The JUMO mTRON automation system incorporates the fieldbus network
concept called LON (
A screened twisted pair is used as a transmission line. The connection can be
made as line, ring, star or mixed structure (free topology).
The physical ends are provided at both ends with a termination resistance of
100Ω, which is activated by a switch on the module.
v Section 4.6 "LON termination resistance"
In this wiring arrangement, the network remains functional even when there is
a break. The termination resistance of any one module in the ring must be set
to 50 Ω.
