DNP3 Insights | Sumble

What is DNP3?

DNP3 (Distributed Network Protocol) is a set of communications protocols used between components in process automation systems. It is primarily used in utilities such as electric and water companies to communicate between a master station (control center) and remote terminal units (RTUs), intelligent electronic devices (IEDs), or other devices. It is known for its robustness and reliable data transfer, and supports error detection and correction mechanisms, making it suitable for harsh and unreliable communication environments.
