4.3.3 CAN Bus Structure SIPLACE D4
The SIPLACE D4 placement machine uses a bus system with a data transmission rate of 1 MBit/s. The
bus system begins at the communication board and is split in 2 paths. Each path ends with a120 Ohm
terminating resistor at the head board of the respective placement head.
The cutter and the CO table operate with 500 KBit/s , as does the HS60.

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.
