Parameter
_RF
_KNUM
_TNUM
_TNAME
_DLNUM
_TENV
The following additional parameters are also valid:
_VMS, _CORA, _TZL, _TMV, _TUL, _TLL, _TDIF, _TSA, _FA, _PRNUM,
_EVNUM, _NMSP and _K.
_CORA only relevant for monodirectional probe.
The other parameters must also be assigned if _KNUM=0 because they refer to the
workpiece.
The diameter or width difference is monitored here with _TSA.
