Abstract: 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.
