A datum table saves positions on the workpiece. To use a datum table, you must activate it. Within an NC program, the datums can be called, e. g. to execute machining processes on several workpieces at the same position. The active row of the preset table serves as the workpiece preset in the NC program.

The names of tables and table columns must start with a letter and must not contain an arithmetic operator (e.g., +). Due to SQL commands, these characters can cause problems when data are input or read.
Editing a datum table
You can edit the active datum table during program run.
