MC_TouchProbe
Short Description
The touch probe function block is used to record an axis position, master
position or probe time at a trigger event using the drive probe feature.
Note:
Probing cycle procedure command (S-0-0170) must be
activated before execution of MC_TouchProbe. Consequently,
the write request S-0-0170=3 is necessary before
MC_TouchProbe execution.

Name Type Comment
VAR_IN_OUT Axis AXIS_REF Reference to the axis
VAR_INPUT Execute BOOL Positive edge starts the probe function
ProbeType PROBE_DATA_FORMAT Specify the data format of the measured probe signal.
AXIS_POS = 0: Position of the axis (e.g. S-0-0051)
PROBE_TIME = 1: Probe time in us;
MASTER_POS = 2: Master position (e.g. P-0-0053)
ProbeSelect PROBE_NUMBER Specify the selected probe. PROBE1 = 1: Probe 1 is
selected; PROBE2 = 2: Probe 2 is selected
PosEdge BOOL Positive edge of the selected probe will be evaluated
NegEdge BOOL Negative edge of the selected probe will be evaluated
VAR_OUTPUT Done BOOL Selected probe events are recorded
Active BOOL FB is active
PosEdgeDetected BOOL Positive edge of the selected probe was detected
NegEdgeDetected BOOL Negative edge of the selected probe was detected
RecordedPosition REAL Axis position where positive edge occurred (in
technical units according drive scaling). This output is
used in case ProbeType = AXIS_POS
RecordedPositionNe
g
REAL
Axis position where negative edge occurred (in
technical units according drive scaling). This output is
used in case ProbeType = AXIS_POS
RecordedValue DINT Master position (in Increments) or probe time (in us)
where positive edge occurred. This output is used in
case ProbeType = PROBE_TIME or ProbeType =
MASTER_POS
RecordedValueNeg DINT Master position (in Increments) or probe time (in us)
where neagtive edge occurred. This output is used in
case ProbeType = PROBE_TIME or ProbeType =
MASTER_POS
