Smart PLC Unit for multi-scanner applications
The Smart PLC Unit from Micro-Epsilon enables to calculate
the measurement values obtained by up to eight laser
scanners. This is necessary with many applications, e.g. the
contour measurement of large components.
The scanCONTROL Smart PLC Unit is an industrial control
unit for measurement value calculation intended for laser
scanners of the scanCONTROL Smart and gapCONTROL
product classes. The Smart PLC Unit is equipped with
customer-specific application software for the respective
measurement tasks. The determined measurement values
are evaluated, displayed, recorded and transmitted via the
Smart PLC Unit to higher-level control systems using analog
and digital interfaces.
Up to eight laser scanners can be connected to this smart
control unit. Micro-Epsilon laser scanners are among the
highest performing profile sensors in the world with respect
to size, accuracy and measuring rate. Their operating
principle is based on the laser triangulation technique for
two-dimensional profile detection. They detect, measure and
evaluate profiles on different object surfaces. By using
special lenses, a laser beam is enlarged to form a static
laser line instead of a point and is projected onto the target
surface. An optical system projects the diffusely reflected
light of this laser line onto a highly sensitive sensor matrix. In
addition to distance information (z-axis), the controller also
uses this camera image to calculate the position along the

laser line (x-axis). These measured values are then output in
a two-dimensional coordinate system that is fixed with
respect to the sensor. In the case of moving objects or a
traversing sensor, it is therefore possible to obtain 3D
measurement values.
The Micro-Epsilon product range includes laser profile
scanners with either red or blue laser diode. Each one has
its specific advantages. The Blue Laser Technology is
normally applied when the red laser which is used in
common measurement tasks is performing at its limits.
Unlike the red laser, the blue laser light does not penetrate
the measurement object and projects a sharp line.
Therefore, mainly organic objects and semi-transparent
objects can be measured reliably. With red-hot glowing
objects, the blue laser demonstrates its strengths offering a
maximum, spectral distance from the infrared light. The blue
laser is therefore insensitive to red radiation as is the case
with glowing metals. Generally each individual application
needs to be checked in order to determine which laser light
provides the more precise results.
