3 Functions/function blocks

3.1 L_TpConfigDigInX − Touch probe input configuration

Function

With this function you can configure the signal sensitivity and dead time compensation of the touch

probe inputs from a POU.

· This makes, for instance, length measurements easy.

Declaration

INT L_TpConfigDigInX (byDigInSel, byEdgeDetection, dnTpDelay_p);

Transfer parameters Data type Info/possible settings

byDigInSel Byte Touch probe input 9300 Servo PLC Drive PLC ECSxA

1 DIGIN1 ü − −

2 DIGIN2 ü ü −

3 DIGIN3 ü ü ü

4 DIGIN4 − ü ü

byEdgeDetection Byte Signal sensitivity

0 Rising signal

1 Falling signal

2 Rising & falling signal

3 TP detection off

dnTpDelay_p Double integer Dead time compensation of the touch probe sensor

· Value in [inc] referred to the touch probe source.

· Positive values lead to dead time compensation, negative values to a delay of the touch probe

signal.

Note: dnTpDelay serves to compensate a dead time of the touch probe source used. The indication

in increments required here (normally a date would be indicated) can be calculated by multiplying

the dead time given by the manufacturer of the TP sensor by the current speed. This value (in

increments) must be written cyclically via the L_TPConfigDiginX function. The longer the time

distance between the calls of this function, the higher is the inaccuracy in the TP position detection

since changes in speed between the calls are not considered.

Return value Data type Value/meaning

Double integer Status

0 OK, no error.

−20 The input selected under byDigInSel has not been configured as a touch probe

input in the DDS control configuration.

−30 The input selected under byDigInSel does not support this functionality or

byDigInSel is impermissible, e. g. in case of 0 or 5.6 .

−40 byEdgeDetection is not within the valid range.
