7.5.3.6 Measurement of a web (measurement type 13)
Measuring points for determining the position of a web ($AC_MEAS_TYPE = 13)
A web is measured by approaching the two outside corners or inner edges. The web center
can be set to a setpoint position. The component of the approach direction determines the
web position.

The values of the following variables are evaluated for measurement type 13:
Input variable Meaning
$AC_MEAS_VALID Validity bits for input variables
$AA_MEAS_POINT1[axis] Measuring point 1
$AA_MEAS_POINT2[axis] Measuring point 2
$AA_MEAS_SETPOINT[axis] Setpoint position of web center *
$AC_MEAS_DIR_APPROACH 0: +x, 1: -x, 2: +y, 3: -y, 4: +z, 5: -z
$AC_MEAS_ACT_PLANE Calculated as active plane unless otherwise specified *
$AC_MEAS_FINE_TRANS 0: Coarse offset, 1: Fine offset *
$AC_MEAS_FRAME_SELECT Calculated as additive frame unless otherwise specified *
$AC_MEAS_T_NUMBER Calculated as active T unless otherwise specified (T0) *
$AC_MEAS_D_NUMBER Calculated as active D unless otherwise specified (D0) *
$AC_MEAS_INPUT[0] Approach direction for 2nd measuring point for a recess
measurement. Must have the same coordinate as the
approach direction of the 1st point. *
