5.4 Switching Profiles
5.4.1 Description
Sensor principle / evaluation logic
The sensor performs measurement value acquisition as a
continuous signal that is evaluated for switching signal
generation. The measured value is only evaluated if it is
within the valid measuring 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. The evaluation is based
on the Transducer Signal value (PDObjectId 0x0026 (38)).
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 in compliance with the same prerequisites and
rules that apply to the Teach procedures.
The setpoint setting can also be used to deactivate the
switching point evaluation. This is performed with the No
Measurement Data setting:

Primary Device Functions (continued)
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
Value Teach , Two Value Teach and Dynamic Teach
(profile spec.).
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 Value 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 measurement value is
greater than the set (taught) setpoint. With Low Active this
logic is inverted.
