can be integrated in one system. Further areas of application are industrial and process automation, supply and disposal,
energy technology, traffic control, etc.

Master versions
LON is a typical multi-master system, in which each device on the bus can have event-controlled transmission. The neuron
controls communication

Topologies
LON is a classic line bus, but it can follow any topology. Since it is possible to choose between star, ring, tree or classic line
structures, this often gives rise in practice to free topologies that are oriented to existing structures in buildings or plants. The
following are used for segmenting such free topologies:
– Repeater | for physical amplification with no processing function
– Router | for the connection of subnetworks
– Bridges | connection of domains
LON devices communicate via different transmission media; as a result, the range of a LON network depends directly on the
transmission medium. If all guidelines are taken into account in the topology structure, a LON network can have a virtually
unlimited size. With the classic TP wiring (twisted pair – two-wires twisted together) the maximum bus length is 1300 m.
