Figure 124: SPA communication structure for a remote monitoring system via a
substation LAN, WAN and utility LAN
SPA communication is mainly used for the Station Monitoring System. It can
include different IEDs with remote communication possibilities. Connection to a
PC can be made directly (if the PC is located in the substation), via a telephone
modem through a telephone network with ITU (former CCITT) characteristics or
via a LAN/WAN connection.

The SPA protocol V2.5 is an ASCII-based protocol for serial communication. The
communication is based on a master-slave principle, where the IED is a slave and
the PC is the master. Only one master can be applied on each fibre optic loop. A
program is required in the master computer for interpretation of the SPA-bus codes
and for translation of the data that should be sent to the IED.
For the specification of the SPA protocol V2.5, refer to SPA-bus Communication
Protocol V2.5.
13.5.2 Setting guidelines
M11876-3 v6
SPA, IEC 60870-5-103 and DNP3 use the same rear communication port. This port
can be set 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.
The SPA communication setting parameters are set on the local HMI under Main
menu/Configuration/Communication/Station communication/SPA/SPA:1.
