8.10Touchprobe
Using the touch probe inputs, touch probe functions can be performed. To do this,
P106[0] - MPRO_INPUT_FS_ISD05 and P107[0] - MPRO_INPUT_FS_ISD06
must be used to set digital inputs ISD05 and ISD06 to "PROBE(15) = Touch probe
(only ISD05/06)" (see Section "Digital Inputs" on page 232). HTL encoders can be
evaluated or pulse counters implemented using the MSD PLC.
The touch probe can be triggered with P240 - MPRO_TP_Ctrl. This enables
triggering on a positive or negative edge, or on both edges, of the signal detected on
the touch probe inputs. After the measurement, the parameter jumps back to the
value "NONE (0)" and the latch position is mapped in the corresponding subindex of
parameter P 241 - MPRO_TP_Position. A continuous touch probe mode is not
possible at present, so the touch probe has to be reactivated after the measurement.
P1402 - MPRO_TP_Channel can be used to select various positions as actual
value sources for the latch position for the touch probe functionality.
The following table provides an overview of the available settings. The counters are
accessed via the MSD PLC or a bus system.
