  1. Using Banner Vision Products with OCS Controllers Ken Jannotta Jr. Horner APG August 2007

  2. Design Goals • Use logic and I/O from the OCS to control the vision sampling. • Display the vision samples on the OCS screen. • Save photos of failed parts to the compact flash on the OCS. • Minimize wiring in the system.

  3. Connections Ethernet Switch Ethernet Video out from camera to VIM on OCS

  4. Communications • Programming and monitoring from the PC to the OCS is performed using CsCAN TCP. • Communication from the OCS to the Vision sensor is performed with Modbus TCP. (OCS is the master.) • Communication from the PC to the vision sensor uses a proprietary protocol from Banner.

  5. Communications • Banner Setup

  6. Communications • Banner Setup

  7. Communications • OCS Setup

  9. Video Setup For image format use JPG for smaller file size. File size = 40K Capture time = 5 seconds Use BMP for more captured detail or faster captures File size = 600K Capture time = 2 seconds

  10. Capturing Video • To capture video set the bit setup to capture the desired channel. • Additional logic can be added to record missed captures. The capture bit is reset by the firmware when a capture is complete.

  11. Parameters Available from the Banner Unit • Trigger, teach product change…bits • Some bits have ack • Pass/Fail bits and counts • I/O status, error information • Bar code handling information • Location information

  12. Performance Considerations • Event trigger to capture 2 Scans + < 100mS (Modbus rate) Use input on camera for higher speeds • Video capture performance 1 scan + 1 frame (33ms @ 60 hz)

  13. Graphic Overlays • There is an un-documented featured shown in the OCS demo that allows overlaying bitmaps on video with transparent sections. Special color that is transparent on video Red = 16 Green = 0 Blue = 0 All other colors are opaque
