class mca_start(*args, **kwargs)

Starts an mca

param_def = [['mca', 'ExpChannel', None, 'mca']]

This property holds the macro parameter description. It consists of a sequence of parameter information objects. A parameter information object is either:

1. a simple parameter object

2. a parameter repetition object

A simple parameter object is a sequence of:

1. a string representing the parameter name

2. a member of Macro.Type representing the parameter data type

3. a default value for the parameter or None if there is no default value

4. a string with the parameter description

Example:

param_def = ( ('value', Type.Float, None, 'a float parameter' ) )

A parameter repetition object is a sequence of:

1. a string representing the parameter repetition name

2. a sequence of parameter information objects

3. a dictionary representing the parameter repetition semantics or None to use the default parameter repetition semantics. Dictionary keys are:

   • min - integer representing minimum number of repetitions or None for no minimum.

   • max - integer representing maximum number of repetitions or None for no maximum.

   Default parameter repetition semantics is { 'min': 1, 'max' : None } (in other words, “at least one repetition” semantics)

Example:

param_def = (
    ( 'motor_list', ( ( 'motor', Type.Motor, None, 'motor name') ), None, 'List of motors')
)

run(mca)

Macro API. Runs the macro. Overwrite MANDATORY! Default implementation raises RuntimeError.

Raises:

RuntimeError

Stops an mca
