7SR18 Description Of Operation

Section 6: Other Features

6.1

Data Communications

Two communication ports are provided designated COM1 and COM2. COM1 is a RS485 connection available on
the terminal blocks at the rear of the relay. COM2 is a USB port provided at the front of the relay for local access
using a PC.
Optionally, additional IEC61850 communication ports are available: -
2x Electrical Ethernet with RJ45 connectors IEC 61850 - (COM 3),
2x Optical Ethernet with Duplex LC 100BaseF connectors IEC 61850 - (COM 3)
The COM1 port can be selected to operate as a local or a remote port operation.
Communication is compatible with Modbus-RTU, IEC60870-5-103 FT 1.2 and DNP 3.0 transmission and
application standards.
For communication with the relay via a personal computer (PC) a user-friendly software package, Reydisp
Evolution or Reydisp Manager, is available to allow transfer of relay settings, waveform records, event records,
fault data records, Instruments / meters and control functions. Reydisp is compatible with IEC60870-5-103.
6.2

IEC 61850 Communications

The relay can optionally be provided with IEC61850 comms.
IEC61850 is provided with an added EN100 communication module.
The following EN100 output alarms are provided:
EN100 Life:
EN100 Error:
IEC61850 Configured:
EN100 Ch1 Link Down:
EN100 CH2 Link Down:
For further details refer to the following publications:
Model Implementation Conformance Statement (MICS)
Protocol Implementation Conformance Statement (PICS)
Protocol Implementation Extra Information for Testing (PIXIT)
Unrestricted Page 70 of 78
When the relay is powered up, the EN100 Module initializes with the relay.
When initialization is successful this point becomes true.
During relay operation, if an error occurs with the data communication
between the EN100 module and the relay, this point becomes true. - This
does not specify if there is an error with one of the communication channels
(Link 1/2)
This point will become true when an IEC 61850 station/network has been
configured and the all 61850 associated data has been synchronized to the
relay
When communication is lost on the Channel 1 Ethernet port this point
becomes true.
When communication is lost on the Channel 2 Ethernet port this point
becomes true.
