PXI-6683H, SN:0198D955

Slot 8 : PXIe-7971R, SN:01BC305D

This is what I get from the System hardware property node

Slot 0 : Chassis PXIe-1082, SN:305630A

Slot 0 : Controller PXIe-8135, SN:2F25FD89

Slot 1 : Controller PXIe-8135, SN: None

Slot 4 : PXIe-6674T, SN:00F5929A

Slot 5 : PXI-6683H, SN:0198D955

Slot 7 : PXIe-7971R, SN:01BC305D

I can not understand why my controller is appearing on two differents slots  and only one of them has a serial number.Also I find the same behaviour using MAX .

Does anybody came accross this problem before ?

Hi julien,

How are you accessing to your hardware information? Could you attach a screenshot of the MAX information as well as a snippet of your code?

Hi ,

I'm accessing to the hardware information using the System hardware property node. I've linked a  screenshot of my code ,front pannel and MAX .

As you can see on the front panel I'm reading  the PXIe-8135 and serial number on the slot 0  but on MAX I'm detecting the PXIe-8135  on slot 1 with no serial number.

Hi,

Where are you getting your references from? Is this a shipped example? Also I would expect only the active devices to be found and not the 6674T for example.

You could try to reset the MAX Database to eliminate all old configurations (make sure to save the settings beforehand if you would like to load them later)
