How the "FG_CAMSTATUS_EXTENDED" variable changes.

    Hi,


    I want to know how the "FG_CAMSTATUS_EXTENDED" variable changes.


    When tested using Basler Camera, the variable is output as 7 after Fg_Init() is executed. However, if you are using a third-party camera, it will output as 1 or 2.


    ** environment of use

    -. Frame Grabber: mE5-VCL

    -. Applet: Acq_SingleFullAreaGray .dll


    Thanks

    Hi IhShin,

    The FG_CAMSTATUS_EXTENDED provides extended infromation on the pixel clock from the camera. The Variable has 8 bit, and each bit provides different information.

    So, 7 would be -> 000 0111 , 2 would be 0000 00010 , and 1 would be 0000 0001 in binary.

    The following link may help to understand what the parameters mean: https://docs.baslerweb.com/fra…tml#FG_CAMSTATUS_EXTENDED


    • 0 = CameraClk, provided by CameraLink interface. Shows if CL PixelClock is available.
    • 1 = CameraLval, provided by CameraLink interface. Shows if CameraLink LVAL is available, representing a line being transferred into frame grabber.
    • 2 = CameraFval, provided by CameraLink interface. Shows if CameraLink FVAL is available, representing frames being transferred into frame grabber. Not relevant for standard line scan applets.
    • 3 = Camera CC1 Signal, NOT provided by this frame grabber.
    • 4 = ExTrg / external trigger, NOT provided by this frame grabber.
    • 5 = BufferOverflow
    • 6 = BufStatus, LSB
    • 7 = BufStatus, MSB

    So for the value 7:

    CL_PixelClock is available, LVAL is available, FVAL is available (First three bits are one) - all others are zero.

    For the value 2 it means that CL_PixelClock is not available, LVAL is available, FVAL is not available.
    For the value 1 it means that CL_PixelCLock is available, LVAL is not available, FVAL is not available.

    Hi Kevin,


    I have one more question.


    If so, is it normal for "7" to be output to the variable after FG_Init() is executed?


    Thanks

    Hi IhShin,

    Sorry for the late reply.


    "Normal" depends on the camera you are using. If the camera provides CL_PixelClock, LVAL and FVAL then a 7 is normal. However, it really depends on the camera that you are using if these are available. If your third party camera does only provide LVAL then the "2" is normal.
