The RTDS Simulator can exchange data with external hardware or software devices in real time through many different communication protocols. Input and output via Ethernet (though standard-compliant data packets) allows the closed-loop testing of digital substations and other non-wires alternatives.
The RTDS Simulator’s GTNETx2 Network Interface Card provides a real-time communication link to and from the simulated network via different Ethernet-based protocols.
Each GTNETx2 card has two processors which run simultaneously, meaning that two different communication protocols can be run at the same time with one card. Many GTNETx2 cards can be used at once for simulations that may require many streams of the same or different protocols.
Each instance of the GTNET-MODBUS firmware is capable of simulating up to 10 Modbus outstations simultaneously, each with independent data mapping. Each GTNET Modbus outstation can maintain two concurrent communication channels with two different clients, using two different TCP ports (20 connections in total).
Each instance of the GTNET–DNP firmware supports simulation of up to 10 outstations, with a maximum of 2 masters connected per outstation simultaneously (20 connections total), with a maximum polling rate of 5 Hz.
Each firmware can accommodate the following maximum communication capacity:
