Creating a Python API for PXI Chassis Fan Speed Control #48

Closed nahumpodokshik closed 1 year ago

nahumpodokshik commented 1 year ago

we use nisyscfg-python to remotely collect information about PXIe-1092 chassis fans, cooling profiles, and PXIe-4309 cards temperatures. it is a simple and effective solution for automatically detecting and alerting NI systems requiring immediate service or support. Is it possible to add to the same nisyscfg API the ability to control these fans and configure colling profiling?

thanks and best regards, Nahum

The API should already support for controlling fans. Below is a list of the PXI fan control properties. To control a fan, assign values to the appropriate properties and then invoke save_changes() to commit the settings.

# resource is a HardwareResource to a PXI chassis
resource.pxi.fan_mode  # (read/write) nisyscfg.enums.FanModes              
resource.pxi.fan_user_rpm  # (read/write) int
resource.pxi.supported_fan_modes  # (readonly) nisyscfg.enums.FanModes
resource.pxi.fan_manual_rpm_lower_bound  # (read/write) int
resource.pxi.fan_manual_rpm_upper_bound  # (read/write) int
resource.pxi.cooling_profile  # (read/write) nisyscfg.enums.CoolingProfiles
resource.pxi.cooling_profile_source  # (read/write?) nisyscfg.enums.CoolingProfileSource
resource.pxi.supported_cooling_profiles  # (readonly) nisyscfg.enums.CoolingProfiles
resource.pxi.enable_user_override_of_cooling_profile  # (read/write) bool

# Invoke save_changes() to write and save changes to device
resource.save_changes()

Also in PR #51, I recently changes the data typed returned by the following properties:

The value is an enum.IntFlag instead of a list of enum.IntEnum. Let me know if this change will cause you any trouble.

Hi Tyler,

sorry for the delay was disconnected. we partially evaluated the suggested code. it is working good. my colleague is working to integrate all components together. the solution scans daily all systems in lab, detects "overheat" and will send email/alert and will change colling and FAN settings to cover the issue until maintenance. we use PXIe-1092 chassis. can we use nisyscfg to activate front panel "yellow" LED on chassis to blink?

thanks and best regards!! Nahum
