Data Communications

Overview of Functions

3.7.1
The relay data communication facility is compatible with control and automation systems and PCs running
Reydisp suite of software. The relay can provide the following:
•
Operational information
•
Post-fault analysis
•
Parameter interrogation
•
Device configuration
The device provides 1 front USB communication interface (Com2) on the fascia and 1 RS485 (Com1) on the
rear along with 2 Ethernet ports on the rear. The Ethernet ports can be ordered for connection with Electrical
RJ45 or Optical LC access. The access to the communication settings for the USB port is available from the
front menu structure via the keypad setting menu Communications or through the parameter configuration
PC software.
Communication interface
•
Com2-USB – The Com2-USB port is used for configuring the device with Reydisp software and allows the
updating of firmware.
The Com2-USB port has the IP address 192.168.2.1
•
Com1-RS485 (Terminal Reference X1) – The Com1-RS485 port can be used for DNP3.0, IEC 60870-5-103
or Modbus RTU communications to a substation SCADA, integrated control system, or engineer remote
access.
The port can be independently mapped to the DNP3.0, IEC 60870-5-103 or Modbus RTU protocol or
switched off in the device configuration.
•
Com-Ethernet – 2 electrical (RJ45) ports (Channel 1/Terminal Reference X2 and Channel 2/Terminal Refer-
ence X3) or 2 optical (LC) ethernet ports (Channel 1/Terminal Reference X4 and Channel 2/Terminal
Reference X5).
The Ethernet ports can be used for IEC 61850 communications to a substation SCADA, integrated control
system, or engineer remote access using Reydisp configuration software.
The same protocol can be used simultaneously on both ports.

Structure of the Function

3.7.2
Communication is compatible with transmission and application standards for the serial port and IEC 61850
for Ethernet ports.
The 61850 comms can be user configured to provide HSR, PRP and RSTP operation.
