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 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.
