Section 6: Other Features

6.1

Data Communications

Two communication ports, COM1 and COM2 are provided as standard. RS485 connections are available on the
terminal blocks at the rear of the relay (COM1). A USB port, COM 2, is provided at the front of the relay for local
access using a PC.
Optionally, additional communication ports are available: -
2 x fibre optic communication serial ports with ST connectors (COM 3 and COM 4) plus 1 x IRIG B
1 RS232 serial port (COM 3) plus IRIG B
1 x RS485 serial port (COM 3) plus IRIG B
2 x Electrical Ethernet with RJ45 connectors IEC 61850 - (COM 3 and COM 4),
2 x Optical Ethernet Duplex LC connectors IEC 61850 - (COM 3 and COM 4).
Communication is compatible with Modbus-RTU, IEC60870-5-103 FT 1.2, DNP 3.0, and IEC60870-5-101
transmission and application standards for all serial ports and IEC 61850 for Ethernet ports.
Reydisp Manager provides the functionality of Reydisp Evolution and also provides project management of
multiple devices to allow engineering of IEC61850 projects
Communication with the relay from a personal computer (PC) is facilitated by the REYDISP EVOLUTION
software package. The program allows the transfer of relay settings, waveform records, event records, fault data
records, Instruments/meters and control functions. REYDISP EVOLUTION is compatible with IEC60870-5-103.
Data communications operation is described in detail in Chapter 4 of this manual.
6.2

IEC 61850 Communications

The relay can optionally be provided with IEC61850 comms.
The 61850 comms can be user configured to provide HSR, PRP and RSTP operation.
