2.2.12 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 FCU and X-Feeder
and machines CAN bus controlled the "Feeder Can Bus". The data and power supply from the
FCU to each feeder is contactless.

2.2.12.1 Tape Cutter and Nozzle Changer - Communication
Description of CAN node NC tape cutter module 2
The introduction of the SIPLACE X4I and the further development of the SIPLACE X series also
brings with it the integration of the nozzle changer control and the monitoring sensors into the
machine CAN bus. This new board is named "CAN node NC tape cutter module" [03052927-xx]
and is used in place of the former tape cutter board. This board contains the control system for
the tape cutter unit, NC 1 & 2, nozzle station (blast air valve for C&P20 head) and sensors for the
component/nozzles reject bin. The firmware for the CAN nodes is loaded onto the tape cutter
board with the help of the station software or CACCIA. The "CAN node NC tape cutter" is
backwards compatible with the old tape cutter boards. This assembly can therefore be used in X,
HF and D series machines.

Based on the cables connected and the position of the DIP switch, the CAN processor detects
which functions are to be controlled and at which location each assembly is.
LEDs - meanings
Cable assignment at connector X1
The power connection has 2 pins for selection of the suitable CAN ID. This depends on the
position (location) of the CAN node module in the machine.
NOTE: The old nozzle changer of the C&P20 head can not be used together with the CAN node
NC tape cutter module.
The nozzle changer with new control board can also be used in machines without the CAN nodes.
