A class to handle transition rules for station.

property default_thresholds: dict[str, float]

Get the default thresholds for this device.

Returns:

default thresholds

degraded_rule(station_healths: dict[str, ska_control_model.HealthState | None], subarray_beam_healths: dict[str, ska_control_model.HealthState | None], station_beam_healths: dict[str, ska_control_model.HealthState | None]) → tuple[bool, str][source]

Test whether DEGRADED is valid for the station.

Parameters:

  • station_healths – The healths of the station subdevices.

  • subarray_beam_healths – The healths of the subarray beam subdevices.

  • station_beam_healths – The healths of the station beam subdevices.

Returns:

If the subarray is degraded or not.

failed_rule(station_healths: dict[str, ska_control_model.HealthState | None], subarray_beam_healths: dict[str, ska_control_model.HealthState | None], station_beam_healths: dict[str, ska_control_model.HealthState | None]) → tuple[bool, str][source]

Test whether FAILED is valid for the station.

Parameters:

  • station_healths – The healths of the station subdevices.

  • subarray_beam_healths – The healths of the subarray beam subdevices.

  • station_beam_healths – The healths of the station beam subdevices.

Returns:

If the subarray is failed or not.

healthy_rule(station_healths: dict[str, ska_control_model.HealthState | None], subarray_beam_healths: dict[str, ska_control_model.HealthState | None], station_beam_healths: dict[str, ska_control_model.HealthState | None]) → tuple[bool, str][source]

Test whether OK is valid for the station.

Parameters:

  • subarray_beam_healths – The healths of the subarray beam subdevices.

  • station_beam_healths – The healths of the station beam subdevices.

Returns:

If the subarray is healthy or not.

unknown_rule(station_healths: dict[str, ska_control_model.HealthState | None], subarray_beam_healths: dict[str, ska_control_model.HealthState | None], station_beam_healths: dict[str, ska_control_model.HealthState | None]) → tuple[bool, str][source]

Test whether UNKNOWN is valid for the station.

Parameters:

  • station_healths – The healths of the station subdevices.

  • subarray_beam_healths – The healths of the subarray beam subdevices.

  • station_beam_healths – The healths of the station beam subdevices.

Returns:

If the subarray is in unknown state.
