Attributes Documentation

default_initial_state = 5¶

disabled_or_enabled¶

Return True if the summary state is State.DISABLED or State.ENABLED.

This is useful in handle_summary_state to determine if you should start or stop a telemetry loop, and connect to or disconnect from an external controller

domain¶

enable_cmdline_state = False¶

m1CoversClosing¶: Are the M1 covers closing?

m1CoversOpening¶: Are the M1 covers opening?

m1VentsClosing¶: Are the M1 vents closing?

m1VentsOpening¶: Are the M1 vents opening?

require_settings = False¶

simulation_help = None¶

simulation_mode¶

Get the current simulation mode.

0 means normal operation (no simulation).

Raises

ExpectedError: If the new simulation mode is not a supported value.

summary_state¶: Get the summary state as a State enum.

valid_simulation_modes = [1]¶

version = 'v0.5.0'¶

Methods Documentation

classmethod add_arguments(parser)¶

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, kwargs)¶

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, **kwargs)¶

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='')¶

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)¶

Begin do_disable; called before state changes.

Parameters

dataDataType: Command data

async begin_enable(data)¶

Begin do_enable; called before state changes.

Parameters

dataDataType: Command data

async begin_exitControl(data)¶

Begin do_exitControl; called before state changes.

Parameters

dataDataType: Command data

async begin_standby(data)¶

Begin do_standby; called before the state changes.

Parameters

dataDataType: Command data

async begin_start(data)¶

Begin do_start; called before state changes.

Parameters

dataDataType: Command data

async close(exception=None, cancel_start=True)¶

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.

async closeCellVents()¶: Close the M1 vents.

async closeM1Covers()¶: Close the M1 covers.

async close_tasks()¶: Shut down pending tasks. Called by close.

configure(m1_covers_close_time=20, m1_covers_open_time=20, cell_vents_close_time=5, cell_vents_open_time=1, m1_pressure=5, m2_pressure=6, main_pressure=10, cell_load=100)¶

Configure the CSC.

Parameters

m1_covers_close_timefloat: Time to close M1 mirror covers (sec)

tracebackstr, optional: Description of the traceback, if any.

async handle_summary_state()¶

Called when the summary state has changed.

Override to perform tasks such as starting and stopping telemetry (example).

Deprecated. See simulation mode for details.

Parameters

simulation_modeint: Requested simulation mode; 0 for normal operation.

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

async openM1Covers()¶: Open the M1 covers.

put_log_level()¶: Output the logLevel event.

report_summary_state()¶

Report a new value for summary_state, including current state.

Subclasses may wish to override for code that depends on the current state (rather than the state transition command that got it into that state).

set_cell_vents_events(closed, opened)¶

Set m1VentsLimitSwitches, m1VentsPosition and cellVentsState events.

Output any changes.

Parameters

closedbool: Are the closed switches active?

async start()¶

Finish constructing the CSC.

Call set_simulation_mode. If this fails, set self.start_task to the exception, call stop, making the CSC unusable, and return.
Call handle_summary_state and report_summary_state.
Set self.start_task done.

async telemetry_loop()¶

Output telemetry and events that have changed

Notes

Here are the telemetry topics that are output:

m1AirPressure
