During the measurement, the workpiece has to be still�
• For static situations, the continuous measurement mode has to be set�
The sensor permanently monitors the workpiece and signals deviations
from the taught reference profile
• For dynamic situations, the triggered measurement mode has to be set�
A higher-level process control unit decides when the detection takes
place and ensures that the workpiece is in the detection zone and that
it does not move

4 Function
The photoelectric sensor detects the height profile of the object in the operating
range, continually or upon triggering, by means of triangulation� Besides, the
photoelectric sensor has an IO-Link interface�
The sensor can be used in three different modes of operation:
• switching mode
• operation with an IO-Link master
• operation with the Vision Assistant via the IO-Link interface
4.1 Operating modes
4.1.1 Switching mode
In switching mode, the sensor is directly connected to the process control unit and
transmits information on good part / bad part via the switching output�
If the set switching threshold is exceeded/not reached, this is signalled by
means of switching signals on switching output 1/2� The switching outputs
act complementary
As an option, the time at which the measurement is taken can be controlled by a
process control unit via the trigger input (pin 5)� The sensor signals the successful
start of the measurement and the availability of switching information via switching
output 2� The higher-level process control unit defines the measurement period�
