12.1.2 Entering IEC settings
When using the IEC protocol, the rear SPA/IEC port must be set for IEC use.
Two types of interfaces can be used:
• 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/Settings/General settings/Communication/SLM
configuration/Rear optical SPA-IEC-DNP port/Protocol selection
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/Settings/General settings/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.
12.2 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.
12.2.1 Verifying SPA communication
Procedure
1. Use a SPA-emulator and send “RF” to the IED. The answer from the IED
should be “”.
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.
