Name	Type	Description
Signal	BOOL	Current state of the digital input signal. The current state must be supplied here.
TimestampRisingEdge	T_DCTIME32	Time stamp of the last rising edge of the digital input signal. Only the time stamp of the edge defined via Edge has to be supplied. If the input signal supplies a 64-bit time stamp T_DCTIME, only the lower 32 bits are supplied. It is therefore important to ensure that the value at the time of the evaluation is not older than 2 seconds.
TimestampFallingEdge	T_DCTIME32	Time stamp of the last falling edge of the digital input signal. Only the time stamp of the edge defined via Edge has to be supplied. If the input signal supplies a 64-bit time stamp T_DCTIME, only the lower 32 bits are supplied. It is therefore important to ensure that the value at the time of the evaluation is not older than 2 seconds.
Edge	E_SignalEdge	Edge defines the signal edge to be used for the evaluation of the axis position. TYPE E_SignalEdge : ( RisingEdge, FallingEdge ); END_TYPE
FreeRun	BOOL	If FreeRun is TRUE, the input is latched continuously. In this case the input Execute must remain TRUE in function block XFC_TouchProbe. No edge at Execute is required in order to record the next new position value.
EncoderIndex	UINT	If more than one encoder is connected to the axis, the encoder index [0 – 9] can be defined here. The first encoder has the index 0.
ModuloPositions	BOOL	If ModuloPositions is TRUE, all positions are interpreted as modulo. The parameter ModuloFactor is used for calculating the modulo cycle.
ModuloFactor	LREAL	ModuloFactor indicates the length of a modulo cycle in the positioning unit of the axis and is only used if ModuloPositions is TRUE.
