Hi,

I tested out the sample code provided above. I have a few ideas on what might be happening. I was able to test it with a PXIe-4309, but I did not have a PXI-6284 on hand. I think it is likely that the PXI-6284 does not support the external_calibration_last_time property. And I suspect, the exception is occurring on that resource instead of the PXIe-4309.

I would recommend trying the following things:

  1. Check the property in NI MAX. For example,
    image

  2. Try the following code:

import nisyscfg
with nisyscfg.Session() as session:
    filter = session.create_filter()
    filter.is_present = True
    filter.is_ni_product = True
    for resource in session.find_hardware(filter):
        print(f'{resource.product_name} "{resource.expert_user_alias[0]}"')
        print(f"   Settings")
        print(f"      Name                       {resource.expert_user_alias[0]}")
        print(f"      Vendor                     {resource.vendor_name}")
        print(f"      Model                      {resource.product_name}")
        print(f"      Serial Number              {resource.serial_number}")
        current_temp = resource.get_property("current_temp", None)
        if current_temp is not None:
            print(f"      Current Device Temperature {resource.current_temp:0.1f}")
        external_calibration_last_time = resource.get_property("external_calibration_last_time", None)
        if external_calibration_last_time is not None:
            print(f"   External Calibration")
            print(f"      Calibration Date           {external_calibration_last_time}")

This will produce a report similar to NI MAX. I expect that you'll see Calibration Date listed for PXIe-4309 but not the PXI-6284. Also, find_hardware might be returning some other device that does the external_calibration_last_time property.

Let me know if Calibration Date does not show up for the PXIe-4309.

I hope this helps,

I suspect the PXIe-8301 does not support the expert_user_alias[0] property. However, I did not have the opportunity to test this theory. I am considering adding has_property() to the HardwareResource class in PR #47. Below is an example of the code that leverages this new method and should work with the PXIe-8301 assuming my theory is correct.

import nisyscfg
with nisyscfg.Session() as session:
    filter = session.create_filter()
    filter.is_present = True
    filter.is_ni_product = True
    for resource in session.find_hardware(filter):
        print(f'{resource.product_name} "{resource.name}"')
        print(f"   Settings")
        if resource.has_property("expert_user_alias", index=0):
            print(f"      Name                       {resource.expert_user_alias[0]}")
        print(f"      Vendor                     {resource.vendor_name}")
        print(f"      Model                      {resource.product_name}")
        print(f"      Serial Number              {resource.serial_number}")
        if resource.has_property("current_temp"):
            print(f"      Current Device Temperature {resource.current_temp:0.1f}")
        if resource.has_property("external_calibration_last_time"):
            print(f"   External Calibration")
            print(f"      Calibration Date           {resource.external_calibration_last_time}")

If you would like to try it out, there is a prebuilt wheel under the Artifacts section on https://github.com/tkrebes/nisyscfg-python/actions/runs/3374456755.

For Orderable Part Number property, is this something that you need? I know some drivers report it in NI MAX. Though, it is not currently part of the NI System Configuration API. And in my experience, few drivers implement this property. If you need it, I will see what can be done.

hi TyIer,
I see my screenshot is not on received properly.

after discussion, i understand "Orderable Part Number" is equal for all PXIe-8301. i dont need this parameter.

thanks

i try to run the fixed HardwareResource class from the GitHub

my script:
import nisyscfg
with nisyscfg.Session() as session:
filter = session.create_filter()
filter.is_present = True
filter.is_ni_product = True
for resource in session.find_hardware(filter):
print(f" Settings")
print(f" Resource is present / is device / is ni product = {resource.is_present} / {resource.is_device} / {resource.is_ni_product}")
if resource.has_property("expert_user_alias", index=0):
print(f" Name {resource.expert_user_alias[0]}")
print(f" Vendor {resource.vendor_name}")
print(f" Model {resource.product_name}")
print(f" Serial Number {resource.serial_number}")
if resource.has_property("current_temp"):
print(f" Current Device Temperature {resource.current_temp:0.1f}")
if resource.has_property("external_calibration_last_time"):
print(f" External Calibration")
print(f" Calibration Date {resource.external_calibration_last_time}")

**and receiving the exception, see below. it is trying to query second time at chassis, but resource.is_device response with Fail **

I got a change to look at a system with a PXIe-8301 and a PXIe-109x chassis. I found that find_hardware() returns resources that are not classified as a device or chassis. These resources are not required to support properties like vendor name or product name. I would recommend ignoring resources that are not a device or chassis. The following sample code worked for me on that system.

import nisyscfg
with nisyscfg.Session() as session:
    filter = session.create_filter()
    filter.is_present = True
    filter.is_ni_product = True
    for resource in session.find_hardware(filter):
        if not (resource.is_device or resource.is_chassis):
            continue
        print(f'{resource.product_name} "{resource.expert_user_alias[0]}"')
        print(f"   Settings")
        print(f"      Name                       {resource.expert_user_alias[0]}")
        print(f"      Vendor                     {resource.vendor_name}")
        print(f"      Model                      {resource.product_name}")
        print(f"      Serial Number              {resource.serial_number}")
        current_temp = resource.get_property("current_temp", None)
        if current_temp is not None:
            print(f"      Current Device Temperature {resource.current_temp:0.1f}")
        external_calibration_last_time = resource.get_property("external_calibration_last_time", None)
        if external_calibration_last_time is not None:
            print(f"   External Calibration")
            print(f"      Calibration Date           {external_calibration_last_time}")
