The following terms are used in connection with VSC:
Term Explanation
Reference image A reference image shows a situation in
the working space that you regard as
safe. Therefore only create reference
images showing safe, non-hazardous
situations.
Mid-value image The control creates a mid-value image
taking into account all reference images.
The control compares new images with
the mid-value image as part of evalua-
tion.
Error If you generate an image showing a poor
situation (such as an incorrectly clamped
workpiece), you can generate an "image
of error"
It is not advisable to highlight an error
image as a reference image.
Monitoring area Denotes an area that you highlight
with the mouse. When evaluating
new images, the control only refers to
this area. Parts of images outside the
monitoring area have no effect on the
results of the monitoring process. Sever-
al monitoring areas can be defined.
Monitoring areas are not linked to
images.
Error Area on an image containing a deviation
from the desired position. Errors always
refer to the image for which they were
saved (image of error) or to the image
most recently evaluated.
Monitoring phase No further reference images are
produced in the monitoring phase. You
can use the cycle for automatic monitor-
ing of your working space. In this phase,
the control only issues a warning if
it finds a deviation when comparing
images.
