Establishing connection and verifying the LON communication
• The node addresses of the other connected IEDs.
• The network variable selectors to be used.
This is organized by LNT.
The node address is transferred to LNT via the local HMI by setting the parameter
ServicePinMsg = Yes. The node address is sent to LNT via the LON bus, or LNT can
scan the network for new nodes.
The communication speed of the LON bus is set to the default of 1.25 Mbit/s. This can
be changed by LNT.
The setting parameters for the LON communication are set via the local HMI. Refer
to the technical manual for setting parameters specifications.
The path to LON settings in the local HMI is Main menu/Configuration/
Communication/SLM configuration/Rear optical LON port
If the LON communication from the IED stops, caused by setting of illegal
communication parameters (outside the setting range) or by another disturbance, it is
possible to reset the LON port of the IED.
Path in the local HMI under Main menu/Configuration/Communication/SLM
configuration/Rear optical LON port
These parameters can only be set with the LON Network Tool (LNT).
