A communication standard for telecontrol and SCADA systems
DNP3 (Distributed Network Protocol version 3) is particularly important in North America due to its wide adoption in the electric power and utility sectors, where reliable, real-time data exchange and control between SCADA master stations and remote terminal units (RTUs) or intelligent electronic devices (IEDs) is essential for efficient and secure operation.
Conformance to DNP3 standard guarantees that devices from different manufacturers can work together seamlessly, enabling interoperability across a wide range of equipment used in these telecontrol and SCADA applications.
