RuntimeAcquire Property
Applies To
Vision Sequence
Description
The RuntimeAcquire property tells the vision sequence which method to use to acquire an image for use
with that sequence.
Usage
VGet Sequence.Object.RuntimeAcquire, var
VSet Sequence.Object.RuntimeAcquire, value
Sequence Name of a sequence or string variable containing a sequence name.
Object Name of an object or string variable containing an object name. The object must exist in the
specified sequence.
var Integer variable that will contain the value of the property.
value Integer expression for the new value of the property.
Values
0 - None This tells the vision system not to acquire an image. Simply use the image which is already
in the frame buffer. This is useful when a series of Vision sequences are to work from the
same image. For example, you could acquire an image in sequence #1. During this sequence
you could also execute some vision objects. Next assume that you want to use another vision
sequence on the same image. Simply set the RuntimeAcquire property to None for the 2nd
vision sequence and the same image will be used for both sequences.
1 - Stationary The camera is stationary (not moving). A new image is acquired at the start of the vision
sequence. This is the normal method for running a vision sequence. Each time a new vision
sequence is executed, a new image is acquired at the start of the sequence. The
ExposureTime property affects how stationary images are acquired. See ExposureTime for
details.
2 - Strobed The image acquisition starts by the trigger input. Also the strobe output is output. This is
the mechanism for setting up strobed lighting for capturing moving images within the frame
buffer. See the remarks section below for more details.
Default: 1 - Stationary
