3.4.14 POS−TP (Touch−probe saving of the actual position value)
3−92
l
EDSVS9332P−EXT DE 2.0
Procedure:
1. A LOW−HIGH edge at POS−ENABLE−TPx
– switches POS−TPx−RECOGN = LOW.
– switches POS−TPx−ENABLED = HIGH.
2. A signal edge at TP input terminal X5/Ex
– switches POS−TPx−RECOGN = HIGH,
– switches POS−TPx−ENABLED = LOW.
3. The actual position at POS−ACTPOS valid at this time is saved in VTPOS at the corresponding
table position.
4. Another LOW−HIGH edge at POS−ENABLE−TPx
– switches POS−TPx−RECOGN = LOW.
– switches POS−TPx−ENABLED = HIGH.
Tip!
The function block POS−TP is part of POS. Therefore it is not necessary to explicitly transfer it to the
processing.
TP positioning has priority over the POS−TP function. When the same TP input is used
simultaneously, TP positioning takes precedence with regard to the TP enable (also see
chapter 3.4.13.4).
