Diagram ControllerTree

ControllerTree

The ControllerTree is the central element of a UP application. It is used to divide a machine process into functional units, so-called Controller. The tree defines a hierarchy in which the higher-level controllers communicate with the lower-level controllers. Communication takes place via the controller interface. The subordinate controllers (child) are commanded by the higher-level controllers (parent). The ControllerTree exists in a project only once.

BaseControllerTree

abstract class BaseControllerTree extends NamedResource, DatatypeLibraryOwner

Level

The hierarchy of the ControllerTree is defined by levels. The number of levels used is not limited. Within the levels the controller is instantiated.

The usual levels are defined as follows:

Level 4, Top Level: MAIN controllers and "general services" like HMI, Filehandler, ... which have nothing to do with the control function.

Level 3, Group: Group controller, strongly machine-related, head of an entire function group.

Level 2, module: Modules which perform a corresponding function in a group can also be instantiated several times within group or within a whole machine.

Level 1, Element group: Smallest group of similarities, summary of simple element controllers, which do not necessarily have to be addressed separately.

Level 0, Element: Lowest level of the controller, fulfills exactly one task, reusable, interface to the hardware.

Driver, Driver: Hardware-specific configuration, interface between element controller and hardware (typical application for controllers with motion tasks -> controller is identical, drivers differ depending on the drive used).

ControllerInstance

The ControllerInstance is an instance of a controller. A controller is instantiated in the ControllerTree.

The controller instance is the application-specific version of the corresponding controller. In the context of the ControllerTree, various elements are defined which define the uniqueness.

UserObjectWrapper

The UserObjectWrapper can be used to call function blocks outside the controller construct. Relations can be drawn from any controller. The UserObjectWrapper also has two Code Snippet regions. One for the initialization and one for a cyclic call.
