Identifying communication errors
GUID-4C589FC4-B122-4F12-8E3D-1B05B4FC5FCE v8
Communication errors are normally communication interruptions or
synchronization message errors due to communication link breakdown.
•
Check the IEC61850 and DNP3 communication status in internal event list in
Main menu/Diagnostics/IED Status/General
.
•
In case of persistent faults originating from IED's internal faults such as
component breakdown, contact ABB for repair or replacement actions.
8.1.4.1
Checking the communication link operation
GUID-A1815C16-1AB7-4DEE-8E9B-0BF91DDEE72C v9
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/Diagnostics/Communication/Ethernet status/Front port/
FRONTSTATUS:1
.
Check that the
LinkStatus
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 ports via the LHMI in
Main
menu/Diagnostics/Communication/Ethernet status/Access points
The communication ports on the rear side of the IED are for optical Ethernet
via ST connectors.
•
Check that the
LinkStatus
value is 1, that is, the communication is
working. When the value is 0, there is no communication link.
8.1.4.2
Checking the time synchronization
GUID-CE54512E-06E3-4255-823C-1ACA122CC67E v6
•
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
.
