19.5 SPA communication protocol
19.5.1 Application
SPA communication protocol is an alternative to IEC 60870-5-103, and they use the same rear
communication port.
When communicating with a PC connected to the utility substation LAN via WAN and the utility
office LAN (see Figure 113), and when using the rear optical Ethernet port, the only hardware
required for a station monitoring system is:
• Optical fibers from the IED to the utility substation LAN
• PC connected to the utility office LAN

Figure 113: SPA communication structure for a remote monitoring system via a substation
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.

Functionality
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
