ctrl

actual controller object

get_ctrl_info()

ctrl_info

controller information object

set_operator(operator)

Defines the current operator object for this controller. For example, in acquisition, it should be a PoolMeasurementGroup object.

raw_read_axis_states(axes=None, ctrl_states=None)

Unsafe method. Reads the state for the given axes. If axes is None, reads the state of all active axes.

Parameters:axes (seq<int> or None) – the list of axis to get the state. Default is None meaning all active axis in this controller Returns:a tuple of two elements: a map containing the controller state information for each axis and a boolean telling if an error occured Return type:dict<PoolElement, state info>, bool

read_axis_states(*args, **kwargs)

Reads the state for the given axes. If axes is None, reads the state of all active axes.

Parameters:axes (seq<int> or None) – the list of axis to get the state. Default is None meaning all active axis in this controller Returns:a map containing the controller state information for each axis Return type:dict<PoolElement, state info>

raw_read_axis_values(axes=None, ctrl_values=None)

Unsafe method. Reads the value for the given axes. If axes is None, reads the value of all active axes.

Parameters:axes (seq<int> or None) – the list of axis to get the value. Default is None meaning all active axis in this controller Returns:a map containing the controller value information for each axis Return type:dict<PoolElement, SardanaValue>

read_axis_values(*args, **kwargs)

Reads the value for the given axes. If axes is None, reads the value of all active axes.

Parameters:axes (seq<int> or None) – the list of axis to get the value. Default is None meaning all active axis in this controller Returns:a map containing the controller value information for each axis Return type:dict<PoolElement, SardanaValue>

stop_axes(axes)

Stops the given axes.

Parameters:axes (list<axes>) – the list of axes to stopped. Returns:list of axes that could not be stopped Return type:list<int>

stop_element(*args, **kwargs)

Stops the given element.

Parameters:element (PoolElement) – the list of elements to stop Raises:Exception – not able to stop element

stop_elements(*args, **kwargs)

Stops the given elements. If elements is None, stops all active elements.

Parameters:elements (seq<PoolElement> or None) – the list of elements to stop. Default is None meaning all active elements in this controller Returns:list of elements that could not be stopped Return type:list<PoolElements>

stop(*args, **kwargs)

Stops the given elements. If elements is None, stops all active elements.

Parameters:elements (seq<PoolElement> or None) – the list of elements to stop. Default is None meaning all active elements in this controller Returns:list of elements that could not be stopped Return type:list<PoolElements>

abort_axes(*args, **kwargs)

Aborts the given axes.

Parameters:axes (list<axes>) – the list of axes to aborted. Returns:list of axes that could not be aborted Return type:list<int>

abort_element(*args, **kwargs)

Aborts the given elements.

Parameters:element (PoolElement) – the list of elements to abort Raises:Exception – not able to abort element

abort_elements(*args, **kwargs)

Abort the given elements. If elements is None, stops all active elements.

Parameters:elements (seq<PoolElement> or None) – the list of elements to stop. Default is None meaning all active elements in this controller Returns:list of elements that could not be aborted Return type:list<PoolElements>

abort(*args, **kwargs)

Abort the given elements. If elements is None, stops all active elements.

Parameters:elements (seq<PoolElement> or None) – the list of elements to stop. Default is None meaning all active elements in this controller Returns:list of elements that could not be aborted Return type:list<PoolElements>

emergency_break(*args, **kwargs)

Stops the given elements. If elements is None, stops all active elements. If stop could not be executed, an abort is attempted.

Parameters:elements – the list of elements to stop. Default is None meaning all active elements in this controller Returns:elements that could neither be stopped nor aborted Return type:list<PoolElement>
