2.8.1.2 Touch probe (TP)
Process: The current angle value (digital frequency input value) is stored by a quick interrupt in the
operating system when a signal change occurs at the TP activating input (e.g. X5/E5).

Functional sequence
1. The TP is signal-controlled via the digital input X5/E5 or a zero pulse (only when the encoder is
connected).
2. If a TP has occurred,
DFIN_bTPReceived_b is set = TRUE.
3. After the start of the task,
DFIN_dnIncLastScan_p indicates the number of increments [inc]
counted since the TP.
4. Following,
DFIN_bTPReceived_b = FALSE is set.
Note!
• It is necessary that all three outputs ( DFIN_nIn_v , DFIN_bTPReceived_b and
DFIN_dnIncLastScan_p ) are processed in the task even if only one signal is required.
• The polarity of the digital input E5 configured under C0114/5 does not influence the signal
evaluation.
