TimerFrequency:
a read-only field that shows the frequency of the pulse in Hz.
TimerGranularityFactor:
a multiplier value used to scale the Delay and the Duration in increments of 30 nsec.
TimerPeriod:
shows the timer’s period in units of nsec.
TimerTriggerActivation:
select the signal state of the TriggerSource to start the Timer.
•
RisingEdge: starts when the trigger signal goes from Low to High
•
LevelHigh: starts when the trigger signal is at the High state.
•
FallingEdge: starts when the trigger signal goes from High to Low.
•
AnyEdge: starts on any Falling or Rising Edge.
•
LevelLow: starts when the trigger signal is at the Low state.
TimerTriggerSource:
select the source of trigger to start the Timer.
•
PLC_Q: the trigger source comes from the PLC Q output. Each Timer has their source from different Q
output port:
• Timer1 trigger comes from PLC_Q9
• Timer1 trigger comes from PLC_Q8
• Timer1 trigger comes from PLC_Q11
• Timer1 trigger comes from PLC_Q10
•
Continuous: the Timer is always running.

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 Examples:
Example 1: Setting the camera to accept external trigger signal:
Set ExposureMode to one of the Asynchronous modes.
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”.
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)
