3.3.6 CAN-Bus Concept with One Wire Bus e.g. SiplaceX3
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. 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

3.3.7 CAN Bus Processor Board C&P Head
Can bus processor board TQM 167 LC is mounted on the head board C500. The processor board
is used at different places in the machine.
If the processor board on the head board, the firmware provides at the processor board the control
of the head specific actors and sensors no matter which head type is installed.
3.3.7.1 CAN Bus controlled function on 6/12C&P Head
The following overview shows various head functions, controlled by the CAN system. Thus, the
CAN bus controls the actuators and sensors of the C&P Head.

NOTE:
The status of the 16 Bit PROCESSOR BOARD is indicated on the 7-segment display.
Normal status on the diplay is: Display shows slowly flashed " . "
(Description of the 7-segment display see chapter C&P Head).
