Description

Sensor Principle / Evaluation Logic
The sensor performs measurement value acquisition as a
continuous signal that is evaluated for switching signal
generation. Evaluation is carried out based on the Transdu-
cer Signal value.
Switching points are defined by means of setpoints that
can be determined using various teach processes. Alterna-
tively, the setpoints can also be set directly via ISDUs, but
under observation of the same requirements and rules as
defined for the teach processes.
SSC Overview – Profile
– Multiple switching channels are possible (up to 2 chan-
nels currently supported).
– Two switching points (setpoints) per switching channel.
– Adjustable hysteresis.
– Several switching modes are possible: Single Point
Mode, Two Point Mode and Window Mode, additio-
nally for SSC1: Single Point Positive Dynamic Mode,
Single Point Negative Dynamic Mode, Single Point
Positive Threshold Tracking Mode and Single Point
Negative Threshold Tracking 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.

Alarm in Single Point Mode
Fig. 8-8: Switching Point Logic Alarm Timing
In Single-Point Mode, an alarm is detected for signals that
only just exceed SP1. This is displayed by a 50ms pulse
on a red LED and can also be output on pin 2.
At the same time, an event warning "Low signal quality
level" is sent.
