ska_tmc_sdpmasterleafnode.manager.component_manager module
This module implements ComponentManager class for the Sdp Master Leaf Node.
- class ska_tmc_sdpmasterleafnode.manager.component_manager.SdpMLNComponentManager(*args: Any, **kwargs: Any)
Bases:
TmcLeafNodeComponentManager
A component manager for The SDP Master Leaf Node component.
It supports:
Monitoring its component, e.g. detect that it has been turned off or on
Controlling the behaviour of SDP Master.
- disable(task_callback: ska_tango_base.base.TaskCallbackType) Tuple[ska_tango_base.executor.TaskStatus, str]
Submits the Disable command for execution.
- Return type:
tuple
- get_device() ska_tmc_common.device_info.DeviceInfo
Return the device info our of the monitoring loop with name dev_name
- Parameters:
None –
- Returns:
a device info
- Return type:
DeviceInfo
- is_command_allowed(command_name: str) bool
Checks whether this command is allowed. It checks that the device is not in the FAULT and UNKNOWN state before executing the command and that all the components needed for the operation are not unresponsive.
- Returns:
True if this command is allowed
- Return type:
boolean
- off(task_callback: Optional[ska_tango_base.base.TaskCallbackType] = None) Tuple[ska_tango_base.executor.TaskStatus, str]
Submits the Off command for execution.
- Return type:
tuple
- on(task_callback: Optional[ska_tango_base.base.TaskCallbackType] = None) Tuple[ska_tango_base.executor.TaskStatus, str]
Submits the On command for execution.
- Return type:
tuple
- property sdp_master_device_name: str
Returns device name for the SDP Master Device.
- standby(task_callback: Optional[ska_tango_base.base.TaskCallbackType] = None) Tuple[ska_tango_base.executor.TaskStatus, str]
Submits the Standby command for execution.
- Return type:
tuple
- start_communicating() None
Establish communication with the component, then start monitoring.
This is the place to do things like:
Initiate a connection to the component (if your communication is connection-oriented)
Subscribe to component events (if using “pull” model)
Start a polling loop to monitor the component (if using a “push” model)
- stop_communicating() None
Cease monitoring the component, and break off all communication with it.
For example,
If you are communicating over a connection, disconnect.
If you have subscribed to events, unsubscribe.
If you are running a polling loop, stop it.
- update_device_ping_failure(device_info: ska_tmc_common.device_info.DeviceInfo, exception: str) None
Set a device to failed and call the relative callback if available
- Parameters:
device_info (DeviceInfo) – a device info
exception – an exception
- Type:
Exception
- update_ping_info(ping: int, device_name: str) None
Update a device with the correct ping information. :param ping: device response time :type ping: int
