DNP3 Slave
We provide the DNP3 outstation (slave) driver, enabling seamless communication between the simulator and master systems like RTUs, gateways, remote control centers, and SCADA systems.

In this operating mode, the simulator emulates measurements from one or multiple field devices, sending data directly to real master systems. This configuration allows the DNP3 Slave to support realistic testing of supervisory control and data acquisition systems. These systems monitor analog and binary data points, either through continuous polling or by activating unsolicited responses. With unsolicited responses, data is only transmitted when changes are detected, ensuring efficiency. Remote control centers and SCADA systems can send control commands back to the outstation devices.
The DNP3 Slave Simulator helps validate communications workflows in real-time, offering engineers reliable insight into device behavior under various grid conditions. This driver features an asynchronous TCP/IP communication interface and IP aliasing, allowing each outstation instance to have its own IP address, even when using a single physical network interface.
DNP3
DNP3 (Distributed Network Protocol) is an open protocol designed for data transmission over serial and IP communication, widely adopted in the electrical utility industry. It enables seamless monitoring, data acquisition, and control of power system equipment, ensuring interoperability between thousands of IEDs, RTUs, and SCADA systems.

FAQ
Find the answer to your questions
What is the purpose of the DNP3 Slave driver in OPAL-RT simulators?
The DNP3 Slave driver enables the simulators to act as DNP3 Slave devices, allowing seamless communication with master systems such as RTUs, SCADA systems, and control centers for real-time data exchange.
How does the DNP3 Slave Simulator emulate field devices?
The DNP3 Slave Simulator replicates analog and binary data from multiple virtual field devices, transmitting this data to real DNP3 master systems via polling or unsolicited responses for efficient grid communication.
What types of systems can communicate with the DNP3 Slave Simulator?
The DNP3 Slave Simulator supports communication with a wide range of systems including SCADA platforms, RTUs, gateways, and remote control centers through standard DNP3 protocol over TCP/IP.
Does the DNP3 Slave driver support multiple outstation instances?
Yes, the DNP3 Slave driver supports multiple outstation instances using IP aliasing, allowing each instance to be uniquely identified even when operating over a single network interface.
Which OPAL-RT platforms are compatible with the DNP3 Slave and DNP3 Slave Simulator?
The DNP3 Slave and DNP3 Slave Simulator are fully compatible with the RT-LAB and HYPERSIM platforms, providing flexible integration into a variety of real-time simulation environments.
