Integration von Petrinetzen in den Steuerungsentwurf nach IEC61131.
 Proceedings of the SPS/IPC/Drives 2001, Nürnberg (Germany), pp. 197-205,  Nov. 2001.
-           We present signal interpreted Petri nets (SIPN) as a language  for the transparent description of sequential and concurrent control  algorithms. We show how this new method can be seamlessly integrated  into an IEC 61131 control design environment. A graphical editor for the  development of SIPN-controllers is presented. As a Java Applet the  editor runs on virtually any platform. It returns IL-Code according to  IEC 61131-3, which can be copied into most PLC programming tools. Using  infoteams controller design environment OpenPCS, a direct coupling to  the editor has been prototyped. This connection allows the online  visualization of the programs state by the SIPN editor.
