1. Overview of the Dupline System
The Dupline fieldbus is a highly versatile, low-cost, and noise-resistant industrial communication system developed by Carlo Gavazzi. Unlike conventional fieldbuses that require complex wiring and configuration, Dupline stands out for its two-wire transmission, capable of carrying both power and data across long distances.
This simple yet robust design allows easy integration of sensors, actuators, switches, and indicators into a unified control network. The system supports multiple network topologies, including ring, star, and tree, allowing engineers to design flexible architectures suitable for various industrial processes.
With decades of proven reliability, Dupline technology has been successfully applied in power plants, process industries, water treatment facilities, and building automation systems. The G389100 series further extends this legacy by integrating Dupline communication with modern protocols like PROFIBUS-DP, Modbus RTU, and Ethernet.
