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 taught 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 of the measurement, and, a little later,
the availability of the switching information via switching output 2 (ready signal) or
IO-Link� The higher-level control unit has full control of the assessment time
