TwinCAT 3 UML TF1910-0v92

With the integration of UML (Unified Modeling Language) in TwinCAT 3.1, two additional editors for modeling of PLC software are available. The existing TwinCAT PLC programming languages are extended with the UML class and UML state diagrams. UML in general UML is a graphical language for software analysis, design and documentation. UML is particularly suitable for object-oriented implementations. The unified modeling of the PLC application results in easy to follow software documentation, which lends itself to analysis and discussion by non-programming specialists. UML diagrams in TwinCAT 3.1 PLC The UML class diagram belongs to the group of UML structure diagrams and can be used for schematic representation of the software architecture: Object classes, elements contained within them and object relationships can be represented in a transparent manner. The UML state diagram is part of the UML behavior diagrams and is used for dynamic software modeling. It can be used for a graphic specification of the dynamic response or the state-dependent system behavior. Compilation of the state diagram generates program code, so that the state machine can be executed directly. The development process is supported by an online debugging option.
