7.1.1 LON communication
M12196-4 v5
LON communication is normally used in station automation systems. Optical fiber
is used within the substation as the physical communication link.
The test can only be carried out when the whole communication system is installed.
Thus, the test is a system test and is not dealt with here.

Figure 8: 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.
