The communication speed of the LON bus is set to the default of 1.25 Mbit/s. This can be changed
by LNT.
The LON communication setting parameters are set via the local HMI. Refer to the Technical
manual for more detailed specifications.
If LON communication from the IED stops because of illegal communication parameter settings
(outside the setting range) or due to other kind of disturbance, it is possible to reset the IED's
LON port.
LON communication setting parameters (Table 15) and LON node information parameters (Table
16) can only be set via the LON Network Tool (LNT).
Some of these parameters can be viewed on the local HMI under Main menu/Configuration/
Communication/Station communication/Port configuration/SLM optical LON port/LONGEN:1.
