Notes

Simulation Modes

Supported simulation modes:

  • 0: regular operation

  • 1: simulation mode: start a mock TCP/IP MTDome controller and talk to it

  • 2: simulation mode: talk to a running TCP/IP MTDome controller

In simulation mode 0, the site specific configuration will be sent to the MTDome controller. In both simulation modes 1 and 2, a configuration with mock devices will be sent to the MTDome controller. This allows for testing and/or debugging the MTDome CSC.

Methods Documentation

classmethod add_arguments(parser: ArgumentParser) None

Add arguments to the parser created by make_from_cmd_line.

Parameters
parserargparse.ArgumentParser

The argument parser.

Notes

If you override this method then you should almost certainly override add_kwargs_from_args as well.

classmethod add_kwargs_from_args(args: Namespace, kwargs: dict[str, Any]) None

Add constructor keyword arguments based on parsed arguments.

Parameters
argsargparse.Namespace

Parsed command.

kwargsdict

Keyword argument dict for the constructor. Update this based on args. The index argument will already be present if relevant.

Notes

If you override this method then you should almost certainly override add_arguments as well.

async classmethod amain(index: int | enum.IntEnum | bool | None, **kwargs: Any) None

Make a CSC from command-line arguments and run it.

Parameters
indexint, enum.IntEnum, True, or None

If the CSC is indexed, do one of the following:

  • Specify True to make index a required command-line argument that accepts any nonzero index.

  • Specify an enum.IntEnum class to make index a required command-line argument that only accepts the enum values.

  • Specify a non-zero integer to use that index. This is rare; if the CSC is indexed then the user should usually be allowed to specify the index.

If the CSC is not indexed, specify None or 0.

**kwargsdict, optional

Additional keyword arguments for your CSC’s constructor.

assert_enabled(action: str = '') None

Assert that an action that requires ENABLED state can be run.

Parameters
actionstr, optional

Action attempted. Not needed if this is called at the beginning of a do_... method, since the user will know what command was called.

async begin_disable(data: BaseMsgType) None

Begin do_disable; called before state changes.

Parameters
dataDataType

Command data

async begin_enable(data: BaseMsgType) None

Begin do_enable; called before state changes.

Parameters
dataDataType

Command data

async begin_exitControl(data: BaseMsgType) None

Begin do_exitControl; called before state changes.

Parameters
dataDataType

Command data

async begin_standby(data: BaseMsgType) None

Begin do_standby; called before the state changes.

Parameters
dataDataType

Command data

async begin_start(data: BaseMsgType) None

Begin do_start; configure the CSC before changing state.

Parameters
datacmd_start.DataType

Command data

Notes

The override field must be one of:

  • The name of a config label or config file

  • The name and version of a config file, formatted as <file_name>:<version>, where the version is a git reference, such as a git tag or commit hash. This form does not support labels.

async cancel_periodic_tasks() None

Cancel all periodic tasks.

async check_all_commands_have_replies() None

Check if all commands have received a reply.

If a command hasn’t received a reply after at least _COMMANDS_REPLIED_PERIOD seconds, a warning is logged.

If a command hasn’t received a reply after at least 2 * _COMMANDS_REPLIED_PERIOD seconds, an error is logged and the command is removed from the waiting list.

async check_errors_and_send_events(llc_name: str, llc_status: dict[str, Any]) None
async check_for_duplicate_heartbeat(num_messages: int = 5) int

Monitor heartbeat events and return True if any have a different private_origin.

Intended for use by check_if_duplicate.

The heartbeat loop should be running before this is called. This avoids the issue that if 2 CSCs are started at the same time then neither will see the other one’s heartbeat. This code also assumes that will be true; it will likely raise asyncio.TimeoutError if not.

Parameters
num_messagesfloat

The number of heartbeat messages to read.

Returns
originint

private_origin field of duplicate heartbeat, or 0 if none detected.

Raises
asyncio.TimeoutError

If no heartbeat seen within the specified time.

async close(exception: Exception | None = None, cancel_start: bool = True) None

Shut down, clean up resources and set done_task done.

May be called multiple times. The first call closes the Controller; subsequent calls wait until the Controller is closed.

Subclasses should override close_tasks instead of close, unless you have a good reason to do otherwise.

Parameters
exceptionException, optional

The exception that caused stopping, if any, in which case the self.done_task exception is set to this value. Specify None for a normal exit, in which case the self.done_task result is set to None.

cancel_startbool, optional

Cancel the start task? Leave this true unless calling this from the start task.

Notes

Removes the SAL log handler, calls close_tasks to stop all background tasks, pauses briefly to allow final SAL messages to be sent, then closes the dds domain.

Deprecated. See simulation mode for details.

Parameters
simulation_modeint

Requested simulation mode; 0 for normal operation.

Raises
ExpectedError

If simulation_mode is not a supported value.

is_moveAz_same_as_current(position: float, velocity: float) bool

Is the received moveAz command the same as the current moveAz command or not.

Parameters
positionfloat

The target position to move to.

velocityfloat

The velocity at which the target position is moving.

Returns
bool

True if the issues moveAz command is the same as the current moveAz command or False otherwise.

Notes

The moveAz command is regarded to be the same as the current one if and only if the position is the same and the velocity is 0.0. In all other cases the command is regarded not to be the same. This is important because, if the velocity != 0.0, the dome is following a moving target and the chance of it being at exactly the commanded position with the commanded velocity can be considered zero and therefore the moveAz command has to be sent to the dome.

The very first moveAz command, when connecting to the low-level controller, always is executed, even if the position matches the current position of the dome. The risk of causing vibrations in this case is so low that it doesn’t warrant the hassle of reading the telemetry and determining if it is safe to execute the moveAz command.

The tolerance for the position is 0.25 deg as specified in LTS-97. The tolerance for the velocity is set to a small but non-zero value. See lsst.ts.mtdome.enums for more information.

classmethod make_from_cmd_line(index: int | enum.IntEnum | bool | None, check_if_duplicate: bool = False, **kwargs: Any) BaseCsc

Construct a CSC from command line arguments.

Parameters
indexint, enum.IntEnum, True, or None

If the CSC is indexed, do one of the following:

  • Specify True to make index a required command-line argument that accepts any nonzero index.

  • Specify an enum.IntEnum class to make index a required command-line argument that only accepts the enum values.

  • Specify a non-zero integer to use that index. This is rare; if the CSC is indexed then the user should usually be allowed to specify the index.

If the CSC is not indexed, specify None or 0.

check_if_duplicatebool, optional

Check for heartbeat events from the same SAL name and index at startup (before starting the heartbeat loop)? The default is False, to match the BaseCsc default. Note: handled by setting the attribute directly instead of as a constructor argument, because CSCs may not all support the constructor argument.
