4.3 Switching Profiles
4.3.1 Description
Sensor principle / evaluation logic
The sensor performs measurement value acquisition as a
continuous signal that is evaluated for switching signal
generation. The measurement value is only evaluated if it is
within this valid measurement range. If the measurement
value is outside of this range, the output switches to
always active. For switching sensors, this value is
permanently defined according to the product.
Switching points are defined by means of setpoints that
can be determined using various teach processes.
Alternatively, the setpoints can also be set directly via
ISDUs, but under observation of the same requirements
and rules as define for the teach processes.
The setpoint setting can also be used to deactivate the
switching point evaluation. This is performed with the No
Measurement Data setting:
Status Value
No Measurement
Data (16 bit)
32,768 (0x7FFC)
No Measurement
Data (32 bit)
2,147,483,644 (0x7FFFFFFC)
Tab. 4-4: Switching Profiles – Deactivate switching point evaluation
Overview AdSS – Profile
– Only one switching channel (Switching Signal Channel
(SSC)) available.
– Only one switching point (setpoint) per switching
channel.
– Permanently defined hysteresis according to the
product.
– As switching mode, only the Single Point Mode is
available.
– The following teach commands are available: Single
Teach , Two Value Teach and Dynamic Teach (profile
spec.).

Primary Device Functions (continued)
Overview of LSSC – Profile
– Multiple switching channels are possible (up to 4
channels currently supported)
– Two switching points (setpoints) per switching channel.
– Adjustable hysteresis.
– Multiple switching modes are possible: Single-Point
Mode , Two-Point Mode and Window Mode .
– The following teach commands are available for both
setpoint 1 and setpoint 2: Single Teach , Two Value
Teach and Dynamic Teach (profile spec. and Balluff
spec.).
Switchpoint Logic
With switching logic High active , the switching output
switches to high if the current value is greater than the set
(taught) setpoint. With Low active this logic is inverted.
