- The second generation Giga-Transceiver Network Communication Card,or GTNETx2, provides a real time communication link to and from the simulator via Ethernet. Different protocols are used with the GTNETx2 depending on the application. The different protocols, described below in detail, accommodate MODBUS, TCP/UDP socket communication, IEEE C37.118 data output streams, IEC 61850 GSE binary messaging, IEC 61850-9-2 sampled values, DNP3 communication, IEC 60870-5-104 protocol and playback of large data files stored on a PC hard disk.
- In previous generation rack-based systems, the GTNETx2 card is rack-mounted, residing within the RTDS card cage. In NovaCor-based systems, the GTNETx2 card may reside in a specially designed chassis that can be mounted within the NovaCor cubicle. Each GTNET chassis can hold up to 3 GTNETx2 or GTNET cards.
- The GTNETx2 communicates with the simulation through the GT optical port which is connected to a NovaCor chassis or PB5 card.
- Each GTNETx2 card has two modules. Each module has one Ethernet port, which may be equipped for one of three connection options: 100/1000 Copper, 100BASE-FX, or 1000BASE-SX.
