Description

Description
The sensor is a two-dimensional color sensor, suitable for detection and inspec-
tion tasks based on colors.
It can be used in two operating modes:
• Color mark analysis (matching) inspects multicolor surfaces for color com-
ponents and their distribution. The sampling window is determined and
evaluated in accordance with its overall color properties. The color compo-
sition of the current image is compared here with the previously taught
samples. The background must not change between inspection runs.
• For color characteristic recognition, the sensor searches for a specific color
and its frequency of occurrence throughout the complete image window.
The frequency of occurrence in the current image is compared here with
the frequency of the color in the previously taught sample. Only the chang-
es in this specific color are recognized and evaluated. This means that the
background or other color characteristics of the test object can differ be-
tween inspection runs because they are not taken into account during the
inspection.
The SIMATIC MV220 compares the results with the taught "Model" and pro-
vides the information as to whether the inspection run was successful or not.
Due to the variable image window, the SIMATIC MV220 can be adapted to the
application and object with regard to resolution and object size.
It is possible to save color samples for up to 16 different objects as models in
the sensor.
Interfacing to a higher-level (automation) system is possible through standard-
ized digital inputs and outputs (X1 plug/X2 socket).
