SKAController Tango Device

A generic controller device for SKA.

SKAController inherits from the SKABaseDevice and ControllerInterface, and expects a component manager to be provided by implementing the create_component_manager() method.

Properties

SKAController.GroupDefinitions

Each string in the list is a JSON serialised dict defining the group_name, devices and subgroups in the group. A Tango Group object is created for each item in the list, according to the hierarchy defined. This provides easy access to the managed devices in bulk, or individually.
