4.3.6 Communication SIPLACE Vision

Overview SIPLACE Vision

The communication between the computers is via LAN cables. The station computer sends the

commands for image acquisition to the Vision computer and receives the measurement result. The

station computer also sends the illumination values for the respective component shapes. The images

recorded are transferred digitally via the Vision board to the hotlink adapter, using the spread spectrum

and are then sent via the hotlink connection to the Vision computer, for evaluation. The result is sent to

the station computer.

Communication During Image Acquisition

4.3.6.1 Communication During Image Acquisition

The main communication between the Vision system and station computer is the transmission of

illumination values. These values, stored in the CS, 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 trigger. From this

moment on the row of LEDs which provides the different illumination levels shines according to the

illumination value. This illumination value can have 0 = dark up to 255 = bright. All illumination levels start

lighting at the same moment. The value 0-255 determines the length of the illumination time.

The maximum length of illumination is limited to 6 ms.

4.3.7 Communication DP Drives, C&P20A and CPP Head

The TQM module on the head interface C500 communicates via the CAN Bus (1M/Bit/s) with the station

computer.

The communication to the C&P20A or CPP head is via an additional CAN Bus, which sends the data

with 500 KBit/s.

The DP axes are controlled via the DP master (SCS). 4 actions are performed by the machine control at

the same time:

▪ Starts a certain rotary axis after pickup/placement (pickup angle/placement angle)

▪ Starts a certain rotary axis after Vision (correction angle)

▪ Waits for a certain rotary axis before Vision (positioning command not allowed)

▪ Waits for a certain rotary axis before pickup/placement (positioning command not allowed)

4.3.8.1 Communication to the DP Drives

The DP drives are controlled via a common hardware

component, the SCS (Single Core Solution). This

consists of two boards, the power and the control

modules, with a microprocessor for the sequence control.

The control data is sent from the head processor and is

then transmitted via the head CAN bus.

The communication with the light barrier Z down is via a

separate interface, directly to the power module. This is

necessary as a light barrier Z down is integrated into each

segment.
