did not specifically define the measured-value
transfer with parameter Q303 when defining the
cycle.
In these cases the TNC outputs an error message, since
the complete handling of REF-referenced datum tables
has changed. You must define a measured-value transfer
yourself with parameter Q303.

preset in the active datum table. The reference system is the
active workpiece coordinate system. The value of parameter
Q305 determines the datum number.

preset in the preset table. The reference system is the machine
coordinate system (REF coordinates). The value of parameter
Q305 determines the preset number.
Cycle 247 in the part program.
Measurement results in Q parameters
The TNC saves the measurement results of the respective touch
probe cycle in the globally effective Q parameters Q150 to Q160.
You can use these parameters in your program. Note the table of
result parameters listed with every cycle description.
