•
for plastic fibres with connector type HFBR
•
for glass fibres with connectors type ST
Procedure
1.
Set the operation of the rear SPA/IEC port to "IEC".
The operation of the rear SPA/IEC port can be found on the local HMI under Main
menu/Configuration/Communication/SLM configuration/Rear optical SPA-
IEC-DNP port/PROTOCOL:1
When the setting is entered the IED restarts automatically. After the restart the
selected IEC port operates as an IEC port.
2.
Set the slave number and baud rate for the rear IEC port.
The slave number and baud rate can be found on the local HMI under Main menu/
Configuration/Communication/SLM configuration/Rear optical SPA-IEC-
DNP port/IEC60870–5–103
Set the same slave number and baud rate as set in the IEC master system for the IED.
Verifying the communication
To verify that the rear communication with the SMS/SCS system is working, there are
some different methods. Choose one of the following.
Verifying SPA communication
Procedure
1.
Use a SPA-emulator and send "RF" to the IED. The answer from the IED should be
the type and version of it, for example, "REL670 2.1...".
2.
Generate one binary event by activating a function, which is configured to an event
block where the used input is set to generate events on SPA. The configuration must
be made with the PCM600 software. Verify that the event is presented in the SMS/
SCS system.
During the following tests of the different functions in the IED, verify that the events and
indications in the SMS/SCS system are as expected.
Verifying IEC communication
To verify that the IEC communication with the IEC master system is working, there are
some different methods. Choose one of the following.
