OPAL-RT’s DNP3 Master I/O interface allows connecting with DNP3 slave(s) and read/write analog and binary data points. The read operation can be configured either in polling mode or in unsolicited response mode. Using a standard network interface card, this protocol can be easily and rapidly integrated into any simulation model.
DNP3 is an open and public protocol developed with the aim to to achieve open, standards-based Interoperability between substation computers, RTUs, IEDs (Intelligent Electronic Devices) and master stations (except inter-master station communications) for the electric utility industry. It is now used across several industries.
