4.3.4 CAN Bus Processor Board C&P Head
The TQM 167LC CAN bus processor board is connected to the head board. 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 actuators and sensors no matter which head type is
installed.
4.3.4.1 CAN BUS-Controlled Functions on the C&P12 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.

4.3.5 CAN Bus Terminator
The A3 assembly ensures that the CAN bus also functions with undocked CO tables. During undocking,
a CAN terminating resistor is switched, which maintains the CAN bus function and communication.
There is an A3 assembly in each sector.

4.3.6 CAN I/O Module (SLIO) - SIPLACE D4
There are 2 CAN Bus I/O modules in the D4 machine. Both modules are absolutely identical and are
located in sectors 2 and 4.
Functions
Micro controller with integrated CAN controller
Data memory
Program memory (flash)
CAN interface with 9 pin connector and address alignment
16 digital Output 24 V with status LED
24 digital Input 24 V with status LED
Download interface
Power supply 5 V and 24 V
Extension on I/O module for the CAN interface (CO tables)
8 digital inputs can be logically linked with the help of a FPGA (freely programmable gate array). The
FPGA is used for incoming security messages.
