Section 8 Establishing connection and verifying the
IEC 61850 communication
8.1 Overview
SEMOD172103-4 v8
The rear optical Ethernet ports are used for:
•
process bus (IEC/UCA 61850-9-2LE) communication
• IEEE C37.118/1344 communication
• substation bus (IEC 61850-8-1) communication
8.2 Setting the station communication
SEMOD172108-3 v12
To enable IEC 61850 communication the corresponding ports must be activated.
The rear access points can be used for IEC 61850-8-1 and IEC/UCA 61850-9-2LE
communication. IEC 61850-8-1 redundant communication requires the use of two
Ethernet ports, when it is activated for Ethernet port the next immediate port is
selected as the second Ethernet port and will become hidden.
To enable IEC 61850 station communication:
In this example access points 1, 2 and 3 are used.
1. Activate IEC 61850-8-1 (substation bus) communication.
Navigate to: Main menu/Configuration/Communication/Station
communication/IEC61850–8–1/IEC61850–8–1:1
2. Enable operation for Access Point 1 and 3 in the Ethernet configuration tool
(ECT) in PCM600.
3.
Enable redundant communication for Acess point 1 using ECT.
4. Enable IEC/UCA 61850-9-2LE (process bus) communication for Access
point 3 by connecting it to a Merging unit in the Merging units tab in ECT.
There are no settings needed for the IEC/UCA 61850-9-2LE communication in the
local HMI branch Station communication. Make sure that the optical fibres are
connected correctly. Communication is enabled whenever the merging unit starts
sending data.
