D27 – Write to a freely definable table
With the D27 function you write to the table that you previously
opened with D26.
You can write several column names in a D27 block. The column
names must be written between quotation marks and separated
by a comma. You define the values that the TNC is to write to the
respective column with Q parameters.
Note that by default the D27 function writes values
to the currently open table also in the Test run
mode. The
D18 ID992 NR16 function enables you
to query in which operating mode the program
is to be run. If the
D27 function is to be run only
in the Program Run, Single Block and Program
Run, Full Sequence operating modes, you can skip
the respective program section by using a jump
command, page 301.
You can write only to numerical table fields.
If you wish to write to more than one column in a
block, you must save the values under successive Q
parameter numbers.
Example
You wish to write to the columns “Radius,” “Depth” and “D” in
line 5 of the presently opened table. The value to be written in the
table must be saved in the Q parameters Q5, Q6 and Q7.
N53 Q5 = 3.75
N54 Q6 = -5
N55 Q7 = 7.5
N56 D27 P01 5/5/"RADIUS,DEPTH,D" = Q5
