Statechart Elements The elements of the statechart are available in the ToolBox view. This view opens when you open a statechart object in the editor. Start state End state State State (in-cycle) Note
Element: Start state The Start state element represents a pseudo state for an initial state. If the state is at the top level, then the statechart flow starts from there. If it is in a composite state
Element: End state An end state is a pseudo state. It indicates that the execution of the area that contains this end state has ended. End states can be located in a statechart at the top level, in co
Element: State A state is the main element of a statechart. A state machine (or statechart) runs through various states during its runtime and executes their actions. A state can have ENTRY, DO, and E
Element: Fork/Join The fork is a pseudo state to split transitions to pseudo-parallel processing in orthogonal states. All transitions that originate from a fork are completion transitions that have t
Element: Choice A choice is a node in a statechart. The subsequent guard conditions are evaluated at the node within a cycle. It has at least one incoming transition and one outgoing transition. Choic
Class Diagram Elements The elements of the class diagram are available in the ToolBox view. This view opens when you open a Class Diagram object in the editor. Class ( POU ) Interface DUT (Data Unit T
Element: Class A class is a logical unit with encapsulated data and operations. It also represents a variable type that can be instantiated. When the instance of a class is assigned as a variable to a
Element: Interface An interface is a set of methods and property declarations that describe a publicly visible behavior. Thus it does not include any variables or implementation. A specialist relation
