Figure 123: Example of LON communication structure for a station automation
system
An optical network can be used within the station automation system. This enables
communication with the IEDs through the LON bus from the operator's workplace,
from the control center and also from other IEDs via bay-to-bay horizontal
communication. For LON communication an SLM card should be ordered for the
IEDs.
The fibre optic LON bus is implemented using either glass core or plastic core fibre
optic cables.
