7.1.3.1
Checking the communication link operation
There are several different communication links on the product. First check that all
communication ports that are used for communication are turned on.
To check that optical serial port hardware is working, check the
optical fibres for light. Do not look directly into the transmitter since
the direct light can be harmful for the eyes. Point the fibre or
transmitter towards a surface where it is possible to observe when the
light is on. To turn on the transmitter although there is no actual
communication, set
revPolarity
in
Main menu/Configuration/
Communication/IEC60870-5-103/General
to "On".
1.
Check the front communication port RJ-45.
1.1. Check that the uplink LED is lit with a steady green light.
The uplink LED is located on the LHMI above the RJ-45 communication
port on the left. The port is used for direct electrical communication to a PC
connected via a crossed-over Ethernet cable.
1.2. Check the communication status of the front port via the LHMI in
Main
menu/Monitoring/Ethernet/Front port
.
Check that the "LINKUP" value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
2.
Check the communication status of the rear port X0 via the LHMI in
Main
menu/Monitoring/Ethernet/LAN1
.
The X0 communication port on the rear side of the IED is for electrical
communication to a PC connected via a crossed-over Ethernet cable. This
communication port is an alternative to the front communication port.
•
Check that the "LINKUP" value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
3.
Check the communication status of the rear port X1 via the LHMI in
Main
menu/Monitoring/Ethernet/LAN1
.
The X1 communication port on the rear side of the IED is for optical Ethernet via
LC connector or electrical via RJ-45 connector of the IEC 61850-8-1 station bus
communication.
•
Check that the "LINKUP" value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
7.1.3.2
Checking the time synchronization
•
Select
Main menu/Monitoring/IED status
and check the status of the time
synchronization on
Time Synch
.
The
Time synch
value is "Ready" when the synchronization is in order.
