DNP3 Master
Our DNP3 Master I/O interface connects directly with DNP3 slave devices for straightforward read/write access to analog and binary data points. Configure read operations in either polling mode or unsolicited response mode. With a standard network interface card, this protocol integrates quickly and easily into any simulation model.
About DNP3
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.

FAQ
Find the answers to your questions
What is a DNP3 Master and how does it work in real-time simulation?
A DNP3 Master is a control device or application that communicates with DNP3 slave devices to read and write data points like analog inputs or binary outputs. In our simulation environment, the DNP3 Master software provides seamless integration with slave devices via a standard NIC, enabling quick setup and accurate testing of communication flows in both polling and unsolicited response modes.
Can I use OPAL-RT’s DNP3 Master with any DNP3 slave device?
Yes, our DNP3 Master I/O interface is fully compatible with a wide range of DNP3 slave devices. It supports standard DNP3 protocol functionality, allowing for reliable read/write access across multiple platforms, including RT-LAB and HYPERSIM.
What is a DNP3 Master Simulator and how is it different from a real master device?
A DNP3 Master simulator emulates the behavior of a physical master station, enabling testing and validation without needing real hardware. Our real-time simulation platforms act as high-fidelity DNP3 Master simulators, ideal for development, testing, and troubleshooting of DNP3 slave communication in a safe, virtualized environment.
What kind of DNP3 Master software does OPAL-RT provide?
Our DNP3 Master software is a built-in I/O interface that supports real-time read and write operations to DNP3 slave devices. It is designed for ease of configuration, offering both polling and unsolicited modes, and integrates smoothly with your simulation model using a standard network interface card.
How does the DNP3 Master handle master-slave communication?
The DNP3 Master-slave communication is handled through standardized data exchange protocols, where the master initiates commands and requests, and the slave responds or sends unsolicited data. Our DNP3 Master solution ensures this interaction is precise and synchronized within real-time simulation workflows.
