Outputs (Variable type: VAR_OUTPUT)
Name Data type Value/Meaning
dnTPDistanceCalculated DINT Touch-probe-sensor position calculated. A modulo arithmetic operation is used to
adjust this value by multiples of the cutting length so that a virtual touch-probe-
sensor position can be calculated as close as possible to the knife. The value is
scaled in 0.0001[m_units].
dnDistanceToXMax DINT Distance calculated from the 6 o'clock position of the knife to the x max. value of the
profile. The value is scaled in 0.0001[m_units].
dnMultipleTPDistance DINT Calculated value indicating the touch-probe-sensor distance in integer multiples of
the cutting length. The value is scaled in 0.0001[m_units].
Status signal indicating whether the touch-probe-sensor position measured plus the
6 o'clock position of the knife calculated in relation to the x max. value of the profile
(dnDistanceToXMax) permits touch-probe correction with or without touch-probe
register control.
TRUE The touch-probe-sensor distance measured plus
dnDistanceToXMax is greater than the cutting length.
Touch-probe correction with a touch-probe register is
required.
bUseShiftedTP BOOL
FALSE The touch-probe-sensor distance measured plus
dnDistanceToXMax is less than the cutting length. Touch-
probe correction without a touch-probe register is required.
nNumberOfKnives INT Number of knives on the cross-cutter drum
