for the definition:
Show the soft-key row with special functions
Select the menu for defining various plain-language
functions
Select transformations
Select datum shifting with TRANS DATUM
Select datum shifting with TRANS DATUM TABLE
Enter the line number to be activated by the TNC, and
confirm with the ENT key
If desired, enter the name of the datum table from
which you want to activate the datum number, and

a datum table, confirm with the NO ENT key
Beispiel: NC block
13 TRANS DATUM TABLE TABLINE25
If you have selected a datum table in the TRANS DATUM
TABLE block, then the TNC uses the programmed line
number only until the next call of a datum number
(blockwise effective datum shift).
If you did not define a table in the TRANS DATUM TABLE
block, then the TNC uses the datum table already selected
in the NC program with SEL TABLE or the datum table with
status M selected in one of the Program Run modes.
