Integration in 1-Wire Network
The 1-Wire Term 1 module is mounted at the end of a 1-Wire network cable.
If the 1-Wire network is star-shaped, i.e. with several 1-Wire cable sections, a 1-Wire Term 1 module should be
connected to each end.
No more than three 1-Wire Term 1 modules should be used in a 1-Wire network.
7.1
Linear Topology
The design corresponds to the linear topology with the difference that the slaves are connected to the main line
via lines with a length of more than 3 m (branch, stub).
7.2
Star or Tree Topology
Here, the network is divided into several large strings at or near the 1-wire bus coupler / 1-wire controller / 1-wire
hub (bus master). Sensors and actuators (e.g. switching modules) are connected at the end or along the
respective string.
