Type 1 process data
Type 1 process data outputs the position of a left and a right edge.
If the sensor finds one trace, the left and the right edge of this trace is output. If the sensor
finds two traces, then the outermost left edge and the outermost right edge of the detected
traces are output.
If filters such as trace width, minimum contrast or trace amplitude are active, they are effec-
tive for PD type 1.
Figure 8.1:
Output of the left edge and right edge with PD type 1.
The "Trace width" filter is OFF in Figure 8.1 because the wide trace would otherwise not be
detected at the midpoint of the switch.
With active "Trace width" filter, the "Switch" function can be used as an alternative (see
chapter 7.4 "Switch"). In this case, additional information is sent in byte 2 (data) when the
process data is requested.
