Each servo card get a number (0-16) for the Identification. This number can be
reconstructed from all 4 servo address bus messages. In the interaction with the

3.3.11 CAN: Bus Communication with Axis Controller
In previous Siplace placement machines, the communication and data flow between axis control-
ler and machine controller was achieved using the SMP bus. From the HF machine generation
on, the SMP bus is no longer used with the axis system.
The communication between the axis controller modules is now achieved using the CAN Bus. All
information, which has to be transfered between these modules, is now on the CAN bus (e.g axis
parameter, target position, end signal, ...) This of course means that the number of single tele-
grams increases significantly compared with the amount of data exchange which has occurred
previously.
3.3.12 CAN Bus Communication with Vision system
The main communication between the vision system and CAN bus is the transmission of illumina-
tion values. These values, stored in the GF, are sent via CAN bus to the camera in question. As
soon as the camera should take the picture, the camera illumination is activated by a flash signal,
which travels in a single cable (flash line) to the camera. From this moment on the row of LEDs
which provide the different illumination levels light dependant on the illumination value 0-255. All
illumination levels start lighting at the same moment, triggered by the flash signal.
The value 0-255 determines the length of the illumination time.
The maximum length of illumination is limited to 6 ms.

3.3.12.1 Visionsystem: Flash-Signal
The overview below shows the flash signals, triggered by the ICOS.
The flash signal for the stationary cameras, went via the vision control board (section 4, main dis-
tributor) to the camera in question and triggers the illumination.
The flash signal for the component camera revolving head uses the trailing cable to the vision
board on the head interface.
