24.2.2.2. Example of building a graph
As an illustration of the process of building a graph for solving a specific problem,
let's find the distance between points 1 and 2 (the wide base of the trapezoid) on the profile
and transfer it to an external controller via the Ethernet/IP protocol.
Source profile. It is necessary to find the
distance between points 1 and 2.
Configure the algorithm for approximating
the profile by segments to obtain a stable
splitting in accordance with the profile
shape. See par.
24.2.1 .
Place two “segment detector” blocks in
the graph building area to select the left
and right segments. Segments are
highlighted by search areas. In the
parameters (see par.
24.1.2 ) for block "0"
select "Mode" > "first", for block "1" -
"Mode" > "last" (the first block works with
the first segment, the second block works
with the last segment).
Place the “seg-seg distance” block in the
graph building area. This block is designed
to calculate the distance between the right
point of the first segment and the left point
of the second segment. In the parameters
(see par.
24.1.2 ) for block “2” select
“Mode”> “end <-> begin”. Connect the
outputs of blocks "0" and "1" with the
inputs of block "2".
