ABB RELION RET670, Commissioning Manual, Page: 68 / 328

Procedure:
1. Set the port for IEC use on the local HMI under Main menu /Configuration /
Communication /Station communication/Port configuration/SLM optical
serial port/PROTOCOL:1
. When the communication protocol is selected, the IED
is automatically restarted, and the port then operates as an IEC port.
2. Set the SlaveAddress and BaudRate for the rear IEC port on the local HMI under
Main menu/Configuration/Communication/Station communication/
IEC60870-5-103/OPTICAL103:1
. Use the same settings for these as is set in the
SMS system for the IED.
6.2 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.
6.2.1 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.
6.2.2 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.
