This paper aims to present a development environment that enables the automatic code generation amenable for the interconnection of components obtained as a result of the partition of a Petri net model addressing its distributed execution using networked controllers (including microcontrollers and FPGAs devices, as well as specific controllers based on PLCs and general purpose PCs). The proposed interconnection solution is based on a Network-on-Chip solution supporting communications based on RS-232 serial protocol (although it can operate at higher transmission rates), for intra-circuit as well as inter-circuits interconnectivity. Being a well-accepted protocol in the industry, the proposed solution integrates existing modules that use the RS232 interface without having to redesign the whole communication system. Implementation platforms used for testing solution include Xilinx reconfigurable platforms, namely Spartan3 and Virtex FPGAs, as well as low cost microcontrollers, namely Microchip PIC18F4620, and general purpose PCs; industrial PCs, PLCs or other platforms with an RS-232 serial port can be easily integrated. A ring topology was selected to allow greater flexibility. The proposed architecture and protocol will be described. Finally, an example will be presented where, starting from the Petri nets model, the flow of development will be presented.
