Abstract
A polling loop system provides all products to be prewired to the polling loop by technically unskilled labor followed by a plug and play enrollment process. The system combines the advantages of DIP switch zone addressing with smart serial number (S/N) addressing, which simplifies installation and replacement requirements. The system is fully backward compatible and is intended for a next generation of commercial polling loop systems.
