RuntimeAcquire Property 
 
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.RuntimeAcquirevar 
VSet  Sequence.Object.RuntimeAcquirevalue 
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
