9.2.6 Trigger Mode setting
By setting the Trigger Mode, you can determine the intervals at which the sensor records the
measured values.
To set the trigger mode, proceed as follows:
Instruction:
a) Select mode Parametrization | Global Parametrization in the menu.
b) In the Global Parameters window, proceed to Data Acquisition | Trigger Mode.
c) Set the desired trigger mode.
The following trigger modes are available:
n
Free Running:
The sensor measures constantly at the highest possible frequency (which varies according
to the application).
▪ If the sensor input IN 1 (sync in) is connected, the free-running mode runs when the input
is set to low level.
▪ If the sensor input IN 1 (sync in) is not connected, the free-running mode runs continu-
ously.
n
Interval:
Measuring cycle with a fixed internal interval (µs). Use the Interval mode for measurement
with a precisely defined time interval. The achievable measurement frequencies are theoret-
ically identical to the Free Running trigger mode. The sensor attempts to constantly comply
with the set interval. However, if the sensor is handling an earlier measurement, the mea-
surement cannot start at the set interval. The sensor then waits until the next defined inter-
val point is reached. This means that the measurements are always taken at a multiple of
the set interval.
▪ If the sensor input IN 1 (sync in) is connected, the interval mode runs when the input is set
to low level.
▪ If the sensor input IN 1 (sync in) is not connected, then the interval mode runs continu-
ously.
n
Single Shot:
The sensor records exactly one measured value as soon as it is triggered by an external
pulse. The IN 1 (sync in) input detects only falling edges (transitions from high level to low
level). As soon as the IN 1 (sync in) input is set to high, all output functions are frozen in
their last state until the next measurement. For the specification of input IN 1 (sync in),
please see the data sheet that is available for download at www.baumer.com/OX100.
INFO
Mode Single Shot requires the sensor being connected to an external trigger signal during the
measuring operation.
