4.2 LON setting

Remote communication
Use the LNT, LON Network Tool to set the LON communication. This is
a software tool that is applied as one node on the LON bus. In order to
communicate via LON, the terminals need to know which node addresses
the other connected terminals have, and which network variable selectors
should be used. This is organised by the LNT.
The node address is transferred to the LNT via the built-in MMI at:
Configuration
LONComm
ServicePinMsg
By setting YES, the node address is sent to the LNT via the LON bus. Or,
the LNT can scan the network for new nodes.
The speed of the LON bus is set to the default of 1,25 MHz. This can be
changed by the LNT.
If the LON communication from the terminal 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 terminal.
This is performed at the built-in MMI at:
Configuration
LONComm
LONDefault
By setting YES, the LON communication is reset in the terminal, and the
addressing procedure can start from the beginning again.
