About this chapter
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.
By setting the parameter LONDefault=YES, the LON communication is reset in the terminal,
and the addressing procedure can start from the beginning again.
There are a number of session timers which can be set via the local HMI. These settings are only
for advanced use and should only be changed after recommendation from ABB.

These parameters can only be set with the LNT, LON Network Tool. They can be viewed in the
local HMI.
