Section 6 Establishing connection and verifying the
SPA/IEC communication
6.1 Entering settings
If the IED is connected to a monitoring or control system via the rear SPA/IEC103 port,
the SPA/IEC103 port has to be set either for SPA or IEC103 use.
6.1.1 Entering SPA settings
The SPA/IEC port is located on the rear side of the IED. Two types of interfaces can be
used:
• plastic fibres with connector type HFBR
• glass fibres with connector type ST
When using the SPA protocol, the rear SPA/IEC port must be set for SPA use.
Procedure:
1. Set the port for SPA 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 a SPA port.
2. Set the SlaveAddress and BaudRate for the rear SPA port on the local HMI under
Main menu/Configuration/Communication/Station communication/SPA/
SPA:1. Use the same settings for these as is set in the SMS system for the IED.
6.1.2 Entering IEC settings
The SPA/IEC port is located on the rear side of the IED. Two types of interfaces can be
used:
• plastic fibres with connector type HFBR
• glass fibres with connector type ST
When using the IEC protocol, the rear SPA/IEC port must be set for IEC use.
