Architecture of a retargetable ladder logic diagrams tool

This paper describes the architecture of a retargetable ladder diagram based software tool for programmable logic controllers (PLCs), which is based on the IEC 611311-3 specification. We propose here another approach of rapid prototyping process control with PLCs. The tool is designed in order to support as much as possible many embedded controller platforms or commercial PLCs. It is a cross-platform ladder logic diagram (LLD) tool enhanced by a specific algorithm that optimizes code-time execution.
