FspModeSubarrayComponentManager Class

class ska_mid_cbf_mcs.fsp_obs_mode.fsp_mode_subarray_component_manager.FspModeSubarrayComponentManager(*args: Any, **kwargs: Any)

Bases: CbfObsComponentManager

A base class component manager for the FspModeSubarray devices.

fhs_health_state_callback(event_data: EventData | None) → None

Callback for FHS device healthState events.

Parameters:

event_data – Tango attribute change event data

start_communicating(*args: Any, admin_mode: AdminMode, **kwargs: Any) → None

Establish communication with the component, then start monitoring.

stop_communicating(*args: Any, admin_mode: AdminMode, **kwargs: Any) → None

Thread for stop_communicating operation.

update_delay_model(model: str) → tuple[list[ResultCode], list[str]]

Update the FSP’s delay model (serialized JSON object)

Parameters:

model – the delay model data

Returns:

A list containing a return code and a string message indicating status. The message is for information purpose only.

subarray_scan_start_time_rounded_callback(event_data: EventData | None)

Callback for subarray<X>ScanStartTimeRounded from the FHS FSP.

Queues up events from the subscribed FHS FSP attribute subarray<X>ScanStartTimeRounded, and will be processed by _update_subarray_scan_start_time_rounded

Parameters:

event_data (Optional[tango.EventData]) – Tango attribute change event data

scan(params: str, task_callback: Callable | None = None, task_abort_event: Event | None = None) → None

Performs the Scan() command functionality

Parameters:

• params – JSON string with input parameters

• task_callback – command tracker update_command_info callback

• task_abort_event – task executor abort event

Returns:

None

end_scan(params: str, task_callback: Callable | None = None, task_abort_event: Event | None = None) → None

Performs the EndScan() command functionality

Parameters:

• params – JSON string with input parameters

• task_callback – command tracker update_command_info callback

• task_abort_event – task executor abort event

Returns:

None

go_to_idle(params: str, task_callback: Callable | None = None, task_abort_event: Event | None = None) → None

Execute observing state transition from READY to IDLE.

Parameters:

• params – JSON string with input parameters

• task_callback – command tracker update_command_info callback

• task_abort_event – task executor abort event

Returns:

None

abort(params: str, task_callback: Callable | None = None, task_abort_event: Event | None = None) → None

Abort the current scan operation.

Due to the obsState model trigger “abort_completed” always transitioning out of ABORTING to ABORTED, this thread must not return until the very end, otherwise the device could successfully transition to ABORTED without issuing a scan abort to sub-devices (refactor in response to SKB-796).

Parameters:

• params – JSON string with input parameters

• task_callback – callback for driving status of task executor’s current LRC task

• task_abort_event – event indicating AbortCommands has been issued

Returns:

None

obs_reset(params: str, task_callback: Callable | None = None, task_abort_event: Event | None = None) → None

Reset the scan operation from ABORTED or FAULT.

Due to the obsState model trigger “obsreset_invoked” only allowing a transition out of ABORTED and FAULT states, and “obsreset_completed” always transitioning out of RESETTING to IDLE, this thread must not return until the very end, otherwise the device could successfully transition to IDLE without properly deconfiguring (refactor in response to SKB-796).

Parameters:

• params – JSON string with input parameters

• task_callback – callback for driving status of task executor’s current LRC task

• task_abort_event – event indicating AbortCommands has been issued

Returns:

None

set_first_output_time(first_output_time: int, task_callback: Callable | None = None, task_abort_event: Event | None = None)

Updates the FSP Mode Subarray’s firstOutputTime attribute and synchronizes firstOutputTime with the FHS FSP devices associated with this FSP Mode Subarray.

Parameters:

• first_output_time – The timestamp value that is to be set by the command

• task_callback – callback for driving status of task executor’s current LRC task

• task_abort_event – event indicating AbortCommands has been issued

Returns:

None
