4.5 SPA communication protocol
4.5.1 Application
SPA communication protocol as an alternative to IEC 60870-5-103. The same
communication port as for IEC 60870-5-103 is used.
SPA communication is applied using the front communication port. For this purpose,
no serial communication module is required in the IED. Only PCM600 software in the
PC and a crossed-over Ethernet cable for front connection is required.
When communicating with a PC (as shown in figure
324), using the rear SPA port on
the serial communication module (SLM), the only hardware required for a local
monitoring system is:
• Optical fibres for the SPA bus loop
• Optical/electrical converter for the PC
• PC
A remote monitoring system for communication over the public telephone network
also requires telephone modems and a remote PC.
The software required for a local monitoring system is PCM600, and for a remote
monitoring system it is PCM600 in the remote PC only.
