4.3.8.1 Communication to the DP Drives
The DP drives are controlled via a common hardware
component, the SCS (Single Core Solution). This
consists of two boards, the power and the control
modules, with a microprocessor for the sequence control.
The control data is sent from the head processor and is
then transmitted via the head CAN bus.
The communication with the light barrier Z down is via a
separate interface, directly to the power module. This is
necessary as a light barrier Z down is integrated into each
segment.

CAN Bus Communication to the DP Drives
4.3.8.2 CAN Bus Communication to the DP Drives
The data is supplied via the head CAN bus, from the head interface to the intermediate distributor.
The four CAN bus commands are identical to those for the C&P20A head:
Starts a certain rotary axis after pickup/placement.
Starts a certain rotary axis after Vision.
Waits for a certain rotary axis before Vision.
Waits for a certain rotary axis before pickup/placement.
EEPROMs on CPP H ead
4.3.8.3 EEPROMs on CPP Head
EEPROMs are present on all boards (except E/D transformer). Various data are stored there, according
to the individual functions e.g. production date, material number, zero point correction values, offset
values, plus operating and statistical data.

Data Transfe r
4.3.8.4 Data Transfer
The communication with the DP drives (CAN bus) is contactless via a transmitter unit (on the back
cover of the CPP head) and a receiver unit (on the valve terminal).
This communication is via 2 channels, whereby channel 1 is responsible for supplying data to the
DP drives and channel 2 is responsible for communication to the Z down light barrier of the axis card
(HCU).
The head CAN bus is in this case not used as a differential CAN bus with the CAN_L and CAN_H
signals but as a 1 wire CAN on the rotor.
X Feeder - Comm unicatio n
4.3.9 X Feeder - Communication
Communication X feeder
The communication between the Feeder Control Unit (FCU) and each X feeder is carried out via a CAN
bus. This CAN bus is only responsible for the communication between the FCU and the feeders and is
controlled by the machine CAN bus.
The data and power supply from the FCU to each feeder is contactless.
