10 Operating modes
10.1 Continuous mode
The default mode is the “Continuous mode”.
The sensor continually measures and compares the measured profiles to the activated reference
profile, taking into account the switching threshold.
10.2 Triggered mode
In this mode, the sensor starts the measurement after receiving an external trigger signal.
The sensor compares a single profile to the activated reference profile taking into account the
switching threshold.
The external trigger signal must be provided by the higher-level process control unit (e.g. PLC) and
can be transmitted physically via pin 5 or via IO-Link.
The sensor then signals the successful start and the end of the measurement via the ready signal
(OUT2) or IO-Link. The higher-level control unit has full control of the assessment time.
Use the [Output mode] parameter to set the behaviour of the switching output (OUT1). Submenu
[Configuration] (
[Output mode] = [no delay]: The sensor reacts with a static switching signal at switching output OUT1.
[Output mode] = [On impulse]: The sensor reacts with a pulsed switching signal at switching output
OUT1.
The signal curves and signal values shown here apply to the setting: [Output function] = [high
active] and
[Output logic] = [PNP]. Submenu [Configuration] (
