Establishing connection and
verifying the LON communication
Figure 24:
Example of LON communication structure for a substation automation system.
An optical network can be used within the Substation Automation system. This enables commu-
nication with the 670IEDs through the LON bus from the operator’s workplace, from the control
center and also from other IEDs via bay-to-bay horizontal communication.
The fiber optic LON bus is implemented using either glass core or plastic core fiber optic cables.
