Type 4 process data
Type 4 process data outputs the positions of up to six detected traces.
If the sensor finds one trace, the left and the right edge of this trace is output. If the sensors
finds two or more traces, the left and right edges of all valid traces are output. The traces in
the process data are arranged in ascending order according to the position at which they
were found. The trace with the smallest position is always output first and is therefore always
trace no. 1. All subsequent traces are arranged in ascending order according to their posi-
tion and the trace number is incremented.
If filters such as trace width, minimum contrast or trace amplitude are active, they are effec-
tive for PD type 4.
Figure 8.2:
Output of the left edge and right edge with PD type 1.
The "Trace width" filter is OFF in Figure 8.2, recognizable by the fact that the wide trace is
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.
