1.11.1.1 Basic Structure
The one wire bus system consists in principle of a master with EEPROM (control unit), which con-
trols the various submodules such as A/D converters, EEPROM, temperature and I/O modules.
Each communication branch is equipped with an upstream coupler, which opens the branch for
data transfer.

1.11.1.2 One Wire Bus in the HF Machines
The one wire bus in integrated into the machine CAN bus cable and therefore divided into place-
ment areas 1 and 2. The structure or arrangement of the CAN stations is identical with that of the
machine CAN bus. Pin 1 (wire 1) of the machine CAN bus is used for the one wire system.

Depending on the machine configuration (1 or 2 gantries) the one wire bus structure in PA2 is iden-
tical with that in PA1.
1.11.1.3 One Wire Bus in the Siplace X
With the Siplace X-machine the One Wire Bus is integreted in a separate CAT5 cabel, which start
from the Main- and Subdistributor up to the trailling interface. From the trailing interface up to the
head interface the one wire bus goes through the trailling cable. So that the cable structur are dif-
ferent but not the function of the one wire bus. 1
