Triggering

The measured value output of the combiSENSOR KSB6430 can be started via an external trigger signal or a software command. Only
the digital output is affected.
Triggering takes place via:
- Trigger input (pin 3 and pin 4 on 4-pole power supply connector or
- U , HIGH 2.0 V
≥
IN
- U , LOW ≤ 0.8 V
IN

The trigger type is determined by the parameters of the PROFINET device used.
Level triggering (High level) Continuous measured value output with set data rate
for as long as the selected level is active. After that the controller outputs the last
value. The measured value counter is not incremented any further.

Edge triggering. Starts the measured value output as soon as the selected edge is
present at the trigger input. If the trigger condition is met, the controller outputs the
specified number of measured values. The set data rate must be greater than the
maximum trigger frequency. If triggering is faster than the set data rate, individual
measured values are sent twice because no new measured values are available
internally from the AD converter.
The duration of the pulse must be at least 5 µs.
