do()

Initializes the attributes and properties of the Subarray Node.

Returns:A tuple containing a return code and a string message indicating status.

The message is for information purpose only.

Return type:(ReturnCode, str) Raises:DevFailed if the error while subscribing the tango attribute

Used by autodoc_mock_imports.

Track(argin)

Invokes Track command on the Dishes assigned to the Subarray.

activityMessage

Used by autodoc_mock_imports.

always_executed_hook()

Internal construct of TANGO.

calculate_observation_state()

Calculates aggregated observation state of Subarray.

command_class_object()

Sets up the command objects :return: None

delete_device()

Internal construct of TANGO.

get_deviceproxy(device_fqdn)

Returns device proxy for given FQDN.

health_state_cb(event)

Retrieves the subscribed health states, aggregates them to calculate the overall subarray health state.

Parameters:event – A TANGO_CHANGE event on Subarray healthState. Returns:None

init_command_objects()

Initialises the command handlers for commands supported by this device.

is_Track_allowed()

Checks whether this command is allowed to be run in current device state

Returns:True if this command is allowed to be run in current device state Return type:boolean Raises:DevFailed if this command is not allowed to be run in current device state

observation_state_cb(evt)

Retrieves the subscribed CSP_Subarray AND SDP_Subarray obsState.

Parameters:evt – A TANGO_CHANGE event on CSP and SDP Subarray obsState. Returns:None

pointing_state_cb(evt)

Retrieves the subscribed DishMaster health state, aggregate them to evaluate health state of the Subarray.

Parameters:evt – A TANGO_CHANGE event on DishMaster healthState. Returns:None

read_activityMessage()

Internal construct of TANGO. Returns activityMessage. Example: “Subarray node is initialized successfully” //result occured after initialization of device.

read_receptorIDList()

Internal construct of TANGO. Returns the receptor IDs allocated to the Subarray.

read_sbID()

Internal construct of TANGO. Returns the scheduling block ID.

read_scanID()

Internal construct of TANGO. Returns the Scan ID.

EXAMPLE: 123 Where 123 is a Scan ID from configuration json string.

receive_addresses_cb(event)

Retrieves the receiveAddresses attribute of SDP Subarray.

Parameters:event – A TANGO_CHANGE event on SDP Subarray receiveAddresses attribute. Returns:None

receptorIDList

Used by autodoc_mock_imports.

remove_receptors_from_group()

Deletes tango group of the resources allocated in the subarray.

Note: Currently there are only receptors allocated so the group contains only receptor ids.

Parameters:argin – DevVoid Returns:DevVoid

sbID

Used by autodoc_mock_imports.

scanID

Used by autodoc_mock_imports.

validate_obs_state()

write_activityMessage(value)

Internal construct of TANGO. Sets the activityMessage.
