8.7 Touch probe detection

A "Touch probe" is an event which can for instance be actuated in an edge-controlled manner via a

digital input to detect an actual value (that changes quickly) at the time of activation and to process

it further within the program afterwards.

Overview of the touch probe channels

For the touch probe detection 12 touch probe channels are provided, which can be configured

independently of each other:

• Each touch probe channel is assigned to a system block which provides the application with a

scaled time stamp.

• The time stamp refers to the sampling time of the encoder signals and outputs the difference

with regard to the touch probe event.

Further processing of the touch probe

For further processing of the touch probe event the time stamp is to be transmitted to an instance

of the L_SdTouchProbe FB:

[8-2] Transfer of the time stamp to the L_SdTouchProbe FB

•TheL_SdTouchProbe FB takes over the interpolation of the input signal on the basis of the time

stamp and outputs the interpolated value and the difference to the last input signal.
