CODESYS UML allows to create the application in two languages, the UML class diagram and the UML state diagram.

CODESYS UML is a product that can be purchased with the tool bundle of the CODESYS Professional Developer Edition.

Order number: 



The UML (Unified Modeling Language) is a graphical language for specification, design and documentation of object oriented software. UML provides a generally intelligible discussion basis between programming and other company divisions within system development.

UML consists of 14 different diagram types in two main categories: structure diagrams and behavior diagrams. Structure diagrams schematically illustrate the architecture of software and are basically meant for modeling and analysis (e.g. project design, specification of system requirements or documentation). Behavior diagrams are executable models with distinct syntax and semantics, which directly generate application code („model driven architecture“).

CODESYS UML extends the CODESYS Development System with two new diagrams of the Unified Modeling Language: the class diagram and the state diagram, for the 32 Bit and 64 Bit version of the CODESYS Development System in one package.

Hilfreiches Tool / perfekt integriert / hoher Preis Review by markant
Das Tool erfüllt die Erwartung vollkommen. Man kann sehr schön bestehende Projekte importieren und Änderungen werden beidseitig synchronisiert.
Gute Produkte kosten auch etwas das ist klar. Aber in Anbetracht der Tatsache dass TwinCAT 3 die identische Funktionalität kostenlos bietet finde ich persönlich 1000€ pro Arbeitsplatz sehr hoch. (Posted on 14/09/2017)
