2.2.5 CAN Bus Concept SiplaceX2
The placement machine SIPLACE X2 uses a bus system with 1 Mbit/s transmission rate.The
CAN: Bus system begin at the Communication board and is split in 2 path. Every path is termi-
nated by a 120 ohm terminator on the head board at the individual placement head
Fig. 2.2 - 12 CAN Bus overview Siplace X2
Note: When the Twin head is mounted, the switch for the terminator on the head board (C500)
have to be OFF. 2

2.2.6 One Wire Bus
2.2.6.1 Siplace HF/HF3
The placement machine SIPLACE HF/HF3 uses with the Software 505 an additional bus system,
which are integrated into the CAN Bus cable --> One Wire Bus.
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. Independent of the circuit diagram,
on the Main- and Subdistributor are installed the control unit of the one wire system. A kind of
switch are located on the other units which required the one wire system (see figure below). This
switch open and close the communication path.
Controlled components with the ONE Wire Bus:
– Nozzle changer of the C&P heads
– Temperature sensors
– Gantry recognition (CFK02, CFK04, CFK06)
– Option Reject Box

2.2.6.2 Siplace X3 with CAT 5 (e.g. PA 1)
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. On the Main- and Subdistributor are
installed the control unit of the one wire system. A kind of switch are located on the other units
which required the one wire system (see figure below). This switch open and close the communi-
cation path. Controlled components with the ONE Wire Bus:
– Nozzle changer of the C&P heads
– Temperature sensors
– Gantry recognition (CFK02, CFK04, CFK06)
– Option Reject Box
