The tools in the False branch are executed if TriggerId is greater than zero.
Device Settings
In the Device Control Drawer
The Device Settings tool dynamically changes some of the settings on the Impact device. Settings made with
this tool are retained in the Impact device until they are changed in the VPM Settings Tab or another Device
Settings tool.
Some settings are dependent on the type of camera being used. See “Camera Setup Tab” on page 2-17 for
more details about these Impact device settings. If a setting does not apply to the camera being used, it is
ignored.
Changing any of these settings while the camera is being triggered and acquiring images can cause the
images to be corrupted. The camera should be offline or triggers should be stopped while these settings are
being changed.
Input Name What it is
Enable Camera
Digital Shift
If True, this tool’s Camera Digital Shift value is sent to the camera when
the tool runs.
Camera Digital Shift Digital shift provides digital gain for the image.
Enable Camera
Gain
If True, this tool’s Camera Gain value is sent to the camera when the tool
runs.
Camera Gain Gain adjusts the actual signal intensity from the camera.
Enable Camera Off-
set
If True, this tool’s Camera Offset value is sent to the camera when the
tool runs.
Camera Offset Offset adjusts the zero grey-level setting for the camera. Adjusting the
offset causes the entire image to brighten or darken. Images become
darker as the offset is increased.
The Branch tool evaluates the
expression:
TriggerID < 0.
If it is True, this is the first image so
the Camera Trigger tool snaps a
second image and assigns it a posi-
tive ID number. The Sample Top
tool then processes the first image.
If the Trigger ID is positive, it
is the second
image from
the Camera Trigger tool so
the image is processed by
the Locate Label tool.
