2.2.7 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.
2.2.7.1 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 " . "

2.2.7.3 CAN Bus controlled function on the Twin Head
The CAN-Bus Processor-board is no longer on each Twin segment installed. Now, the Twin seg-
ment got a new board and the processor board (TQM) is installed on the head board C500. The
reason is, that we have a defined interface for head modularity.
