5 Event timer 0 ... 65535 The event timer sets the time between two
transmissions from the TPDO in [ms]. A value
of 0 deactivates the transmission of the
process data. The smallest logical value rec‐
ommended here is 10 ms.
8.4 General notes on operation
8.4.1 Output of line center points
The OLS10 is capable of detecting up to three line center points (LCPs). The position of
each line center point is output to a resolution of 1 mm. The geometric center of the
sensor’s longitudinal axis is the zero point,
see "optical center", page 12 .
By default, the positive measuring range is towards the cable outlet, and the negative
measuring range is on the opposite side.

If only one line center point is found, this is output as LCP2. If a further line center point
is found, it is output as LCP1 or LCP3, depending on its direction. If three LCPs are
found, then each LCP is output.
If there are multiple tracks in the field of view, the track closest to zero is the main track
(LCP2).
To make it easier for the control system to evaluate this data, the combination of tracks
detected is output in an additional data item #LCP. The LCPs are binary-weighted:

detected
no yes no 2 Only one track detected
yes yes no 3 Single diverter on the minus
side detected (factory set‐
ting)
no yes yes 6 Single diverter on the plus
side detected (factory set‐
ting)
yes yes yes 7 Double diverter detected
The principle of LCP1 < LCP2 < LCP3 always applies to the LCPs.
8.4.2 Inversion of the relative position
This function enables the user to invert the convention that the positive range is at the
cable outlet. This makes it easier to install the sensor when rotated by 180°.
The position can be inverted via CANopen or Ethernet.
