Constructor for a device

Parameters:

  • deviceId (int) – ID of the device

  • model (str) – Model of the device

  • canbus (CANBus) – CANbus the device is on

property device_id: int

Gets the ID of this device.

Returns:

ID of this device

property control_request: SupportsSendRequest

Get the latest applied control.

Returns:

Latest applied control

property is_connected: bool

Returns whether the device is still connected to the robot. This is equivalent to refreshing and checking the latency of the Version status signal.

Returns:

True if the device is connected

optimize_bus_utilization(optimized_freq_hz: phoenix6.units.hertz = 4.0, timeout_seconds: phoenix6.units.second = 0.1) → phoenix6.status_code.StatusCode

Optimizes the device’s bus utilization by reducing the update frequencies of its status signals.

All status signals that have not been explicitly gven an update frequency using BaseStatusSignal.set_update_frequency will be slowed down. Note that if other status signals in the same frame have been given an update frequency, the update frequency will be honored for the entire frame.

This function only needs to be called once on this device in the robot program. Additionally, this method does not necessarily need to be called after setting the update frequencies of other signals.

To restore the default status update frequencies, call reset_signal_frequencies. Alternatively, remove this method call, redeploy the robot application, and power-cycle the device on the bus. The user can also override individual status update frequencies using BaseStatusSignal.set_update_frequency.

Parameters:

  • optimized_freq_hz (hertz, optional) – The update frequency to apply to the optimized status signals. A frequency of 0 Hz will turn off the signals. Otherwise, the minimum supported signal frequency is 4 Hz (default).

  • timeout_seconds (second, optional) – Maximum amount of time to wait for each status frame when performing the action

Returns:

Status code of the first failed update frequency set call, or OK if all succeeded.

Return type:

StatusCode

static optimize_bus_utilization_for_all(*devices: phoenix6.hardware.traits.common_device.CommonDevice | list[phoenix6.hardware.traits.common_device.CommonDevice], optimized_freq_hz: phoenix6.units.hertz = 4.0) → phoenix6.status_code.StatusCode

Optimizes the bus utilization of the provided devices by reducing the update frequencies of their status signals.

All status signals that have not been explicitly given an update frequency using BaseStatusSignal.set_update_frequency will be slowed down. Note that if other status signals in the same status frame have been given an update frequency, the update frequency will be honored for the entire frame.

This function only needs to be called once in the robot program for the provided devices. Additionally, this method does not necessarily need to be called after setting the update frequencies of other signals.

To restore the default status update frequencies, call reset_signal_frequencies_for_all. Alternatively, remove this method call, redeploy the robot application, and power-cycle the devices on the bus. The user can also override individual status update frequencies using BaseStatusSignal.set_update_frequency.

This will wait up to 0.100 seconds (100ms) for each status frame.

Parameters:

  • devices (tuple[CommonDevice | list[CommonDevice], ...]) – Devices for which to optimize bus utilization.

  • optimized_freq_hz (hertz, optional) – The update frequency to apply to the optimized status signals. A frequency of 0 Hz will turn off the signals. Otherwise, the minimum supported signal frequency is 4 Hz (default). This must be specified using a named parameter at the end of the parameter list.

Returns:

Status code of the first failed optimize call, or OK if all succeeded

Return type:

StatusCode

reset_signal_frequencies(timeout_seconds: phoenix6.units.second = 0.1) → phoenix6.status_code.StatusCode

Resets the update frequencies of all the device’s status signals to the defaults.

This restores the default update frequency of all status signals, including status signals explicitly given an update frequency using BaseStatusSignal.set_update_frequency and status signals optimized out using optimize_bus_utilization.

Parameters:

timeout_seconds (second, optional) – Maximum amount of time to wait for each status frame when performing the action

Returns:

Status code of the first failed update frequency set call, or OK if all succeeded.

Return type:

StatusCode

Resets the update frequencies of all the devices’ status signals to the defaults.

This restores the default update frequency of all status signals, including status signals explicitly given an update frequency using BaseStatusSignal.set_update_frequency and status signals optimized out using optimize_bus_utilization_for_all.

This will wait up to 0.100 seconds (100ms) for each status frame.

Parameters:

devices (tuple[CommonDevice | list[CommonDevice], ...]) – Devices for which to restore default update frequencies.

Returns:

Status code of the first failed restore call, or OK if all succeeded

Return type:
