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.
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/Test/Function status/Communication/1:DOSFRNT/Outputs.
Check that the LINKUP value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
The rear port connector X0 is used for connecting an external
HMI to the IED. If the LINKUP value is 0 for front port, there
is no communication link via port X0. Do not use rear port
connector X0 if the IED is equipped with an LHMI.
2. Check the communication status of the rear port X1 via the LHMI in Main
menu/Test/Function status/Communication/1:DOSLAN1/Outputs.
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.

Checking the time synchronization

• Select Main menu/Diagnostics/IED status/General and check the status of
the time synchronization on Time Synch.
The Time synch value is Ready when the synchronization is in order. Note that
the time synchronization source has to be activated. Otherwise the value is
always Ready.

Running the display test

To run the display test, either use the push buttons or start the test via the menu.
• Select Main menu/Tests/LED test.
•
