SKA Dish Master TANGO device server

Abort()

This command aborts the Track or Scan operation when invoked.

AzElOffset

Used by autodoc_mock_imports.

Configure(argin)

Configures the pointing parameters of the dish.

Parameters:argin –
DevString. JSON string consists of Azimuth(decimal degrees), Elevation(decimal degrees)
and receiverBand.

Example:

{
“pointing”: {“AZ”: 1.0,”EL”: 1.0},

”dish”: {“receiverBand”:”1”}

}
Returns:None.

Input from jive: {“pointing”:{“AZ”:1.0,”EL”:1.0},”dish”:{“receiverBand”:”1”}} without any space.

ConfiguredBand

Used by autodoc_mock_imports.

ObsReset()

Currently this command works similar to the Restart command. It clears Dish configuration parameters.

ReceptorNumber

Used by autodoc_mock_imports.

Restart()

This command restarts the Dish.

Scan(argin)

Triggers the dish to start scanning at the set pointing coordinates and capture the data at the input timestamp.

Parameters:argin – DevString. Timestamp in UTC at which command should be executed.
Returns:None
SetMaintenanceMode()

Triggers the Dish to transition into the MAINTENANCE Dish Element Mode. This mode will also enable engineers and maintainers to upgrade SW and FW. Dish also enters this mode when an emergency stop button is pressed.

SetOperateMode()

Triggers the Dish to transition into the OPERATE Dish Element Mode.

Returns:None
SetStandbyFPMode()

Triggers the Dish to transition into the STANDBY-FP (Standby-Full power) Dish Element Mode.

Returns:None
SetStandbyLPMode()

Triggers the Dish to transition into the STANDBY-LP (Standby-Low power) Dish Element Mode. Standby-LP is the default mode when the Dish is configured for low power consumption. It is the mode wherein Dish ends after a start up procedure.

SetStowMode()

Triggers the Dish to transition into the STOW Dish Element Mode. Used to point the dish in a direction that minimises the wind loads on the structure,for survival in strong wind conditions. The Dish is able to observe in the stove position, for the purpose of transient detection.

Slew(argin=0)

Triggers the Dish to move (or slew) at the commanded pointing coordinates.

Parameters:argin – DevString. Timestamp in UTC at which command should be executed.
Returns:None
StartCapture(argin)

Triggers the dish to start capturing the data on the configured band.

Parameters:argin – DevString. Timestamp in UTC at which command should be executed.
Returns:None
StopCapture(argin)

Triggers the dish to stop capturing the data on the configured band.

Parameters:argin – DevString. Timestamp in UTC at which command should be executed.
Returns:None
StopTrack()

This command is created only for making pointingState = 0 in Track command.

Track(argin)

Triggers Track on Dish. It accepts changes in DesiredPointing attribute value and tracks the source. When difference between Achieved and Desired pointing attributes is more than the pointing limits, Dish starts to slewing. Whereas Dish moves in tracking mode, when the difference becomes less than the pointing limits.

Parameters:argin – DevString. Timestamp in UTC at which command should be executed.
Returns:None

Used by autodoc_mock_imports.

check_slew()

Waits until the Dish is slewing and stows it later.

Returns:None
decrement_position(argin)

Decrements the current pointing coordinates gradually to match the desired pointing coordinates.

Parameters:argin – Difference between current and desired Azimuth/Elevation angle.
Returns:None
