Trigger Mode setting

By setting the Trigger Mode, you can determine the intervals at which the sensor records the
measurement values.
To set the trigger mode, proceed as follows:
Instruction:
a) In the menu, select the Parametrization | Global Parametrization mode.
b) In the Global Parameters window, proceed to Data Acquisition | Trigger Mode.
c) Set the desired trigger mode.
The following trigger modes are available:
Free Running:
n
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.
Interval:
n
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 meas-
urement cannot start at the set interval. The sensor then waits until the next defined interval
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.
Single Shot:
n
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/OX200.
Encoder:
n
Use the encoder input for synchronisation with an external movement, such as a conveyor
belt.
INFO
For the Single Shot and Encoder modes, the sensor must be connected to an external device.
If an encoder is connected to the sensor, the measurement value recording can be triggered by
the encoder steps (see also

External triggering [} 43]).
