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:
- parser
argparse.ArgumentParser
The argument parser.
- 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:
- args
argparse.Namespace
Parsed command.
- kwargs
dict
Keyword argument dict for the constructor. Update this based on
args
. The index argument will already be present if relevant.
- args
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:
- index
int
,enum.IntEnum
,True
, orNone
If the CSC is indexed, do one of the following:
Specify
True
to makeindex
a required command-line argument that accepts any nonzero index.Specify an
enum.IntEnum
class to makeindex
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.- **kwargs
dict
, optional Additional keyword arguments for your CSC’s constructor.
- index
- assert_enabled(action: str = '') None ¶
Assert that an action that requires ENABLED state can be run.
- Parameters:
- action
str
, 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.
- action
- async begin_disable(data: BaseMsgType) None ¶
Begin do_disable; called before state changes.
- Parameters:
- data
DataType
Command data
- data
- async begin_enable(data: BaseMsgType) None ¶

- Parameters:
- data
DataType
Command data
- data
- async begin_exitControl(data: BaseMsgType) None ¶
Begin do_exitControl; called before state changes.
- Parameters:
- data
DataType
Command data
- data
- async begin_standby(data: BaseMsgType) None ¶
Begin do_standby; called before the state changes.
- Parameters:
- data
DataType
Command data
- data
- async begin_start(data: BaseMsgType) None ¶
Begin do_start; configure the CSC before changing state.
- Parameters:
- data
cmd_start.DataType
Command data
- 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 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.

- 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.
- 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.

- exception
Exception
, optional The exception that caused stopping, if any, in which case the
self.done_task
exception is set to this value. SpecifyNone
for a normal exit, in which case theself.done_task
result is set toNone
.- cancel_start
bool
, optional Cancel the start task? Leave this true unless calling this from the start task.
- exception
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.
