Tool Description

Petri-LLD is a Java program intended to be used to design automation controllers based on Petri-nets. The nets are restricted to one token per place (at most) as this ensures that the resulting systems can be easily translated to run on simple devices such as PLCs (programmable logic controllers). A large number of compiler output types are available, including ladder logic for Omron, Rockwell and Siemens controllers, and also Java and Visual Basic. Also a number of other PLC languages are supported.

This tool has mainly been used to teach students how to construct manufacturing systems. Its main advantage in this is that it allows the student to simulate prior to testing code on the PLC. At the same time, it automatically generates code, so when bugs are found, the student returns to the Petri-LLD tool to both simulate and correct the bug.
