MLG-2 WebChecker - Search Fields

Here, I want to show some information about the use of Search Fields for our MLG-2 WebChecker.

Why do we need search fields?

How does the edge numbering work?

What happens when one object is missing?

To solve the numbering problem, we can use the search fields:

What happens, when we remove one object now?

Cases of use:

Why do we need search fields for MLG-2 WebChecker and how are the edges numbered?
The Search Fields can be useful for applications with changing numbers of multiple edges, so that each detected edge can be clearly allocated to a certain edge number. 

First, we must know how the WebChecker is counting the detected edges:
all detected edges are counted from outward to inward. 
one example with 3 objects = 6 edges and another SOPAS screenshot with 4 edges. 

What happens when one object is missing?
Now we start without using the Search Fields and see which of the following will happen: 

1. The yellow LED starts blinking, related to the material teach-in, which was done before: edge is missing.
2. The edge numbering shows another result = one edge has changed the number.

To solve the numbering problem, we can use the search fields:
Again, we start with 3 objects, but now we choose "with Search Fields" before we perform the material teach-in.
Furthermore we can set the width of search field, for instance +/- 20mm.
If needed, the search fields can also be configured with individual values.



As you see here, the numbering of the search fields is equal to before - according to the material teach, we did before: 


What happens, when we remove one object now?
As you can see, the edge numbering doesn't change anymore!
All assignment of the edge numbers is referring to the search field numbers.
For instance: when any edge is located in the search field 8, it always gets assigned No 8 - it doesn't matter how many other edges are detected!


Cases of use: 
In the rubber industry: for the production of tires, the number of rubber stripes can change according to the production process. 
Please be aware that the maximum number of stripes for one WebChecker is 5 (= 10 edges). For applications with > 5 stripes, we can take 2 WebCheckers side by side.
