Interfacing with a Cognex camera

  • Does anyone have experience interfacing directly with a Cognex camera or barcode reader?
    I have an R30iB+ Mate. I am looking into what type of data I may be able to read, store, and send to a PLC.
    Basically I need to read the code, determine the location of the code, calculate an offset to print another code next to the original, and then send the code to a PLC.
    We are replacing an Adept with an LR Mate and the Adept is currently doing all of these operations.

  • I have a few robots with Ethernet/IP connected to Cognex cameras. It has pretty limited capability compared to a serial interface or using Karel. My application is very basic so I'm triggering the camera with EIP and then using the CIO-Micro to read the discrete outputs from the camera. I didn't spend much time getting specific X, Y, Angle data out of the camera. The attachment shows the DIO configuration that matches the EIP config in the Cognex camera and the EIP config in the robot.

  • Hello,
    I've successfully used Cognex 7000 Series camera with profinet molex card (fanuc robot was master). We've used profinet because our whole system in that project was profinet-based. If you install Cognex insight explorer (camera config software downloadable for free online), there is a chapter in help documentation describing camera communication with Fanuc and other robot manufacturers.

    I have used socket messaging, then communicate with the cognex via serial. Then have karel write the offsets to the registers.
