5.8.7 PLC Grabber Features
IPEngine Æ Grabber Æ Channel0 Æ AcquisitionConfiguration
GrbCh0AcqCfgMemoryWaterLevel: the camera has 16MB of memory for frame buffering. Water level setting
specifies how much of that memory to use with the AcquistionMode’s recording features. Once the buffer is full
no more images will be stored. Possible settings are:
−
Level50: 50%
−
Level75: 75%
−
Level87Point5: 87.5%
−
Level100: 100%
GrbCh0AcqCfgInvertPixelData: invert pixel data turning the image into a negative image.
−
True: turn on pixel inversion.
−
False: turn off pixel inversion.
IPEngine Æ Grabber Æ Channel0 Æ TriggerConfiguration
GrbCh0TrigCfgFrameToSkip: set the number of images to discard for every one it keeps from the camera head.
5.8.8 IPEngine Examples:
Example 1: Setting the camera to accept external trigger signal:
1. Set ExposureMode to one of the Asynchronous modes.
2. Setup SignalRoutingBlock
a. Goto IPEngine > ProgrammableLogicController > SignalRoutingBlock
b. Set Trigger Input line by setting PLC_I0 to External_Trigger_In_Pin6
c. Set Camera Strobe Output by setting PLC_I4 to “Internal CAM_STROBE_Out”.
3. Setup the PLC to route the external trigger signal to the camera’s trigger line.
d. Goto IPEngine > ProgrammableLogicController > LookupTable > Q0/Q4/ Q5
i Set PLC_Q0_Variable0 to PLC_I4 (Strobe output)
ii Set PLC_Q4_Variable0 to PLC_I0 (Trigger Line)
iii Set PLC_Q5_Variable0 to One. (Integration signal always on.)
Example 2: Setting the camera to accept internal trigger signal generated via Timer 1:
1. Set ExposureMode to one of Asynchronous modes.
2. Setup the Timer (Pulse Generator)
a. Set TimerSelector to Timer1.
b. Set TimerTriggerSource to Continuous.
c. Set TimerDurationRaw, TimerDelayRaw, TimerGranularityFactor according to values
below.
i These are example values only; other combinations can also be used.
ii TimerFrequency tells you the rate of the trigger, hence frame rate.
<0.5 fps 1 fps 5 fps
TimerDurationRaw 200 200 200
TimerDelayRaw 10000 4550 750
TimerGranularityFactor 7000 7000 7000
3. Setup SignalRoutingBlock
a. Goto IPEngine > ProgrammableLogicController > SignalRoutingBlock
