Inputs
If the evaluation case is not permanently active, you can configure an input combina‐
tion that activates the evaluation case.

The initial HIGH state is called “Active HIGH” in SOPAS ET. Accordingly, the initial LOW state is called
“Active LOW”.
NOTE
An input combination can also be defined for several evaluation cases, then e.g. two
evaluation cases become active simultaneously.
Although the LMS5xx Lite has two inputs, only IN1 can be used for field evaluation.
Analysis strategy
In SOPAS ET, you choose from the following possible evaluation strategies:
•
Pixel analysis
: The device evaluates the entire area of the field. Each individual
beam is taken into account in evaluation. If an object enters the field, this result is
forwarded to the corresponding output.
•
Blanking
: The device evaluates the entire area of the field. However, objects that
are smaller than the specified size are ignored. An object is only detected if it is
larger than the configured blanking size. However, this only applies to objects that
are at the maximum distance at which they still meet the criteria for the minimum
object size. At greater distances, the set blanking size can no longer be achieved
by the optical resolution of the device. The device behaves exactly as with pixel
evaluation.
•
Contour
: The device also evaluates the existence of a contour, which has to be
fully situated within the evaluation field at all times. This allows the device to
detect, for example, that a door opens outwards or that the position of the device
has changed. It is also possible to detect someone crawling beneath a vertical
evaluation field or a laser beam deflected in a mirror. Blanking can be used to hide
the missing part of the contour up to a certain size.
