15. 1-Wire configuration
LM5 Power (LM5p-DW1) has two 1-wire interfaces built-in. 1-wire is a bus technology which is
built based on client-server topology and allowing to connect up to 100 devices to one
controller. It is either 2-wire or 3-wire bus installation. In case of 2-wire system, a parasitic
powering is used directly from the bus, normally up to 20 devices can work in this way. In case
of bigger amount of 1-wire sensors, you can use LogicMachine 5V DC output to power 1-wire
devices.
Advantages of 1-wire over KNX:
No need in ETS
Very cost-effective
You can use the same wiring as KNX does and connect all standard sensors
Advantages of 1-wire over resistive sensors:
Substantial savings on equipment
Easier connection diagram allows to reduce the complexity of laying wiring
Extension possibility: connection of additional sensors without changing basic wiring
Ability of remote monitoring of sensors (open circuit, short circuit etc.)
No need to take into account the resistance of conductors like in the circuit with
resistive sensors
