Communication via the rear ports

LON communication
LON communication is normally used in substation 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 28: Example of LON communication structure for a substation
automation system
An optical network can be used within the substation 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.
