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
outputs EA2/Do0 to EA2/Do4 every servo board can be checked in the provided
slot.

3.3.10 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.

3.3.11 Communication Siplace Vision
The communication between the computers is carried out via LAN cables. The MC send the com-
mands for the image acquisition to the Visionrechner and receives the result of the measuring.
The MC send the illumination values of the corresponding GF.
The taken pictures are sent digital via the Hot link card to the Visionrechner, these evaluated the
picture.The result is sent to the MC.
